     BACKGROUND 
     A human hand has numerous bones, including phalanges and metacarpals. Each finger has three phalanges: a proximal phalange, an intermediate phalange, and a distal phalange. A thumb has two phalanges. Phalanges are hinged together with interphalangeal joints. For example, a finger’s proximal phalange and intermediate phalange are joined by a proximal interphalangeal (PIP) joint, while a finger’s intermediate phalange and distal phalange are joined by a distal interphalangeal (DIP) joint. A finger’s proximal phalange is joined to a metacarpal with a metacarpophalangeal (MCP) joint. 
     Unfortunately, accidents or other medical conditions can impact the flexion and/or extension of a finger’s interphalangeal joints. For example, when a tendon used to extend a finger becomes torn while another tendon used to pull the finger toward the palm of the hand remains intact, the finger can become contracted against the palm. Treatment of such an injured finger can involve bracing the finger into a desired position while the finger heals. Some devices have been developed that use screws to move parts into place to brace an injured finger. However, conventional devices fail to achieve sufficed magnitude of force or rigidity on the finger.

     DETAILED DESCRIPTION 
     This disclosure includes systems and implementations for providing an adjustable finger splint usable to treat various finger related injuries. For example, age, injury, or damage to one or more of the figures may cause the fingers to stiffen or lock in a bent or flexed position. For instance, damage or injury to the extensor tendons or ligaments in the finger often cause the finger to lock in a bent or flexed position due to force exerted by the flexor tendons on the finger. In this instance, if the injury remains untreated the finger may remain permanently in a flexed position. However, conventional treatments including casting the finger locks the finger in an extended position for long periods of time. Therefore, the adjustable finger splint discussed herein provides for a splint that allows the user to remove the finger from the splint when the user’s pain threshold is elapsed as well as for the user to self-adjust the amount of pressure applied by the splint at any time during use, thereby, allowing the injury to be treated without the need for continuous casting or long recovery times due to surgery. 
     In some cases, the adjustable finger splint may include a self-contained unit or may be formed as an assembly of two or more separate components. The adjustable finger splint may include a main body that may be permanently or releasably coupled to a slide. The main body may have a front end positioned away from the user during use and a rear end, opposite the front end, or positioned proximate to the user during use. The main body may also include an opening or cavity configured to receive a finger of the user and to hold the finger in place during treatment or use. When the finger is secured within the opening, the user’s finger may be positioned such that the end of the user’s finger is proximate the front end and the palm of the user is proximate the rear end. 
     A slide may be movable, adjustable, or slidable relative to the main body of the finger splint, and, thus movable, adjustable, or slidable relative to the injured finger held immobile by the main body. In these cases, the slide may be used to increase or decrease the pressure applied to the end of the finger by adjusting the position of the slide relative to the main body. In some implementations, the slide may have a wedge that is configured to apply increasing pressure on the end of the finger held within the main body as the slide is pushed or pulled outwards towards the front end of the main body. In this manner, as the slide is moved away from the body of the user, a curvature of the wedge forces the finger further and further toward a fully extended position. Thus, in some examples, the user may gradually reduce the angle of the injured finger relative to the hand (e.g., further straighten the finger) over a period of treatment (e.g., days, weeks, or months depending on the severity of the injury). 
     In some implementations, the slide may be releasably coupled to the main body, such that the slide may be removed or separated from the main body when not in use and, thus, allow for the adjustable finger splint to be more easily stored or carried. In alternative implementations, the finger splint may be configured to prevent loss of the independent components of the splint and, thus while the palm side may be movable or adjustable with respect to the main body, the slide may be affixed, such as via a track, to the main body. In these alternative implementations, the slide and the main body may be inseparable. In some cases, the slide and/or the main body may be formed form a substantially rigid material, such as various plastics, polymers, metals, alloys, polyurethanes, gases, fluids, gels, foams, fibers, or combinations thereof. 
     As discussed above, the adjustable finger splint may include two or more substantially rigid components that apply pressure to an injured finger in a manner to hold the finger in a straighten or extended position. However, in some situations, direct contact between the substantially rigid material of the main body and slide of the splint may result in pain levels that exceeds the tolerance thresholds of the individual being treated, even for a short duration. Thus, the adjustable finger splint may also include a dorsal pad and a palmar pad to increase comfort and reduce pain caused by the finger splint to the user when in use. In some cases, the palmar pad may be secured to the slide below the hand of the user and the dorsal pad may be secured along a bottom of a top surface of the opening within the main body of the adjustable finger splint in a position above the finger. In some cases, either or both of the dorsal pad and the palmar pad may be formed from a material, such as polyurethanes, elastomers, etc. 
     In some cases, injury to one or more fingers may be caused by age or be one of numerous injuries stained by the user. In these cases, the user may be unable to apply necessary force to the slide to cause the injured finger to extend. Thus, in some implementations, the adjustable finger splint may be designed, such that a third-party (e.g., physical therapist, hand therapist, doctor, surgeon, nurse, or other medical professional) is able to adjust the slide relative to the main body. In these implementations, the slide may include a pull or handle proximate to the front end that the third-party may use to adjust the slide relative to the main body. The main body may also include a grip or other stabilizing portion that the third-party may utilize to substantially maintain the position of the main body when adjusting the position of the slide. In one particular implementation, the main body may be weighted such that when the adjustable finger splint is set or rests on a table or other surface, the main body preserves its position as the palm side is moved. 
     In some cases, the finger splint may also be configured to allow the user or other medical professional to measure the angle of the finger relative to the hand of the user both at rest and during use of the splint. For instance, in some implementations, the adjustable finger splint may include a window such that the user or the medical professional may utilize a protractor or other tool to measure the relative angles between the finger and hand. In other implementations, the protractor may be built into the splint, such as printed along the window, or the main body may include an extended portion that may mirror the position of the finger within the opening of the main body. In still other implementations, the adjustable finger splint may include a dial that may be turned to adjust the position of the slide relative to the main body and also provide or determine the relative angle of the finger and hand. 
       FIG.  1    depicts an embodiment of an adjustable finger splint  100 . The adjustable finger splint  100  may comprise a main body  102 , a slide  104 , a dorsal pad  106 , and a palmar pad  108 , as discussed above. As illustrated, the finger splint  100  may include a front  110  and a back  112 . In the illustrated example, the front  110  is positioned away from the user during use and the back  112 , opposite the front  110 , is positioned proximate to or facing the body of the user during use. 
     As discussed above, the main body may also include an opening or cavity, generally indicated by  114 , configured to receive a finger of the user during treatment or use. When the finger is secured within the finger opening  114 , the user’s finger may be resting on the palmar pad  108 , such that the end of the user’s finger is proximate the front  110  and the palm of the user is proximate the back  112 . The user may then push on a back end  116  of the slide  104 , to cause the slide  104  to move in a direction towards the front  110  of the splint  100 . As the palmar pad  108  is flexible, the inserted finger may force the palmar pad  108  downward such that it bends down to rest atop the slide  104 . The slide  104  may push the palmar pad  108  and the finger of the user upwards as the slide  104  is moved towards the front  110 . As the palmar pad  108  and the finger are extended upward the finger may contact the dorsal pad  106 . The dorsal pad  106  and the main body  102  apply pressure in opposite directions (e.g., upward and downward respectively) on the finger causing the finger to extend and straighten. As the position of the slide  104  relative to the main body  102  may be moved or adjusted to increase or decrease the pressure applied to the end of the finger, the user may set the pressure load based on the discomfort that the user is experiencing (e.g., by increasing the pressure, the effect of the treatment is increased but so is the discomfort). 
     In the illustrated example, both the main body  102  and the slide  104  are substantially rigid, such that the splint  100  may apply opposing pressure on a finger placed within the finger opening  114  of the main body  102 . However, in some situations, direct contact between the substantially rigid material of the main body  102  and slide  104  may result in increased pain levels that exceeds the tolerance thresholds of the individual being treated, even for a short duration. Thus, in the illustrated implementation, the adjustable finger splint  100  may also include the dorsal pad  106  and the palmar pad  108  to increase comfort and reduce pain caused by the finger splint  100  during use. It should be understood that in other implementations, the dorsal pad  106  and the palmar pad  108  may be optional or removable. For instance, the dorsal pad  106  and/or the palmar pad  108  may wear out or occasionally need to be replaced. In these instances, by including a removable dorsal pad  106  and palmar pad  108 , the entire splint  100  does not have to be discarded when the pads  106  and  108  are worn out. In some situations, the thickness and/length of either or both of the dorsal pad  106  or the palmar pad  108  may be adjusted or custom sized to fit the intended user. In these situations, by including removable dorsal pads  106  and palmar pads  108 , the main body  102  and the slide  104  may be stock to reduce manufacturing costs of the splint  100 . 
       FIG.  2    depicts an example left side view of the adjustable finger splint  100  of  FIG.  1    according to some implementations. In the illustrated example, the finger splint  100  again includes two rigid or hard component, the main body  102  and the slide  104 , as well as two pads, the dorsal pad  106  and the palmar pad  108 . In this example, a finger of a user may be placed between the dorsal pad  106  and the palmar pad  108 , such that the finger of the user rests on the front portion of the palmar pad  108 (A) and the palm of the user rests on the rear portion of the palmar pad  108 (B) during use. In this implementation, the main body  104  includes a metacarpophalangeal (MCP) platform  202  that is configured to support the rear portion of the palmar pad  108 (B) and, thereby, maintain the palm of the user in a fixed position during use. In some implementations, a frame  208  may extend upward from the MCP platform  202 . The frame  208  may be configured to support a PIP platform (not shown) over the finger of the user when the splint  100  is in use. The PIP platform may be configured to couple to the Dorsal pad  106  and maintain the Dorsal pad  106  above the finger being treated. In the illustrated example, the MCP platform  202  may be integral to the frame  208 , however, in some implementations the MCP platform  202  and/or frame  208  may be configured to decouple from each other, such that different sized MCP platforms  202  and/or frames  208  may be selected based on the specific finger, anatomical measurements of the injured hand, the characteristics associated with the palmar pad  108  (such as thickness of the padding, material type, number of layers, etc.), and/or the characteristics of the associated with the dorsal pad  106  (e.g., as thickness of the padding, material type, number of layers, etc.). 
     In the current example, the main body  102  may have a slide platform  204  extending between walls of the frame  208 . The slide platform  204  may support the slide  104  during use and include a top surface (not shown) that is included at a predetermined angle relative  206  to the MCP platform  202 . The relative angle of the incline of the slide platform  204  to the MCP platform  202  causes the slide  104  to engage the palmar pad  108  in a manner that lifts the front end of the palmar pad  108  at an angle complementary to the relative angle  206  between the MCP platform  202  and the slide platform  204 , as discussed below with respect to  FIG.  4    in more detail. 
       FIG.  3    depicts an example right side view of the adjustable finger splint  100  with the palm side  104  in initial or loose position of  FIG.  1    according to some implementations. In this example, once the user’s hand is engaged with the splint  100  (e.g., the palm of the user is resting on the rear portion of the palmar pad  108 (B) and the finger being treated is resting on the front portion of the palmar pad  108 (A)), the user may apply forward pressure, generally indicated by arrows  302 , on the slide  104  by pushing on the back end  116  of the slide  104  to cause the slide  104  to move forward (e.g., toward the front end  110  of the splint  100 ) and, thereby, raising the front portion of the palmar pad  108 (A) upwards, as illustrated below with respect to  FIG.  4   . 
     In the illustrated example, the main body  102  may also include a window  304 . The window  304  may allow the user and/or a medical professional to view the position or angle of the finger during treatment. For example, the user and/or a medical professional may utilize a tool (e.g., a protractor) to measure the relative angle of the finger during treatment and, thereby, gage a level of affect or improvement (e.g., relative straightening of the finger) experienced by the user. In some cases, the window  304  may include markings (e.g., degrees) that may be used to measure the relative angle of the finger without the use of additional tools. 
       FIG.  4    depicts an example right side view of the adjustable finger splint  100  of  FIG.  1    with slide  104  in an engaged position according to some implementations. As discussed above with respect to  FIG.  3   , the user may apply forward pressure  302  on the back end  116  of the slide  104  to cause the slide  104  to engage with the front portion of the palmar pad  108 (A). As illustrated when the slide  104  is engaged with the front end of the palmar pad  108 (A), the front end of the palmar pad  108 (A) is raised upward toward the dorsal pad  106 . Thus, in the engaged position, the dorsal pad  106  applies a downward or stabling pressure on the proximal phalanx and the front end of the palmar pad  108 (A) applies an opposite upward pressure on the distal phalanx (or the end of the finger), causing the finger to extend as the MCP joint and the PIP joint are straightened. By maintaining force on the joint at maximum extension, the contracted tissues are elongated and mobility is restored. However, by allowing the user to apply the pressure  302  to the slide  104 , the user is able to control the amount of time spent applying the treatment and, in some situations, to remove the hand from the splint  100 , allowing the user use of the hand and a break from the treatment. 
     As discussed above, the main body  102  may include a slide platform  204  that has an incline that is at a predetermined angle (not shown) relative to the MCP platform  202 . The relative angle of the incline of the slide platform  204  to the MCP platform  202  causes the slide  104  to engage the palmar pad  108  in a manner that lifts the front end of the palmar pad  108 (A) at an angle complementary to the relative angle between the MCP platform  202  and the slide platform  204 . In the current example, the slide  104  also has a wedge  404  positioned proximate to a front end  406  of the slide  104 . The wedge  404  has a curvature that is configured to cause the finger to straighten as the slide  104  is pushed towards the front end  110 . Thus, in the illustrated implementation, the finger of the user is forced into the extended position in part due to the relative angle between the incline of the top surface of the slide platform  204  and the MCP platform and in part based on the curvature of the wedge  404 . The radius of the curvature of the wedge  404  is calibrated to maintain the DIP joint in a neutral position throughout the range of extension of the slide  104 . 
     In the illustrated example, the main body  102  may also include a measuring device  408 . As discussed above, the splint  100  may include a window to allow the user and/or a medical professional to view the position or angle of the finger during treatment. In this example, the splint  100  may include a measuring device  408  that may indicate the angle or straightness of the finger being treated. For example, the measuring device  408  may be mechanically coupled to a component that is adjusted based on contact or position of the slide  104 . In this example, the measuring device  408  may rotate to provide an indication of the angle or straightness of the finger being treated as the slide  104  is adjusted. It should be understood that in other examples, the measuring device  408  may take other forms. 
       FIG.  5    depicts an example rear view of the adjustable finger splint  100  of  FIG.  1    according to some implementations. As discussed above, the main body  102  includes a frame  208  that supports a PIP platform  502 . The frame  208  and the PIP platform  502  of the main body  102  forms a finger opening  114  to receive a finger of the user as discussed above. In the illustrated example, the dorsal pad  106  may be secured or adhered to the PIP platform  502  and the palmar pad  108  may be secured or adhered to the MCP platform  202  as shown. For example, various types of adhesive may be used to affix the dorsal pad  106  to the underside of the PIP platform  502  and the palmar pad  108  to the top surface of the MCP platform  202 . 
     In the illustrated example, the back end  116  of the finger splint  104  may be textured or patterned to allow for increased friction when the user pushes or applies pressure to the back end  116  of the slide  104 . It should be understood, that the finger splint  100  may be operated by the user with one hand. For example, the user may grip a front (not shown) of the MCP platform  202  using healthy fingers, generally at locations  504  and/or  506 , while engaging the back end  116  of the slide  104  using the thumb. 
       FIG.  6    depicts another example rear view of the adjustable finger splint  100  of  FIG.  1    according to some implementations. In the current example, the dorsal pad  106  and the palmar pad  108  have been removed from the main body  102 . In some situations, the pads  106  and/or  108  may wear at a faster rate than the main body  102  and/or the slide  104  or the thickness of the dorsal pad  106  and/or the palmar pad  108  may be selected or adjusted based on the needs of the individual being treated. For instance, some individuals may have hands thinner than others. These individuals may require the use of larger dorsal pads  106  and/or palmar pads  108 . Thus, such as in the illustrated example, in some implementations, the dorsal pad  106  and/or the palmar pad  108  may releasably couple to the main body  102 . 
     In the current example, the dorsal pad  106  may include one or more coupling components  602  that extend upwards from a top surface  604  of the body of the dorsal pad  106 , such that the coupling components  602  may be received by corresponding receptacles (not shown) over the finger opening  114  along a bottom surface  610  of the PIP platform  502 . In some implementations, the dorsal pad  106  may include two coupling components, such as left coupling components  602 (A) and right coupling components  602 (B). In some examples, the coupling components  602  may include a locking or mating member that may secure the dorsal pad  106  to the main body  102 . In some implementations, such as the illustrated example, the dorsal pad  106  may be secured by friction between the coupling components  602  and the corresponding receptacles within the bottom surface  610  of the PIP platform  502 . In some implementations, the bottom surface of the dorsal pad  106  may be contoured to receive the top surface of the finger of the user to provide increased comfort. In some implementations the dorsal pad  106  may be coupled in a manner that allows its position to be adjusted for the fit and comfort of the user, as will be discussed in more detail below. 
     The palmar pad  108  may also include one or more coupling components  606  that extend downward from a bottom surface  608  of the body of the palmar pad  108 . For example, the MCP platform  202  may include a receptacle  612  for receiving the coupling component  606 . In this example, the receptacle  612  may open to the back  112  of the MCP platform  202  such that the coupling component  606  may be pushed or slide into the receptacle  612  from the back  112  of the splint  100 . In some instances, the receptacle  612  may extend along at least a portion of the MCP platform  202 , such that the front of the coupling component  606  abuts a back surface (not shown) of the receptacle  612  to resist forward movement caused by pressure on the back end  116  of the slide  104  and maintain the palmar pad  108  on the MCP platform  202 . In these examples, the coupling component  606  and receptacle  612  may have corresponding angled walls such that the coupling component  606  may resist upward movement caused by pressure of the slide  104  on the front end of the palmar pad  108 , as discussed above. 
       FIG.  7    depicts an example front view of the adjustable finger splint  100  of  FIG.  1    according to some implementations. In the current example, the slide  104  is at rest or has not been engaged with the palmar pad  108 . In this example, the main body  102  includes the finger opening  114  to receive the finger of the user prior to engaging the slide  104  with the palmar pad  108 . In the illustrated implementation, a front of the MCP platform  202  is visible. In this illustrated implementation and as discussed above, the user may place one or more healthy fingers at locations  504  and  506  to provide apply a backwards pressure when the user pushes the slide  104  forward. In some cases, the locations  504  and  506  may include a texture or grip that provides increased frictions and allows the user to more easily apply the backwards pressure on the MCP platform  202 . 
       FIG.  8    depicts an example top view of the adjustable finger splint  100  of  FIG.  1    according to some implementations. In the current example, the dorsal pad  106  and the palmar pad  108  are in place and the slide  104  is currently in the at rest position. As shown, the back portion of the palmar pad  108 (A) may cover the surface of the MCP platform  202  and the palmar pad  108  may then extend through and out of the main body  102 , as illustrated by the front end of the palmar pad  108 (A). As the palmar pad  108  is formed from a flexible material the front end of the palmar pad  108 (A) may flex upwards when in contract with the slide  104 . 
     The dorsal pad  106  is secured to the bottom surface or underside of the PIP platform  502 . In the current example, the dorsal pad  106  may extend past a front or rear edge of the PIP platform  502  to allow the user or other individual to pinch and remove the dorsal pad  106  from the main body  102  by pulling downward on the dorsal pad  106 . 
       FIG.  9    depicts an example bottom view of the adjustable finger splint  100  of  FIG.  1    according to some implementations. As illustrated, the slide  104  is resting on the slide platform  204 . As discussed above, the slide platform  204  has a top surface (e.g., the surface in contact with the slide  104  and not shown) that includes an incline at a predetermine angle relative to the MCP platform  202 . 
       FIG.  10    depicts an example top view  1002 , side view  1004 , and bottom view  1006  of the slide  104  of  FIG.  1    according to some implementations. As discussed above, in some implementations, the slide  104  may be releasably coupled to the main body  102  of  FIGS.  1 - 9   , such that the slide  104  may be removed or separated from the main body  102  when not in use and, thus, allow for the adjustable finger splint  100  to be more easily stored or carried. In the illustrated example, the slide  104  includes a slide rail  1016  and a wedge  404  having a predefined curvature  1008 . The curvature  1008  of the wedge  404  causes the finger to gradually extend or straighten as the slide  104  is moved in a direction towards the front end  110  of the splint  100 . The curvature  1008  having a radius of between approximately 3.0 centimeters (cm) and 5.0 cm. In one particular example, the radius of the curvature  1008  may be 4.0 cm. 
     The wedge  404  also includes a lip or edge  1010  that forms a groove or recessed portion  1012  along either side of the wedge  404 . The main body may include two locking members that may be received into the recessed portion  1012  via an opening  1014  on either side of the slide  104 . In some examples, the slide  104  may be coupled with the main body  102  by placing the locking members into the recessed portion  1012 . Then when the palmar pad  108  may be coupled to the main body  102  over the slide  104 , such that the palmar pad  108  prevents the slide  104  from decoupling from the main body  102 . In this manner, the slide  104  is less likely to decouple or become lost. 
     In some implementations, the length (e.g., the distance between a back end  116  and a front end  406 ) of the slide  104  may be between approximately 9.0 cm and 10 cm. In one particular example, the length of the slide  104  may be 10.3 cm. The wedge  404  may also have a length that is between one-third and one-fourth the length of the slide  104  and the slide rail  1016  may have length between two-third and three-fourths of the length of the slide  104 . For example, the wedge  404  may be between 3.0 cm and 4.0 cm long and the slide rail  1016  may be between 6.0 cm and 7.0 cm. In one particular example, the wedge  404  may have a length of 4.6 cm and the slide rail may have a length of 6.4 cm. The slide rail  1016  may also have a height of between approximately 1.0 cm and 2.0 cm and a width between approximately 1.5 cm and 2.5 cm. The wedge  404  may have a height of between approximately 2.0 cm and 3.0 cm and a width between approximately 1.5 cm and 2.5 cm. In some cases, the width of the slide rail  1016  and the wedge  404  may be the same or equal to the size of the slide opening  1102  in the main body  102 , as discussed below with respect to  FIG.  11   . 
     In some examples, the slide  104  may be formed as a single component or unit. The slide  104  may be formed from a rigid material, such as various plastics, polymers, polyethylene terephthalate, among others. In some cases, the slide  104  may have a shore D average hardness rating of between approximately 75 and 85. 
     In the current example, the slide  104  is illustrated as removed from the main body  102 . However, it should be understood in other alternative implementations, the finger splint  100  may be configured to prevent loss of the independent components of the splint  100  and, thus the palm side  104  may be movable or adjustable with respect to the main body  102  but affixed (e.g., via a track) to the main body  102 , such that the splint  100  is a single unit. 
       FIG.  11    depicts an example back perspective view of the main body  102  of the adjustable finger splint  100  of  FIG.  1    according to some implementations. As discussed above, the main body  104  includes a MCP platform  202  for providing support for both the palmar pad (not shown) and a palm of the user (not shown), a frame  208  that supports both a PIP platform  502  and the slide platform  204  at opposite ends. For instance, the PIP platform  502  is position above a top surface  1110  of the MCP platform  202  and the slide platform  204  is positioned below a bottom surface of the MCP platform  202 . 
     The frame  208  may form a continuous opening between the PIP platform  502  and the slide platform  204  from the front of the main body  102 . However, the continuous opening may be divided into two segments from the back of the main body  102  by the MCP platform  202 . The two segments of the continuous opening include the finger opening  114  for receiving the finger and a slide opening  1102  for receiving the slide  104  of  FIGS.  1 - 10   . Thus, in the illustrated implementation, the slide opening  1102  may receive or be occupied the slide  104  during use. 
     The MCP platform  202  may include one or more receptacles, such as a receptacle  612  configured to mate or lock with the palmar pad  108  of  FIGS.  1 - 9   . The receptacle  612  may be between approximately 0.5 cm and 3.0 cm long, 0.5 cm and 1.0 cm wide, and 0.2 cm and 0.5 cm deep. The receptacle  612  may also be narrow along the top and wider along the bottom such that the side walls are angled or flanged outward from top to bottom. The flanged walls prevent the palmar pad  108  from dislodging during use as the slide  104  pushes upward on the front end of the palmar pad  108 (A). The receptacle  612  is also open at the top surface such that the palmar pad  108  may include a coupling component that may mate with the receptacle  612  and is integral with the body of the palmar pad  108 , as discussed in more detail below. In some cases, the flange walls may be at an angle of between approximately 50 and 70 degrees. The frame  208  may also include grooves, generally indicated by  1104 (A) and  1104 (B), that may mate with the front portion of the palmar pad  108 . The frame  208  may have an overhang that defines the grooves  1104 . The overhangs may also act to resist upward movement of the palmar pad  108  when the slide  104  is engaged. The grooves  1104  may also help resist any forward movement of the palmar pad  108 . 
     The PIP platform  502  includes a bottom surface that also includes one or more receptacles, such as receptacles  1106 (A) and  1106 (B). The receptacles  1106  may run the full length of the PIP platform  502  or may only run a partial length of the PIP platform  502 . For instance, the receptacles  1104  may be between approximately 1.0 cm and 3.0 cm long, 0.5 cm and 1.5 cm wide, and 0.5 cm and 1.0 cm deep. In some cases, the length of the receptacles  1106  may be longer than the length of the coupling components of the dorsal pad  106  such that the dorsal pad  106  may be able to slide or adjust as the slide  104  is engaged with the palmar pad  108 , as will be discussed in more detail below. 
     The slide platform  204  may include a top surface  1108  that is at an incline relative to the top surface  1108  of the MCP platform  202 . In some cases, the include may be at an angle of between approximately 5.0 and 15.0 degrees. The incline of the top surface  1108  causes the slide  104  to impact the front end of the palmar pad  108 (A) at an angle that gradually extends or straightens the finger through zero degrees of flexion and into the range of hyperextension. 
     In some examples, the main body  102  may be formed as a single component or unit. The main body  102  may be formed from a rigid material, such as various plastics, polymers, polyethylene terephthalate, among others. In some cases, the main body  102  may have a hardness rating of between approximately shore D average hardness rating of between approximately 75 and 85. 
       FIG.  12    depicts an example partial-front-partial-bottom view of the main body  102  of the adjustable finger splint  100  of  FIG.  1    according to some implementations. In the illustrated example, the receptacles  1106 (A) and  1106 (B) for receiving the coupling components of the dorsal pad  106  (not shown) are visible along the bottom surface of the PIP platform  502 . The frame  208  may also support slide locking members, generally indicated by  1202 (A) and  1202 (B), within the space of the continues opening  1204 . As discussed above, the opening  1204  is continuous along the lengths of the main body  102  from the front but divided between the finger opening  114  and the slide opening  1102  from the back by the MCP platform  202 . Thus, from the current partial-front view of the main body  102 , the opening  1204  runs the full length between the PIP platform  502  and the slide platform  204  as shown. 
       FIG.  13    depicts an example back view of the main body  102  of the adjustable finger splint  100  of  FIG.  1    according to some implementations. In the current illustration, the continuous opening  1204  is defined by the frame  208 , the slide platform  204 , and the PIP platform  502  and is divided into two segments, finger opening  114  and the slide opening  1102  by the MCP platform  202 . In the current implementation, the continuous opening  1204  may be between approximately 5.0 cm and 6.0 cm tall and 2.0 cm and 3.0 cm wide. Similarly, the finger opening  114  may be between approximately 3.5 cm and 4.5 cm tall and 2.0 cm and 3.0 cm wide and the slide opening  1102  may be between approximately 0.5 cm and 1.5 cm tall and 2.0 cm and 3.0 cm wide. In one particular example, continuous opening  1204  may be approximately 5.2 cm tall and 2.2 cm wide, the finger opening  114  may be approximately 3.8 cm tall and 2. 2.2 cm wide, and the slide opening  1102  may be approximately 0.8 cm tall and 2.2 cm wide. 
     In some cases, the frame  208  may be between approximately 6.5 cm and 7.5 cm long or tall and vary between approximately 3.1 cm and 1.5 cm wide. The PIP platform  502  may be between approximately 2.5 cm and 3.5 cm wide and 2.5 cm and 3.5 cm deep. The PIP platform  502  may also have a thickness of between approximately 0.5 cm and 1.0 cm. Similarly, the slide platform  204  may be between approximately 2.5 cm and 3.5 cm wide and 1.0 cm and 2.0 cm deep. The slide platform  204  may also have a thickness of between approximately 0.1 cm and 0.5 cm. 
       FIG.  14    depicts an example top view of the main body  102  of the adjustable finger splint  100  of  FIG.  1    according to some implementations. In the current illustration, the PIP platform  502  and the MCP platform  202  are visible. As the slide platform  204  extends past the back edge of the PIP platform  502 , a portion of the slide platform  204  is also visible. In the current example, the slide locking members  1202  are also visible. The slide locking members  1202  may be configured to lock or mate with the recessed portion  1012  of the slide  104  (not shown) via the opening  1014  in the bottom portion of the wedge  404 . For instance, the slide  104  may be first placed through the slide opening  1102  from the back of the main body  102 . The wedge  404  of the slide  104  may then be positioned above the slide locking members  1202  to align the opening  1014  with the slide locking members  1202 . Next, the slide  104  may be lowered such the slide locking members  1202  are received by the recessed portion  1012  of the slide  104 . The slide  104  may then adjust with respect to the main body  102  as the slide locking members  1202  move within the recessed portion  1012  relative to the main body  102 . In some cases, the palmar pad  108  (not shown) is then placed over the MCP platform  202  by mating the coupling component of the palmar pad  108  with the receptacle  612 . When in place the palmar pad  108  blocks or prevents the slide  104  from decoupling from the slide locking members  1202  and, thus, from decoupling from the main body  102 . 
     From the illustrated example, it should be understood that the width of the MCP platform  202  is wider than the width of the PIP platform  502 . In some cases, the width of the MCP platform  202  may be between approximately 6.0 cm and 7.0 cm and the length of the MCP platform  202  may be between approximately 3.0 cm and 4.0 cm. The MCP platform  202  may also have a thickness that varies from back to front. For example, the thickness at the back of the MCP platform  202  may be between approximately 1.8 cm and 2.2 cm and the thickness at the front of the MCP platform  202  may be between approximately 0.2 cm and 0.7 cm. 
       FIG.  15    depicts an example bottom view of the main body  102  of the adjustable finger splint  100  of  FIG.  1    according to some implementations. In the current illustration, the slide platform  204  and the MCP platform  202  are visible. As the PIP platform  502  extends past the front edge of the slide platform  204 , a portion of the PIP platform  502  is also visible. In the current example, the slide locking members  1202  are also visible. As discussed above, the slide locking members  1202  may be configured to lock or mate with the recessed portion  1012  of the slide  104  (not shown) via the opening  1014  in the bottom portion of the wedge  404 . The receptacles  1106 (A) and  1106 (B) for receiving the coupling components of the dorsal pad  106  (not shown) are also visible. In some cases, the receptacles  1106  may be approximately 0.2 cm from the edge front edge of the main body  102 , approximately 0.2 cm from the back edge of the main body  102 , and approximately 0.2 cm from either side wall of the frame  208  of the main body  102 . 
       FIG.  16    depicts an example side view of a two-part main body  102  of the adjustable finger splint  100  of  FIG.  1    according to some implementations. In the above examples, the MCP platform  202  and the frame  208  may be integrally coupled or formed as a single component. However, in some cases, the MCP platform  202  may be formed as a separate component from the frame  208  and configured to releasably couple to the frame  208 . For example, the palm of a specific user may be usually small or large and require a different sized MCP platform  202  for support. Alternatively, the user’s finger may be too large to fit through the opening in the frame  208  while the MCP platform  202  is attached. In these examples, the MCP platform  202  may be selected to fit the individual user and then coupled to the frame  208 . In the current example, the frame  208  may include male connector components  1602  and the MCP platform  202  includes female connector components. However, it should be understood that, in some implementations, the MCP platform  202  may include the male connectors and the frame  208  may include the female connectors. 
       FIG.  17    depicts an example bottom view  1702  and a side view  1704  of the dorsal pad  106  of the adjustable finger splint  100  of  FIG.  1    according to some implementations. In the current example, the dorsal pad  106  includes two coupling components  602 (A) and  602 (B) for securing the dorsal pad  106  to the PIP platform  502  of the main body  102  (not shown) of the splint  100 . In other implementations, the PIP platform  502  may include any number of coupling components  602 , such as one or three coupling components. 
     The dorsal pad  106  may be between approximately 0.5 cm and 1.5 cm tall, 1.5 cm and 2.5 cm wide, and 2.5 cm and 3.5 cm deep. In one particular example, the dorsal pad  106  may be approximately 0.8 cm tall (not including the extension of the coupling components  602 ), 2.0 cm wide, and 2.5 cm and 3.1 cm deep. In some cases, the coupling components  602  may be less than the full depth of the dorsal pad  106  as illustrated. In these cases, the coupling components  602  may be between approximately 0.2 cm and 0.7 cm tall, 0.2 cm and 0.4 cm wide, and 1.5 cm and 2.5 cm deep. The coupling components  602  may also be shorter than the receptacles  610  of the PIP platform  502  on the main body  102  (not shown), such that the dorsal pad  106  may slide or move relative to the main body  102  and, thereby, adjust for comfort of the user. In some cases, the dorsal pad  106  may be formed from a material, such as various plastics, polyurethanes, rubbers, foams, or other material. In some cases, the dorsal pad  106  may have having a shore A hardness of between approximately 80A and 90A. 
       FIG.  18    depicts an example bottom view of the palmar pad  108  of the adjustable finger splint  100  of  FIG.  1    according to some implementations. As discussed above, the palmar pad  108  includes a front portion  108 (A) and a back portion  108 (B). The front portion  108 (A) may be configured to flex when impacted by the slide  104  (not shown). In various implementing, the back portion  108 (A) may be wider than the front portion  108 (A) and configured to support the palm of the user. For example, the back portion  108 (B) may be between approximately 3.0 cm and 4.0 deep and 6.0 cm and 7.0 cm wide and the front portion  108 (A) may be between approximately 6.0 cm and 7.0 cm deep and 1.5 cm and 2.5 cm wide. Thus, the palmar pad  108  may be between approximately 9.5 cm and 10.5 cm deep. In another example, the palmar pad  108  may be between approximately 8.0 cm and 15 cm deep. 
     In the current example, the front portion  108 (A) and the back portion  108 (B) of the palmar pad  108  may be formed form the same material. However, in other examples, the front portion  108 (A) and the back portion  108 (B) of the palmar pad  108  may be formed from different materials. For instance, the material of the front portion  108 (A) may be less rigid than the material of the back portion  108 (B). In some cases, the palmar pad  108  may be formed from a material, such as various plastics, elastomers, polyurethanes, rubbers, foams, or other material. In some cases, the palmar pad  108  may have having a shore A hardness of between approximately 80A and 98A. 
     In the illustrated example, the palmar pad  108  also includes coupling component  606  for securing the palmar pad  108  to the main body  102  of the splint  100 . In the current example, the coupling component  606  may be between approximately 0.2 cm and 0.5 cm tall, 0.5 cm and 1.0 cm wide, and 0.8 cm and 2.5 cm deep. 
     In some implementations, the main body  102  may also include grooves  1104  along the frame  208 . In these examples, the palmar pad  108  may include a mating surfaces  1802 (A) and  1802 (B) to contact or be received within the grooves  1104 . The contact between the mating surfaces  1802  and the grooves  1104  together with the coupling component  606  may prevent forward motion of the palmar pad  108  with respect to the main body  102  of the splint  100  during use. 
       FIG.  19    depicts another example bottom view of the palmar pad  108  of the adjustable finger splint  100  of  FIG.  1    according to some implementations. Similar, to the implementation illustrated in  FIG.  18   , the current palmar pad  108  includes a front portion  108 (A) and a wider back portion  108 (B). In the current example, the palmar pad  108  also includes multiple coupling components  612 . As illustrated, it should be understood that the length and/or width of each of the individual coupling components  606  may vary with respect to each other or across implementations. 
       FIG.  20    depicts an example side view of the palmar pad  108  of the adjustable finger splint  100  of  FIG.  1    according to some implementations. In the current example, both portions (e.g., the front portion  108 (A) and the back portion  108 (B)) of the palmar pad  108  may be formed from a single material. In this example, the palmar pad  108  may have a thickness that may be between approximately 0.5 cm and 1.0 cm. In other examples, the thickness of the front portion  108 (A) may vary or differ from the thickness of the back portion  108 (B). For instance, the front portion  108 (A) may be thicker than the back portion  108 (B) as the injured finger may require more padding than the palm of the user. As discussed above, the palmar pad  108  may also include one or more coupling components, such as coupling component  606 . 
       FIG.  21    depicts another example side view of the palmar pad  108  of the adjustable finger splint  100  of  FIG.  1    according to some implementations. In this example, the palmar pad  108  may be formed two layers, a top layer  2102  and a bottom layer  2104 . For instance, the palmar pad  108  may require some rigidity or hardness to prevent the slide  104  (not shown) from puncturing or damaging the palmar pad  108  when the palmar pad  108  is impacted by the wedge  404  of the slide  104 . At the same time, the palmar pad  108  may be configured to provide a desired level of flexibility to reduce pain on the finger when the splint  100  is in use. Thus, in the current example, the top layer  2102  may be formed from a first material and the bottom layer  2104  may be formed from a second material. In some cases, the second material may be harder than the first material. For example, the first material may be a plastic, polyurethanes, elastomers, or other material having a Shore A hardness between approximately 80 A and 90 A and the second material may also be a plastic, polyurethanes, elastomers, or other material having a hardness between approximately 90 A and 100 A. 
       FIG.  22    depicts another example perspective view of the palmar pad  108  of the adjustable finger splint  100  of  FIG.  1    according to some implementations. As discussed above, the palmar pad  108  may be formed from two materials, a more flexible material and a more rigid material. In this example, the rigid material may be formed an interior layer  2202  that provides support for the back end of the palmar pad  108 (B) to provide support for the palm of the user and some rigidity to the overall pad  108 . The current example, also includes an exterior layer  2204  that runs along the top and bottom of the interior layer  2202  within the back end of the palmar pad  108 (A) and forms the entirety of the front end of the palmar pad  108 (A). In this example, the interior layer may be formed from the first material and the exterior layer may be formed from the second material. 
     In the illustrated example, the front end of the palmar pad  108 (A) or the finger portion of the palmar pad  108  may include notches, generally indicated by  2206 , along the bottom surface of the pad  108 . The notches  2206  may be used to secure the palmar pad  108  to the slide  104  and to assist in maintain the palmar pad  108  in contact and in a desired alignment with the slide  104 . In the current example, the palmar pad  108  includes three notches  2206 , however, it should be understood that any number of notches  2206  may be implemented. In some cases, the notches  2206  may also add thickness to the palmar pad  108  and increase comfort while maintaining desired flexibility. 
       FIG.  23    depicts another example back view of the palmar pad  108  of the adjustable finger splint  100  of  FIG.  1    according to some implementations. In the current example, the palmar pad  108  includes two coupling components  606  and multiple notches  2206  for coupling the palmar pad  108  to both the main body  102  and the slide  104  (not shown), as discussed above. 
       FIG.  24    depicts another example side view of the palmar pad  108  of the adjustable finger splint  100  of  FIG.  1    according to some implementations. In the current example, again the palmar pad  108  includes an interior layer  2202  and an exterior layer  2204 . The notches  2206  are also shown for coupling the palmar pad  108  to the slide  104  (not shown). 
       FIG.  25    depicts an example perspective view of a main body  102  of the adjustable finger splint  100  of  FIG.  1    with an adjustable PIP platform  502  in a closed position according to some implementations. In some cases, the user’s finger may be severely injured or bent. In these cases, the user may be unable to push the finger through the finger opening  114  if the PIP platform  502  is affixed to the frame  208 . Thus, in the illustrated example, the PIP platform  502  may be movable between a closed position and an open position. 
     In the illustrated example, the PIP platform  502  may be coupled to the frame  208  via hinges, generally indicated by  2502 , such that the PIP platform  502  may open upward from the frame  208 . The PIP platform  502  may also be locked or held in place via locking platform  2504 . The locking platform  2504  may also be coupled to the frame  208  via mating component  2506 . The PIP platform  502  may then be released from the closed position by disengaging the locking platform  2504 , as will be discussed in more detail below with respect to  FIG.  26   . 
       FIG.  26    depicts an example perspective view of a main body  102  of the adjustable finger splint  100  of  FIG.  25    with the adjustable PIP platform  502  in an open position according to some implementations. In the current example, the locking platform  2504  has been pushed up and towards the front end  110  of the splint  100 , such that the locking platform  2504  no longer obstructs the opening  114 . For instance, when in the closed position, a locking member  2602  of may extend outward and under the locking platform  2504  and releasably couple with the mating component  2206 . For instance, when the locking platform  2504  is moved downward and towards the front end  110  of the splint  100 , the locking platform  2504  prevents the PIP platform  502  from moving during use. In one specific example, a bolt couples  502  to  208  creating a hinged door so the platform  502  and dorsal pad (not shown) can be rotated up and away from the finger. A shorter bolt may also couple  2204  to  2502  creating a latch. After the finger is placed in the device, the door is closed and the latch may be rotated to couple to the mating component  2506 . 
     In the current example, the PIP platform  502  is shown as a hinged component, however, it should be understood that in other examples, the PIP platform  502  may be configured to slide along a groove in the frame  208  between and the open and closed positions. It should also be understood that various other types of locking platforms, mechanisms, or members may be used. In one specific example, the PIP platform  502  may be completely removable form the frame  208 . 
       FIG.  27    depicts an example perspective view of an adjustable finger splint  100  usable by a third-party according to some implementations. In some cases, injury to one or more fingers may be caused by age or be one of numerous injuries stained by the user. In these cases, the user may be unable to apply necessary force to the slide  104  to cause the injured finger to extend. Thus, in some implementations, the adjustable finger splint  100  may be designed, such that a third-party (e.g., physical therapist, hand therapist, doctor, surgeon, nurse, or other medical professional) is able to adjust the slide  104  relative to the main body  102 . In these implementations, the slide  104  may include a pull or handle  2702  proximate to the front end  406  of the slide  104 , such that the third-party may use to adjust the slide  104  relative to the main body  102  by pulling on the handle  2702 . The main body  102  may also include a grip or other stabilizing portion  2704  that the third-party may utilize to substantially maintain the position of the main body  102  when adjusting the position of the slide  104 . In one particular implementation, the main body  102  may be weighted such that when the adjustable finger splint  100  is set or rests on a table or other surface, the main body preserves its position as the palm side is moved. 
       FIG.  28    depicts an example side view of the adjustable finger splint  100  of  FIG.  27    according to some implementations. As illustrated, the handle  2702  of the slide  104  may extend to both the right and left of the wedge  404 . Thus, a third-party that is either right or left handed may utilize the handle  2702 . In some cases, the handle  2702  may decoupled from the slide  104 , such that the slide  104  may be placed through the frame  208  from the back of the splint  100  and then the handle  2702  may be attached from the front. 
       FIG.  29 A  depicts an example front view and  FIG.  29 B  depicts an example back view of the adjustable finger splint  100  of  FIG.  27    according to some implementations. As discussed above, the slide  104  may include the handle  2702  to assist a third-party individual in operating the finger splint  100 . In this example, the handle  2702  extends to both the right and left of the wedge  404 . In the current example, the extensions of the handle  2702  are less wide than the width of the MCP platform  202 . However, in other examples, it should be understood that the length and width of the extensions of the handle  2702  may vary, for instance, the extensions may extend past the outer edges of the MCP platform  202 . 
     The main body  102  also includes a stabilizing portion  2704  that may be gripped by the third-party individual when pulling on the handle  2702 . In the current example, the stabilizing portion  2704  is shown as a rounded handle. But it should be understood, that the stabilizing portion  2704  may take other forms, such as a gripped handle, weighted portion that may rest on a table or other surface, etc. 
       FIG.  30    depicts an example perspective view of the slide of the adjustable finger splint of  FIG.  27    according to some implementations. As discussed above, the slide  104  may include the handle  2702  to assist a third-party individual in operating the finger splint  100 . In this example, the handle  2702  extends to both the right and left of the wedge  404 . In the current example, the extensions of the handle  2702  are less wide than the width of the MCP platform  202 . However, in other examples, it should be understood that the length and width of the extensions of the handle  2702  may vary, for instance, the extensions may extend past the outer edges of the MCP platform  202 . 
       FIG.  31    depicts an embodiment of an adjustable finger splint  100 . The adjustable finger splint  100  may comprise a main body  102 , a slide  104 , a dorsal pad  106 , and a palmar pad  108 , as discussed above. As illustrated, the slide  104  and the palmar pad  108  are movable relative to the main body  102  and the dorsal pad  106 , such that as the slider is moved in a direction indicated by  110 , the finger of the user is increasingly straightened relative to the hand. In this manner, the user may control the amount of pressure applied based on the user’s comfort level. 
       FIG.  32    depicts the main body  102 , the slide  104 , the dorsal pad  106 , and the palmar pad  108  separated from one another. As shown in  FIG.  32   , the main body  102  can have a frame  208  including a slide platform  204 , a MCP platform  202 , and a PIP platform  502 . The slide  104  can comprise a wedge  404  and a slide rail  1016 . 
     The slide platform  204  can be positioned at or near the bottom of the frame  208  and can extend along at least a portion of the main body. In some embodiments, the slide platform  204  can be coupled with the frame  208  via an adjustable hinge  3202 , such that the angle of the slide platform  204  relative to the frame  208  can be adjusted. As will be discussed below, the slide rail  1016  of the slide  104  can slide along the slide platform  204  during use. 
     The MCP platform  202  can extend out behind the frame  208  at a position above the height of the slide platform  204 , such that at least a portion of the slide rail  1016  of the slide  104  can fit between the top of the slide platform  204  and bottom of the MCP platform  202 , as discussed above. In some examples, at least a portion the MCP platform  202 , such as an MCP extension  3204  protruding downward from the MCP platform  202 , can contact the slide rail  1016  of the slide  104  during use, thereby helping to keep the slide  104  in place within the main body  102 . As will be discussed below, a user’s MCP joint can contact the top of the MCP platform  202  during use. 
     The PIP platform  502  can be positioned at the top of or supported by the frame  208 . The dorsal pad  106  can be coupled to the underside of the PIP platform  502 , as discussed above. The PIP platform  502  and dorsal pad  106  can be positioned above the height of the MCP platform  202 , such that a user’s finger can be inserted into a space between the MCP platform  202  and the dorsal pad  106 . During use, the top of a user’s PIP joint can contact the underside of the dorsal pad  106  when the user’s finger is inserted into the adjustable finger splint  100 . 
     During use, the slide rail  1016  of the slide  104  can be moved along the slide platform  204  of the main body  102 , such that the slide  104  is movable relative to the main body  102 . In some examples, the slide rail  1016  and the slide platform  204  can be slideably coupled with each other, such as by having a protrusion in one of the slide rail  1016  or the slide platform  204  notched into a groove that extends along the other one of the slide rail  1016  or the slide platform  204 . 
     The wedge  404  can be coupled to the top of the slide rail  1016 . However, in the current example, the wedge  404  may be releasably coupled to the slide rail  1016 , such that wedges  404  having different curvatures may be used in conjunction of the splint  100  to treat an injured finger. The top of the wedge  404  can be shaped with a curvature, as discussed above. The slide  104  can be moved along the slide platform  204  to adjust the position of the wedge  404  relative to a finger inserted into the adjustable finger split  100 . 
     In this example, the palmar pad  108  rests on the wedge  404  or be coupled with the wedge  404 , such that the bottom of a user’s DIP joint contacts the palmar pad  108  above the wedge  404  during use. The palmar pad  108  can slide along the curvature of the top of the wedge  404 , such that the palmar pad  108  can maintain contact with a user’s DIP joint as the wedge  404  moves underneath the palmar pad  108 . In some examples, the palmar pad  108  can be separate from the wedge  404  and be held in place against the wedge  404  by the presence of the user’s finger. In other examples, the palmar pad  108  can be slideably coupled with the wedge  404 , such as by having a protrusion in one of the palmar pad  108  or wedge  404  notched into a groove that extends along the other one of the palmar pad  108  or wedge  404 . 
     Although in some embodiments the elements of the PIP platform  502  can be fixed in position on the frame  208 , in other embodiments components of the PIP platform  502  can be moveable and/or openable to make it easier to insert a finger into the adjustable finger splint  100  or to remove a finger from the adjustable finger splint  100 . 
     Additionally, the main body  102 , the slide  104 , the dorsal pad  106 , and the palmar pad  108  are shown as releasable components of the adjustable finger splint  100 . However, it should be understood that one or more of the components  102 - 108  may be formed as a single component. For example, the palmar pad  108  may be secured to the slide  104  via a tongue and groove coupling, to allow the palmar pad  108  to move independently from the slide  104  along the length of the curvature of the wedge  404 . In another example, the slide  104  may be coupled over the slide platform  204  in a manner that the slide  104  may move independently along the length of the slide platform  204  during use but remain coupled when a finger is not engaged with the finger splint  100 . 
     As shown in  FIGS.  33 A- 33 F , in some of these moveable and/or openable embodiments, the PIP platform  502  can have a moveable panel  3302 , one or more buckle elements  3304 , and a latch  3306 . The moveable panel  3302  and the one or more buckle elements  3304  can be hingeably coupled with the frame  208 . The latch  3306  can be on at least one of the buckle elements  3304  and be configured to selectively lock the buckle elements  3304  over the moveable panel  3302 . The dorsal pad  106  can be coupled with the underside of the moveable panel, as shown below. 
     When a finger is to be inserted into the adjustable finger splint  100 , the buckle elements  3304  and moveable panel  3302  can be angled upward, as shown in  FIGS.  33 A and  33 B . The PIP platform  502  can thus be opened relative to the MCP platform  202  and/or slide  104 , thereby providing more room for a finger to be inserted into the adjustable finger splint  100 , as shown in the side view of  FIG.  33 B . For example, an injured finger with extreme flexion that cannot easily be straightened to fit into the adjustable finger split  100  can be given more room by opening the PIP platform  502  and angling the moveable panel  3302 . 
     To close the PIP platform  502 , the moveable panel  3302  can be lowered as shown in  FIG.  33 C , and the buckle elements  3304  can then be lowered over the moveable panel  3302  as shown in  FIGS.  33 D- 33 E . The latch  3306  than then be used to lock the buckle elements  3304  over the moveable panel  3302  as shown in  FIG.  33 F . 
     When the finger is to be removed, the latch  3306  can be released, such as by releasing a tab on the latch  3306 , thereby freeing the buckle elements  3304  and moveable panel  3302  to again be angled upward as shown in  FIG.  33 B  such that there is more room to remove a finger from the adjustable finger splint  100 . 
     It should be understood that the examples illustrated in  FIGS.  33 A- 33 F , a buckle element  3304  is shown to allow the bent finger of a user to be inserted into the adjustable finger splint  100 . However, it should be understood that other types of latches, locks, joints, and openings may be used to allow a bent finger sufficient access to the opening in the adjustable finger splint  100 . 
       FIGS.  34 A and  34 B  depicts the adjustable finger splint  100  in use. As shown in  FIG.  34 A , the wedge  404  of the slide  104  can be retracted at least partially into the frame  208  by sliding the slide rail  1016  along the slide platform  204  of the main body  102 . A user’s finger can then be placed into the adjustable finger splint  100  such that the bottom of the finger’s MCP joint contacts the MCP platform  202 , the top of the finger’s PIP joint contacts the dorsal pad  106  underneath the PIP platform  502 , and the bottom of the finger’s DIP joint contacts the palmar pad  108  above the wedge  404 . As discussed above with respect to  FIGS.  33 A- 33 F , in some embodiments the PIP platform  502  can be opened and/or angled to assist with insertion of the finger, followed by closing and locking the PIP platform  502  after the finger is in place. 
     After a user’s finger is in place within the adjustable finger splint  100  with the slide  104  retracted, as shown in  FIG.  4 A , the slide  104  can be distally extended by sliding the slide rail  212  along the slide platform  204 , as shown in  FIG.  4 B . As the slide  104  is distally extended, the curvature of the wedge  404  can press the finger’s DIP joint upward by increasing amounts as the slide  104  slides farther along the slide platform  204 . The palmar pad  108  can also move along the top of the wedge  404  and change its incident angle as the slide  104  is distally extended, with the curvature of the wedge  404  causing the angle and position of the palmar pad  108  to match the angle and position of the finger’s DIP joint as the wedge  404  moves underneath the palmar pad  108 . 
     In some examples, the main body  102  and/or slide  104  can have a locking mechanism, such as a latch, buckle, or ratchet, that can at least temporarily hold the slide  104  in place relative to the main body  102  once it has been distally extended and positioned for treatment of an inserted finger. In other examples, the force of an inserted finger pressed against the palmar pad  108  and wedge  404  and/or the contact of the slide rail  1016  against the MCP extension  3204  or other portion of the MCP platform  202  can help maintain the slide  104  in place during treatment. 
     As shown in  FIG.  35   , the slide  104  can be extended from the main body  102  by squeezing the back of the slide rail  1016  and the front of the slide platform  204 , thereby pushing the slide  104  along the slide platform  204 . Such a squeezing motion provide forces in opposing directions that are substantially parallel to the finger within the adjustable finger splint  100 . Such opposing parallel forces can have less impact on an injured finger than torque forces introduced by other devices that operate by turning screws to move components. 
     As noted above, in some examples the slide platform  204  can be moveable relative to the rest of the main body  102  via a hinge  3502 , such that the angle of the slide platform  204  and the slide  104  can be adjusted. The angle of the slide  104  can therefore be adjusted in order to treat different injuries of different types and/or severities. For example, in  FIGS.  34 A and  34 B , the slide platform  204  is angled upward so that the slide  104  can be positioned to treat an interphalangeal joint from about 40° flexion to about 10° hyperextension. However, the slide platform  204  can also be positioned to be flat or angled downward to position the slide  104  for treatment of more severely contracted joints. In examples in which the PIP platform  502  can be angled and/or opened, as discussed above with respect to  FIGS.  33 A- 33 F , the PIP platform  502  can be unlatched to allow a finger to be inserted or removed without adjusting the angle of the slide platform  204  and slide  104 . 
       FIGS.  36 A-D  depicts an example views of an adjustable finger splint  100  with adjustable proximal interphalangeal platform  502  according to some implementations. In some situations, the dorsal pad  106  may need to be customized to the individual being treated and/or the shape of the dorsal pad  106  may be adjusted during treatment to gradually allow the injured finger to achieve an extended or straightened position. For example, an injured individual may start treatment with a dorsal pad  106  with an arc similar to that of  FIG.  36 B , reach a mid-way point and continue treatment with dorsal pad  106  of  FIG.  36 C , and then complete the treatment with a dorsal pad of  FIG.  36 D . Thus, the dorsal pad  106  eventually is substantially horizontal and allows the finger to fully extend at a period of time nearing the completion of treatment. 
     In these examples, the PIP platform  502  is also configured to releasably couple or decouple from the frame  208 . In this example, the PIP platform  502  may include mating components  3602  configured to mate with paired mating components  3604  on the frame  208 . For instance, a user may pinch or apply inward pressure on the bottom of the PIP platform  502 , align the mating components  3202  and  3204 , and release to position the PIP platform  502  with the frame  208 . In some cases, the relative position of the PIP platform  502  with the frame  208  may be adjusted based on characteristics of the finger being treated. For example, the PIP platform may be tilted forward or backward relative to the frame  208 . As one illustrative example, the PIP platform  502  may be initially tilted forward and adjusted backward toward an upright configuration as treatment progresses. 
       FIG.  37    depicts an example side view of an adjustable finger splint  100  with adjustable proximal interphalangeal platform  502  according to some implementations. In the illustrate example, the frame  208  is again releasably coupled to the PIP platform  502 . However, in this example the PIP platform  502  may slide in a lock with the frame  508  using the mating components  3702  and  3704 . 
       FIG.  38    depicts an example perspective view of an adjustable finger splint  100  with ratchet locking system  3802  according to some implementations. In this example, the slider  104  includes female ratchet components  3802 (A) and the slider platform  204  of the main body  102  includes mating male ratchet components  3802 (B). In this example, as the user move the slider  104  forward, the female ratchet components  3802 (A) move over the male ratchet components  3802 (B) due to the force applied by the user. When the user releases the slider  104  the female ratchet components  3802 (A) aligned with the male ratchet components  3802 (B) mate and lock together. When mated, the ratchet locking system  3802  is able to provide additional friction to hold the slider  104  at the desired position relative to the main body  102  to better maintain desired pressure on the injured finger. 
     It should be understood, that while the current example includes a ratchet system  3802 , other types of locking systems may be utilized, such as a screw based system, lever based system, or crank based system, and the exact position of the locking system may be move, for example place along the inner surface of the walls of the frame  208  rather than along the top surface of the slider platform  204 . 
       FIG.  39    depicts an example perspective view of an adjustable finger splint  100  with a two-part  108 (A) and  108 (B) palmar pad  108  and guided slide  104  according to some implementations. In the current example, the palmar pad  108  is divided into two parts, the front portion  108 (A) and rear portion  108 (B). The front portion  108 (A) is coupled to the slide  104  and the rear portion  108 (B) is coupled to the MCP platform  202 . In the current example, the slide  104  is also coupled to a guide along the inner walls (not shown) of the frame  208 . For instance, the slide  104  may include a groove  3902  that mates with the guide on the frame  208 . The mated guide and groove  3902  may allow the slide  104  to be maintained along a desired path with respect to the main body  102  during treatment. 
       FIG.  40    depicts an example back view of an adjustable finger splint  100  with a guided slide  104  according to some implementations. As illustrated, the slide  104  includes grooves  3902  along the left-hand and right-hand walls that substantially mirror guides  4002  along the inner walls of the frame  208 . As shown, a gap  4004  may separate the slide  104  from the main body  102  and allow the slide  104  to move relative to the main body  102  while the grooves  3902  and the guides  4002  maintain a path of the slide  104  with respect to the main body  102 . In this example, a top groove  4006  along a top surface of the slide  104  and a corresponding guide  4008  along the main body  102  may also assist in maintaining the path of the slide  104  with that of the main body  102 . In some cases, the top groove  4006  may also the slide  104  to move or slide within or be slideably coupled to the slide  104 . 
       FIG.  41    depicts an example side view of an adjustable finger splint  100  with a two-part palmar pad  108  and guided slide  104  according to some implementations. In the current example, the palmar pad  108  is divided into two parts, the front portion 108(A) and rear portion  108 (B). The front portion  108 (A) is coupled to the slide  104  and the rear portion  108 (B) is coupled to the MCP platform  202 . In the current example, the slide  104  is also coupled to a guide along the inner walls (not shown) of the frame  208 . For instance, the slide  104  may include a groove  3902  that mates with the guide on the frame  208 . The mated guide and groove  3902  may allow the slide  104  to be maintained along a desired path with respect to the main body  102  during treatment. 
       FIG.  42    depicts an example pictorial view of an adjustable finger splint in use according to some implementations. As discussed above with respect to  FIGS.  3  and  4   , the user may apply forward pressure on the back end  116  of the slide  104  to cause the slide  104  to engage an injured finger  4202  with the front portion of the palmar pad  108 (A). In this example, the user  4204  may apply pressure to the slide  104  via the thumb  4206 . In this manner, the user  4204  is able to control the amount of pain caused by the treatment and, in some situations, to remove the hand from the splint  100 , allowing the user  4204  use of the hand and a break from the pain.
