CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application is a continuation-in-part of: 
         [0002]    U.S. patent application Ser. No. 12/462,807 filed 10 Aug. 2009, which carries Applicants&#39; docket no. 18100 B, and is entitled ORTHOPEDIC EXTERNAL FIXATOR AND METHOD OF USE. 
         [0003]    The above referenced document is incorporated by reference herein in its entirety. 
     
    
     BACKGROUND OF THE INVENTION 
       [0004]    1. The Field of the Invention 
         [0005]    The embodiments of the present invention relate primarily to orthopedic apparatuses, sometimes referred to as “fixators”, which organize and/or control positioning at joints or fractures, and/or ranges of motion of juxtaposed bone units at joints. These apparatuses according to the embodiments of the present invention can be organized to impose or to relieve physical stresses associated with the bone units and/or with related ligaments and/or tendons. These apparatuses can be organized to all controlled rotation of the bones at the joint. In one embodiment of the present invention, when squeezed, the apparatus generally produces distraction, when relaxed the apparatus general produces contraction. 
         [0006]    For clarity the embodiments of the present invention are set forth in context of a finger joint. It will, however, be apparent to orthopedic physicians and surgeons and to others that the embodiments of the present invention have comprehensive scope for application to many, many other joints and/or fractures, dislocations, tendon and/or ligament injuries and/or the like. 
         [0007]    2. Description of the Prior Art 
         [0008]    Joint injuries often result in displacement of components of the joint and of bone fragments that have become fractured and dislocated in the injury (Ng, 2009), (Ellis, 2007). 
         [0009]    In the treatment of these injuries it is often required to create traction across a joint so that the components thereof are retained in appropriate relative dispositions during the healing process. It is also advantageous in certain cases to permit gentle controlled movement or relative rotation of the joint, which helps to mold the irregular surfaces and prevents eventual stiffness. 
         [0010]    Numerous innovations for fixators have been provided in the prior art, which will here be described in chronological order to show advancement in the art, and which are incorporated herein by reference thereto. Even though these innovations may be suitable for the individual purposes to which they address, nevertheless, they differ from the present invention. 
         [0011]    (1) U.S. Pat. No. 5,074,865 to Fahmy. 
         [0012]    Referring now to the figures, in which like numerals indicate like parts, and particularly to  FIG. 1 , which is a diagrammatic side elevational view of the prior art distraction apparatus taught by U.S. Pat. No. 5,074,865 to Fahmy, U.S. Pat. No. 5,074,865 issued to Fahmy on Dec. 24, 1991 in U.S. class 606 and subclass 54 teaches a distraction apparatus  10  for maintaining a fractured joint  12  during healing, including a pair of pins  14  for insertion into bone  16  at positions proximal  18  to and distal  20  to the fractured joint  12 , and a pair of stainless steel wire springs  22  that are adjustably attached to the pair of pins  14  to determine and resiliently maintain the relative spacing of pin insertions  24  into the bone  16  thus to retain the components of the fractured joint  12  during the healing process. 
         [0013]    To provide initial distraction, unfortunately, Fahmy requires that the bones must first be manually separated before being held by the apparatus. “The insertion of the pins will take place under general or regional anaesthesia, and then while traction is applied to the finger the thicker of the two springs is attached to and between the pins, its position therealong being determined by location in the first or second grooves close to the finger.” [Emphasis added]. Fahmy at col. 2, lines 20-25. 
         [0014]    To alter the degree of distraction, unfortunately, Fahmy requires that the springs must be manually moved. “The degree of distraction can be initially fixed and subsequently altered easily by moving the two springs closer or spacing them further along the wires, or by adjusting the number of turns of one or both springs between the pins.” [Emphasis added]. 3Fahmy at col. 2, lines 30-34. 
         [0015]    Further, the springs of Fahmy are secured to the pins by a polymer/monomer. “The springs may be secured by adding a small amount of mixed past setting polymer and monomer where the springs are attached to the pins * * * .” [Emphasis added]. Fahmy at col. 2, lines 38-40.

         [0031]    U.S. Pat. No. 5,944,719 issued to Leban on Aug. 31, 1999 in U.S. class 606 and subclass 59 teaches an external fixator for setting fractured bones, which includes a flexible, articulable column including a series of ball and socket members linked by a tensioning cable threaded therethrough. Tightening the cable forces the ball and socket members together and makes the column rigid. There is a mechanism for tightening the cable and keeping the cable in a tightened position to allow the bones to set without moving. A plurality of pivotable pin holders are arranged along the column for attaching to pins inserted into the fractured bones, thus attaching the column to the bones to be set. There is also a mechanism for fixing each pin holder into a rigid position so that there can be no pivoting motion after the proper position of the fixator has been achieved.

         [0035]    U.S. Pat. No. 6,080,153 issued to Mata et al. on Jun. 27, 2000 in U.S. class 606 and subclass 54 teaches an articulation element for the relative positioning of fixation bars or bone pins of an external fixator, which includes a plurality of pairs of jaws. The jaws have on their adjacent faces grooves that form a passage intended to receive a bar or a pin. A spring is interposed between the pairs of jaws. The grooves that form the passage are positioned and arranged so as to have an external opening allowing the bar or bone pin to be snapped in by pressure on it, from the opening of the jaw into the passage, and against the spring force that presses the adjacent faces of the jaws against one another. This force holds the articulation element on the bars or pins before locking of the articulation by way of a clamping shaft.

No. 6,162,223 issued to Orsak et al. on Dec. 19, 2000 in U.S. class 606 and subclass 59 teaches a joint fixator apparatus that conforms to the natural axis of rotation of the joint in question, such as a patient&#39;s wrist or knee, to avoid the possibility of bone fragment displacement and/or fracture reduction. The apparatus includes two fixation rod sections or shaft sections with a spring module therebetween. The spring module is in the form of a flexible coupler that connects to respective ends of the external fixator rod. The module can include a removable clip to restrain the motion of the spring a desired amount, such as before healing takes place. The rods can be used to hold pin clamps that then hold bone pins for attachment to selected bones of the patient, such as above and below a joint or above and below a fracture. The pin clamps can be moved along the rod sections to provide distraction of the joints for a ligamentotaxis effect in reducing the fracture.

         [0000]    United States Patent Application Publication Number US 2004/0044344 A1 published to Winquist et al on Mar. 4, 2004 in U.S. class 606 and subclass 54 teaches an external fixation or adjustable frame structure. A frame structure is retained in any assembled configuration in order to allow final adjustments to be made prior to the final securement of the frame assembly in the precisely desired configuration by closure of each clamp member. In this way, an entire frame assembly is capable of being constructed, adjusted, and readjusted in order to assure each component is oriented in the precisely desired position prior to final closure of the clamping members. In one preferred embodiment, the clamping members employed in the frame structure incorporate friction pins internally mounted in each clamp, and which engage the rod member once this rod is inserted into the jaws of the clamp. In this way, any rod member inserted into the clamping jaws contacts the surface of the jaws and the friction pin preventing the rod member from sliding or moving relative to the clamp. In addition, by incorporating a uniquely constructed, moving wedge plate that is adjustably engageable with any cooperating anchor pin, secure affixation of the mounting member with the anchor pins of any diameter is achieved regardless of the orientation configuration or diameter of the anchor pin.

         [0242]    The at least one first pin  56  is for passing transversely at least into the center of rotation  62  of the head  64  of the first bone unit  32  so as to allow the second bone unit  34  to rotate by flexion and extension (direction of ARROWS  58 ) by allowing the apparatus  30  to pivot around the at least one first pin  56  when the at least one first pin  56  is one first pin  56 . 
         [0243]    D. The Specific Configuration of the Second Attaching Apparatus  46 . 
         [0244]    The second attaching apparatus  46  includes at least one second generally circular-shaped ring  66 . The at least one second generally circular-shaped ring  66  of the second attaching apparatus  46  is for receiving an end  68  of at least one second pin  70 , respectively, passing transversely at least into the second bone unit  34 . 
         [0245]    The at least one second pin  70  is selected from the group consisting of a K-wire and a rod, each having a diameter in a range of 0.045-0.062 inches. 
         [0246]    The at least one second generally circular-shaped ring  66  of the second attaching apparatus  46  is at least a pair of second generally circular-shaped rings  66 . The at least one pair of second generally circular-shaped rings  66  of the second attaching apparatus  46  receives at least a pair of second pins  70 , respectively. 
         [0247]    The at least one pair of second generally circular-shaped rings  66  of the second attaching apparatus  46  are connected to each other by a rod  78 . 
         [0248]    As shown in  FIG. 3 , the apparatus  30  is for positioning on one side  80  of the at least one of the injured bone  36  and the injured joint  38 . Another apparatus  30  is for positioning on the other side  82  of the at least one of the injured bone  36  and the injured joint  38  and receives the other end  84  of the at least one first pin  56 , respectively, and the other end  86  of the at least one second pin  70 , respectively. 
         [0249]    E. The Specific Configuration of the Control Apparatus  48 . 
         [0250]    The control apparatus  48  includes a generally rhombus-shaped ring  88 . The generally rhombus-shaped ring  88  of the control apparatus  48  is straddled by the at least one first generally circular-shaped ring  52  of the first attaching apparatus  44  and the at least one second generally circular-shaped ring  66  of the second attaching apparatus  46 . 
         [0251]    The generally rhombus-shaped ring  88  of the control apparatus  48  has a forward angle  90  and a rearward angle  92 . The at least one second generally circular-shaped ring  66  of the second attaching apparatus  46  extends forwardly from the forward angle  90  of the generally rhombus-shaped ring  88  of the control apparatus  48 . The at least one first generally circular-shaped ring  52  of the first attaching apparatus  44  extends rearwardly from the rearward angle  92  of the generally rhombus-shaped ring  88  of the control apparatus  48 . 
         [0252]    The generally rhombus-shaped ring  88  of the control apparatus  48  has a top angle  94  and a bottom angle  96 . The top angle  94  of the generally rhombus-shaped ring  88  of the control apparatus  48  and the bottom angle  96  of the generally rhombus-shaped ring  88  of the control apparatus  48  when moved cause the generally rhombus-shaped ring  88  of the control apparatus  48  to deform and move the first attaching apparatus  44  and the second attaching apparatus  46  relative to each other, and in doing so, moves the first bone unit  32  and the second bone unit  34  relative to each other. 
         [0253]    The generally rhombus-shaped ring  88  of the control apparatus  48  is made from a non-memory metal so as to allow it to maintain its deformed shape once deformed, and is deformed to move the first attaching apparatus  44  and the second attaching apparatus  46  relative to each other in a range of 1-3 mm.

[0165] STEP  2 : Inserting the at least one second pin  70  transversely at least into the second bone unit  34 , leaving the end  68  of the at least one second pin  70  sticking out from the second bone unit  34  on the one side  80  of at the least one of the bones  36  and the joint  38 . [0166] STEP  3 : Positioning the apparatus  30  on the one side  80  of the at least one of the bones  36  and the joint  38 . [0167] STEP  4 : Sliding the first attaching apparatus  44  over the end  54  of the at least one first pin  56  so as to allow the first attaching apparatus  44  to pivot relative to the at least one first pin  56  when the at least one first pin  56  is one first pin  56 , and sliding the second attaching apparatus  46  over the end  68  of the at least one second pin  70 , respectively, and in doing so, mounting the apparatus  30  to the at least one first pin  56  and to the at least one second pin  70 . [0168] STEP  5 : Crimping the end  54  of the at least one first pin  56  and crimping the end  68  of the at least one second pin  70 , and in so doing, affixing the apparatus  30  to the at least one first pin  56  and to the at least one second pin  70 . [0169] STEP  6 : Deforming the control apparatus  48  to produce at least two conditions. In a first of the conditions, the second bone unit  34  is urged in a first direction relative to the first bone unit  32  for one of the distraction, the compression, the static positioning and/or the control of range or relative rotary motion of the at least one of the bones  36  and/or the joint  38 . In a second of the conditions, the second bone unit  34  is urged in a direction other than the first direction for the other one of the distraction, the compression, the static positioning and/or the control of range or relative rotary motion of the at least one of the bones  36  and the joint  38 . 
         [0257]      FIGS. 5-8  depict an apparatus  100  for bridging between a first bone unit and a second bone unit. The apparatus illustrated in  FIGS. 5-8  may include features similar to those described above. The apparatus may include at least one attachment portion and a control portion. The attachment portion may include a locking mechanism. 
         [0258]      FIG. 5  depicts a plate  110 , wherein the plate  110  includes two attachment portions  140  and  180 . The plate  110  may also be referred to as a body, frame, bracket, or scaffold. The plate  110  may include a first surface  112  that extends between a first end  116  and a second end  118 , and a second surface  114  opposite the first surface  112 . The plate  110  may also include a first side  120  that extends between the first end  116  and the second end  118 , and extends between the first surface  112  and the second surface  114 . The plate  110  may also include a second side  122  opposite the first side  120 . 
         [0259]    The plate  110  may include a medial control portion  130  between the two attachment portions  140 ,  180 . The medial control portion  130  may be substantially diamond shaped or rhombus shaped, wherein the plate  110  may comprise the boundary  132  of the diamond and the middle portion  134  may be hollow. 
         [0260]    The first attachment portion  140  may extend between the first end  116  of the plate  110  and the control portion  130 . The second attachment portion  180  may extend between the control portion  130  and the second end  118  of the body. These positions may be reversed, or only one of the attachment portions  140 ,  180  may be present. 
         [0261]    As seen best in  FIG. 5 , the first attachment portion  140  may be substantially rectangular, and may be shaped to receive an external U-shaped locking member  150 , described below. The first attachment portion  140  may include a first side  142  that is recessed from the first side  120  of the plate  110 , and extends from the first end  116  of the plate  110  to the medial control portion  130 . The first attachment portion  140  may also include a second side  144 , which may be continuous with the second side  122  of the plate  110  and is opposite the first side  142  of the first attachment portion  140 . The first attachment portion may contain a plurality of apertures. In the example shown, the first attachment portion  140  includes a first aperture  146  and a second aperture  148 . The apertures  146 ,  148  may be substantially circular and may be shaped to each receive at least one bone fragment fixation pin. The pin may be selected from the group consisting of a K-wire and a rod. 
         [0262]    In an alternative embodiment, the first side  142  of the first attachment portion  140  may include a dovetail or rail feature, designed to fit into a complementary groove feature on a top interior surface  154  of a central channel  152  in the U-shaped locking member  150 . 
         [0263]    The second attachment portion  180  of the plate  110  may also include a plurality of apertures and may be shaped to receive an internal locking mechanism that includes a rod  190  and a set screw  191 , described below. The apertures may be substantially circular and may be shaped to receive at least one bone fragment fixation pin. The pin may be selected from the group consisting of a K-wire and a rod. As best seen in  FIGS. 5-8 , the second attachment portion  180  includes four apertures  181 ,  182 ,  183 ,  184 . The second attachment portion  180  may also include a tunnel  185  that intersects the second end  118  of the plate  110 . The tunnel  185  may also be referred to as a channel or a bore, and may be shaped to receive a rod  190 . The tunnel  185  may include a threaded portion  186  that intersects the second end  118  of the plate  110 . As seen best in  FIG. 8 , the rod  190  may be operatively assembled with the second attachment portion  180  by sliding the rod into the tunnel  185 . The rod  190  may be advanced in the tunnel  185  and secured in the tunnel  185  by a threaded set screw  191  that fastens to the threaded portion  186  of the tunnel  185 . 
         [0264]    As shown best in  FIGS. 8 and 9 , the U-shaped locking member or clip  150  may be formed separately from the plate  110  and may include the central channel  152 , wherein the central channel  152  may be shaped to receive the first attachment portion  140  of the plate  110 . The central channel  152  may include the top interior surface  154 . The U-shaped clip  150  may include a first ridge  156  and a second ridge  158 . The first ridge  156  may include a first interior surface  160  that intersects the top interior surface  154  of the channel, and a first exterior surface  162  that is opposite the first interior surface  160 . The second ridge  158  may include a second interior surface  166  that intersects the top interior surface  154  of the channel  152 , and a second exterior surface  168  that is opposite the second interior surface  166 . The first ridge  156  may also include a first basal surface  164 , and the second ridge  158  may include a second basal surface  169 . 
         [0265]    In an alternative embodiment, basal surfaces  164 ,  169  of a first ridge  156  and a second ridge  158  may be oriented towards a central channel  152 , such that when the U-shaped clip  150  is advanced over the first attachment portion  140 , the basal surfaces  164 ,  169  can extend beyond the second side  144  of the first attachment portion  140  and clamp inward to further secure the clip  150  to the plate  110 . 
         [0266]    The width of the central channel  152  may be slightly smaller than the width of the first attachment portion  140 , so that the central channel receives the first attachment portion with interference. The U-shaped clip  150  may also include a plurality of cutouts, wherein the cutouts may extend across the central channel  152 . The number of cutouts may be equal to the number of apertures in the first attachment portion  140  of the plate  110 . In the example shown, the U-shaped clip  150  contains two substantially semi-circular cutouts  170 ,  172 . The cutouts  170 ,  172  may extend from the first and second basal surfaces  164 ,  169  of the first and second ridges  156 ,  158 . The circumference of the cutouts  170 ,  172  may be slightly smaller than the circumference of the apertures. The cutouts may include circumferential edges that may be beveled or sharpened  174 . 
         [0267]    As seen best in  FIG. 10 , the rod  190  may include an elongated shaft  192  portion  192 , and a head portion  194 . The head portion  194  may be integral to the shaft  192  and the shaft  192  may be located eccentrically or asymmetrically on the head  194 . The elongated shaft  192  may include a plurality of cutouts  195 ,  196 ,  197 ,  198 . The cutouts  195 ,  196 ,  197 ,  198  may comprise a rounded surface portion  199  and a flat bottom portion  193 . 
         [0268]      FIGS. 6-7  illustrate the plate  110  described in  FIG. 5  operatively assembled with a first U-shaped clip locking mechanism  150  and a second rod locking mechanism  190 . Each of the locking mechanisms may be received on a portion of the plate  110 . In the example shown in  FIGS. 6 and 7 , the first locking mechanism  150  is received by the first attachment portion  140  and the second locking mechanism  190  is received by the second attachment portion  180 . The first and second locking mechanisms  150 ,  190  may also be referred to as first and second locking members, locking apparatuses or locking features. The first locking member  150  may be operatively assembled with the first attachment portion  140  by sliding the clip over the first side  142  of the first attachment portion  140 , as seen best in FIGS  6  and  8 . 
         [0269]    In operation, the first attachment portion  140  may be placed against a first bone segment. A K-wire may be placed into at least one of the apertures and further into the bone segment. Additional K-wires may be placed through apertures as needed. The U-shaped clip locking member  150  may be placed onto the first side  142  of the first attachment portion  140  such that the cutouts  170 ,  172  align with the apertures  146 ,  148  in the first attachment portion  140 . The U-shaped clip  150  may then be advanced toward the second side  144  of the first attachment portion  140  such that the first ridge  156  and the second ridge  158  deflect outwards from the central channel to receive the first attachment portion  140  of the plate  110 . For example, the clip  150  may slide in a direction that is oblique, transverse, or perpendicular to the apertures  146 ,  148 . When the U-shaped clip  150  is advanced to fully receive the first attachment portion  140 , the cutouts  170 ,  172  may at least partially overlap the apertures  146 ,  148  and the sharpened edges  174  of the cutouts  170 ,  172  may cut a groove into the surfaces of the K-wires. This may provide an interference fit with the K-wires, and thus may secure the K-wires to the plate  110 . 
         [0270]    In operation, the second attachment portion  180  may be placed against a second bone segment. The rod  190  may be placed into the tunnel  185 , such that the rod  190  is positioned closer to the second side  122  of the plate  110 , and such that the rounded surfaces  199  of the cutouts  195 ,  196 ,  197 ,  198  are disposed towards the first side  120  of the plate  110 . A K-wire may be extended through each of the apertures  181 ,  182 ,  183 ,  184 , and further into the second bone segment. After the pins have been placed through the apertures  181 ,  182 ,  183 ,  184  and into the bone segment, the set screw  191  may be actuated such that as it turns, it may act on the head  194  of the rod  190  to advance the rod  190  in the tunnel  185  toward the first end  116  of the plate  110 . As the rod  190  is advanced in the tunnel  185 , the cutouts  195 ,  196 ,  197 ,  198  at least partially overlap the apertures  181 ,  182 ,  183 ,  184 , and contact the pins, such that the pins become fixed against the side of the apertures and thus become secured to the plate  110 . 
         [0271]    In an alternative embodiment, the set screw  191  may be integral to the rod  190 . In this example, the rod and set screw may be coaxial. Actuation of the threaded screw portion turns the rod and simultaneously drives it along tunnel  185  to wedge pins to the plate. The clamping action may be due to rotation of the cutouts  195 ,  196 ,  197 ,  198  against the pins, axial advancement of the cutouts  195 ,  196 ,  197 ,  198  against the pins, or both. 
         [0272]    The medial control portion  130  may include a generally diamond-shaped or rhombus-shaped ring, which may be deformable as described above. The diamond-shaped ring  130  may include four interior angles  135 ,  136 ,  137 ,  138 , which may be defined by the boundary  132  of the diamond  130 . Angle  135  may be located nearest the first side  120  of the plate  110 . Angle  136  may be located nearest the second side  122  of the plate  110 . Angle  137  may be located nearest the first end  116  of the plate  110  and angle  138  may be located nearest the second end  118  of the plate  110 . 
         [0273]    In operation, the medial control portion  130  may be compressed such that angles  137  and  138  become more obtuse and such that the distance between the first end  116  of the plate  110  and the second end  118  of the plate  110  becomes less. Alternatively, the medical control portion  130  may be stretched such that angles  135  and  136  become more obtuse, and the distance between the first end  116  of the plate  110  and the second end  118  of the plate  110  increase.
