Full Description:
FIELD OF THE INVENTION 
       [0001]    The invention generally relates to an orthopedic construct comprising an orthopedic plate that provides for improved compression in associated bone, in particular, to achieve fusion. The plate can, in the alternative, include one or more compression screws, one or more staples, or both. The construct is capable of inducing compression into the associated bone, and in an alternative embodiment, the plate has a translating portion which is associated with at least either a screw (i.e., compression screw) or one leg of a bone staple. 
       BACKGROUND OF THE INVENTION 
       [0002]    Orthopedic plating has been practiced for some time to repair osteotomy sites, bone fractures, and other sites where bones need to be held in close proximity to facilitate bone healing, in particular bone fusion. Typically a bone plate is affixed by means of screws to two or more bone portions so as to immobilize the portions relative to each other and thereby facilitate formation of a bone bridge or callus between the two portions. In some cases a bone plate and screws are oriented and tightened to provide a fixed amount of initial compressive force between the bone portions by drawing the bone portions towards each other. In some cases, a bone screw will couple with a compression slot in a bone plate and provide initial compressive force between the bone portions by drawing the portions towards each other by a fixed distance. Generally speaking, with these approaches, the amount of compression between the bone portions diminishes over time due to one or more of loosening of the screws and plates, remodeling of the bones, applied mechanical forces, or other reasons. Since bone is a living organism, it reacts to the load applied in ways that are different than non-living materials, such as metal, plasterboard or wood. It is known that the amount of compression applied to the bone by fasteners can change or reduce over time, due to necrosis or erosion of bone. 
         [0003]    Another limitation of using plates for fixation of bone portions is that while the portions in contact with the plate may be immobilized relative to each other the portions of the bone furthest away from the plate may not be sufficiently immobilized relative to each other due to flexing of the plate, or bone, or both. This is a particular problem in load bearing situations. For example, a plate applied to the dorsal surface of a metatarsal may immobilize the bone portions adjacent to the plate yet the bone portions on the plantar side of the metatarsal may suffer significant movement relative to each other during application of force to the metatarsal by, for example, standing on the foot. 
         [0004]    In another approach, staples can be used to provide a fixed amount of initial compressive force between two or more bone portions by drawing the portions towards each other at the crown of the staple. In some staples the legs of the staples may be angled such that the ends of the legs are closer to each other than the separation of the legs at the crown. Such staples may be initially placed in an elastically deformed state and thereby also apply a compressive force that continues over time at the ends of the staple legs, for a much longer time than the initial compressive force described above for plates, particularly if the staple is comprised of a superelastic alloy, for example, Nitinol. The force so applied is below the surface of the bone portions. However, a disadvantage of using staples for fixation of bone portions is that the crown of the staple is far less resistant to bending than a plate. In load bearing applications the use of staples is insufficient to immobilize the bone portions over time. 
         [0005]    It is desirable to have an orthopedic plating construct that can immobilize bone portions in load bearing applications where the portions are initially compressed into close proximity with each other, the construct prevents motion between the portions due to applied loads, and the construct applies compressive force to immobilize the portions over the healing time. 
         [0006]    It is desirable to have an orthopedic plating construct that can achieve joint compression on the side of the bone farthest away from the plating surface (i.e., plantar compression with dorsal plating). 
         [0007]    It is desirable to have an orthopedic plating construct that can improve upon the strength and stiffness of staple-only constructs and improves compression in the presence of plate-only constructs.

     DETAILED DESCRIPTION OF THE INVENTION 
     Embodiment 1—Full Thickness Slot 
       [0069]      FIG. 1  illustrates active compression plate system  1  in an unassembled configuration, comprised of bone plate  10 , bone staple  30 , and one or more fasteners  40  in accordance with a first embodiment of the invention. In one example of use plate  10  is placed against a patient&#39;s bone, one fastener  40  is inserted through fastener hole  12  of plate  10  and affixed to the bone, one staple  30  is inserted through plate slot  16  and into the patents bone, and a second fastener  40  is inserted through fastener hole  12  in plate  10  and affixed to the bone. It should be noted that the term “slot”, refers to herein specifically as a full thickness recess or full thickness opening which extends from a first proximal plate surface to a second distal plate surface. With reference to  FIGS. 1 to 8 , active compression plate system  1  will be further described below. 
         [0070]    Bone plate  10  may have a profile looking down from the top of a modified rectangle, with equivalent opposing parallel long sides  21  defining straight lateral edges  22 , and with rounded short ends  23  having circular lateral edges  24 . Bone plate  10  is comprised of a proximal surface  13  and a distal surface  14  having a first thickness  15  therebetween, at least one slotted portion  16 , one or more through holes  17  and one or more fastener holes  12 . As illustrated in  FIGS. 1-8 , slotted portion or slot extends all the way through the plate, from a first surface to a second surface of the plate. Slotted portion  16 , through holes  17  and fastener holes  12  may be generally aligned along plate longitudinal axis LA. In one embodiment plate is comprised of one slot, two through holes and two fastener holes. Fastener holes  12  may be smooth walled, threaded, for example for use with threaded fasteners, or formed as compression slots having an angled shoulder that cooperates with a screw to apply a transverse motion to the plate as the screw is tightened against a bone. Optionally bone plate  10  may be comprised of one, two, three, four, five, six, or more fastener holes (not shown) for use with various fasteners as is known in the art. 
         [0071]    In use slot  16  accommodates one or more staple crowns as will be described below. Slot may extend over the full thickness of plate as shown in  FIGS. 1 and 7  and have the characteristics of an opened bottom slot. Slot terminates at through openings  17  that accommodate the legs of the staple when it is assembled with the plate. Slot  16  is intermediate or disposed between the screw holes  12 . Slot is sized to accommodate staple bridge. It should be understood that the term staple “bridge” as used herein defines the portion of the staple that connects or is disposed between the two staple legs. Slot dimensions are larger than staple bridge dimensions such that bridge can pass through slot in a sliding fit or a less snug fit. In an alternative embodiment slot is sized to interact with staple bridge as an interference fit. 
         [0072]    It should be noted that in certain embodiments described herein, the slot or slotted portion, extending the full thickness of the plate may be interchanged with a recess or recessed portion, having a partial thickness of the plate. 
         [0073]    Bone plate  10  can be curved along longitudinal axis LA or normal to axis LA, or both. In one embodiment plate  10  is curved or contoured to mimic the typical shape of bone surfaces at the intended implantation location. In another embodiment plate  10  is curved or contoured to mimic the shape of the specific bone surface onto which the plate will be affixed. 
         [0074]    Bone plate  10  may comprise of titanium, stainless steel, Nitinol, or other metals; Poly Ether Ether Ketone (PEEK) or other polymers; alumina or other ceramics, bioabsorbable materials including metal, ceramic, or polymer, in whole or in part, or combinations thereof, or other materials. 
         [0075]    Bone staple  30  is comprised of two or more legs  31  joined by bridge  32 . An included angle α between leg  31  and bridge  32  (see  FIG. 2 ) falls between 45° and 135°. During insertion of staple  30  into the patient&#39;s bone angle α is held at 90°+/−10°, and preferably +/−5°, and more preferably +/−3°) in order to facilitate insertion of the staple into the bone, and once implanted tends to return to a pre-programmed second configuration as shown in  FIG. 3  in which the legs angle inward toward each other by 5-20° from the insertion position. Legs and bridge may be generally straight (as illustrated) or curved. Staple  30  may be comprised of barbs or other gripping structure  33 , which, in certain embodiments, may be disposed only on the staple legs to facilitate secure locking of staple  30  to a patient&#39;s bone. 
         [0076]    Bone staple  30  may be comprised of a wire like structure that has been formed into a shape similar to that of the English language letter U. Bone staple  30  may comprise of titanium, stainless steel, Nitinol, or other metals; polyetheretherketone (PEEK) or other polymers; alumina or other ceramics, bioabsorbable materials including metal, ceramic, or polymer, in whole or in part, or other materials. Superelastic Nitinol is a preferred material of construction for staples used in the active compression plate system  1  due to the large amount of elastic strain (up to 9%) that superelastic nitinol can reversibly sustain. 
         [0077]    Fastener  40  may be comprised of a non-locking bone screw, a locking bone screw, a compression bone screw, a peg, or other fasteners. In general, bone screws are preferred. When more than one fastener is used in active compression plate system  1  the fasteners used can be any combination of non-locking bone screws, locking bone screws, compression bone screws, pegs, or other fasteners. 
         [0078]    Fastener  40  may be comprised of titanium, stainless steel, Nitinol, or other metals; Poly Ether Ether Ketone (PEEK) or other polymers; alumina or other ceramics, bioabsorbable materials including metal, ceramic, or polymer, in whole or in part, or other materials. 
         [0079]    In an exemplar method of use of active compression plate system  1 , a patient is prepared for surgery and surgical access to one or more bones is achieved. Access may be accomplished by open surgery, small incision surgery, or percutaneously. 
         [0080]    The surgical procedure chosen, planned, or performed will be for repair of bone fracture, repair of osteotomy, bone fusion, or other procedures in which two or more bones or bone portions must be held in close proximity to each other to facilitate bone healing, and in particular to facilitate bone fusion. 
         [0081]    The patient&#39;s bone or bone portions are exposed and reduced to the desired positions. 
         [0082]    Bone staple  30  is placed into the bone or bone portions and the staple is allowed to hold the bone or bone portions at the desired positions relative to each other. 
         [0083]    Slot  16  of plate  10  is passed over bridge of staple  30  and plate  10  is brought into contact with the patient&#39;s bone. 
         [0084]    Optionally a drill guide is inserted into at least one fastener hole  12  and a hole is drilled into the patient&#39;s bone. 
         [0085]    Plate  10  is affixed to at least one bone or bone portion by means of inserting at least one fastener  40  such as a bone screw into fastener hole  12  and into the drilled hole (if any) then advancing the fastener into the patient&#39;s bone. In a preferred embodiment plate  10  is affixed to at least two bones or bone portions by means of at least two bone screws.

       Embodiment 4—Translating Screw Hole 
       [0134]      FIGS. 28 to 32  illustrate active compression plate system fourth embodiment  200 , comprised of translating bone plate  210 , bone staple  30  (not shown), fasteners  40  (not shown), recessed portion  260 , and fastener holes  12 . Bone staple  30 , fasteners  40 , and fastener holes  12  have the same structure and are made of the same materials as bone staples  30 ,  30 ′,  30 ″, fasteners  40 ,  40 ′,  40 ″, and fastener holes  12 ,  12 ′,  12 ″ of active compression plate systems  1 ,  1 ′,  1 ″, discussed above, except as noted below. Slotted portion  260  is comprised of through holes  270  and has the same structure and is made of the same materials as recessed/slotted portions  16 ,  16 ′,  16 ″ and through holes  17 ,  17 ″,  17   a ,  17   b  of active compression plate systems  1 ,  1 ′,  1 ″, discussed above, except as noted below. It is understood that plate  210  can be comprised of full thickness slot or partial thickness recess  260  and that the two may be interchangeable depending on the bone quality, patient anatomy or surgeon preference. 
         [0135]    Translating bone plate  210  has longitudinal axis LA and is further comprised of locking portion  280  and translating portion  290 . Locking portion  280  and translating portion  290  have the same structure and are made of the same materials as bone plates  10 ,  10 ′,  10 ″ of active compression plate systems  1 ,  1 ′,  1 ″, discussed above, except as noted below. It is understood that locking portion  280  may be comprised of an angled or bent portion in the intermediate portion, similar to bone plate  10 ″. 
         [0136]    Locking portion  280  is comprised of elongated plate through-hole  282  having plate hole counterbore  284  formed into and below the proximal surface of plate portion  280 , and one or more plate hole pocket  286  formed into the inner wall  288  of plate portion  280 . Translating portion  290  is comprised of retaining flange  292  formed adjacent to proximal surface of plate portion  290  and one or more snap tabs  296  each having barb  298  at the tab distal end and a clearance relief  299  on the side of the tab opposite the barb. 
         [0137]    Locking portion  280  and translating portion  290  are assembled by inserting distal end of translating portion into locking portion plate hole counterbore  284  then into plate through hole  282  so as to reversibly deflect snap tab(s) into clearance relief(s)  299  of plate translating portion. Further insertion causes plate translating portion retaining flange  292  to enter locking portion plate hole counterbore  284  and causes snap tab(s) to deflect outward and into plate hole pocket  286  of plate locking portion. Translating portion  290  is thereby prevented from exiting locking portion  280  by means of retaining flange  292  cooperating with counterbore  284  in combination with barb(s)  298  cooperating with pocket(s)  286 . However translating portion  290  is allowed to translate along longitudinal axis LA of locking portion due to designed clearances along longitudinal axis LA between the lengths of plate hole  282 , counterbore  284  and flange  292  and between the lengths of barb(s)  298  and pockets  286 . 
         [0138]    In an exemplary method of use of active compression plate system  200 , a patient is prepared for surgery and surgical access to one or more bones is achieved. Access may be accomplished by open surgery, small incision surgery, or percutaneously. 
         [0139]    The surgical procedure chosen, planned, or performed will be for repair of bone fracture, repair of osteotomy, bone fusion, or other procedures in which two or more bones or bone portions must be held in close proximity to each other to facilitate bone healing, and in particular to facilitate bone fusion. 
         [0140]    The patient&#39;s bone or bone portions are exposed and reduced to the desired positions. 
         [0141]    Plate  200  is positioned such that recess  260  straddles a gap between two adjacent bones or bone portions. 
         [0142]    Optionally a drill guide is inserted into at least one fastener hole  12  of translating portion  290  and a hole is drilled into the patient&#39;s bone 
         [0143]    Translating portion  290  is loosely affixed to at least one bone or bone portion by means of inserting at least one fastener  40  such as a bone screw into the fastener hole  12  of translating portion  290  and into the drilled hole (if any) then advancing the fastener into the patient&#39;s bone. 
         [0144]    Any gap between the bone or bone portions immediately underlying plate  200  is reduced and a second fastener  40  such as a bone screw is inserted into hole  12  of locking portion  280 , into a drilled hole (if any) and then advanced into the patient&#39;s bone causing the bone portions or bones to be locked together in a reduced configuration. 
         [0145]    The bone or bone portions are further advanced towards each other to reduce any gap therebetween. This is allowed by system  200  due to the allowable longitudinal motion between translating portion and fixed portion. Fastener  40  on translating portion is immediately advanced to lock translating portion and adjacent locking portion of plate to the bone or bone portions. 
         [0146]    Bone staple  30  is placed through recess  260  and through hole(s)  270 , then into the bone or bone portions and the staple is allowed to hold the bone or bone portions at the desired positions relative to each other. The staple ends apply active compression forces against the bone at a distance below the bone plate distal surface. 
         [0147]    In an alternate method staple  30  can be placed into the bone followed by placement of bone plate  210  and use of the translating aspect of system  200 .

Bone staple  30 , fasteners  40 , and fastener holes  12  have the same structure and are made of the same materials as bone staples  30 ,  30 ′,  30 ″, fasteners  40 ,  40 ′,  40 ″, and fastener holes  12 ,  12 ′,  12 ″ of active compression plate systems  1 ,  1 ′,  1 ″, discussed above, except as noted below. Slotted portion  360  is comprised of through-holes  370  and has the same structure and are made of the same materials as recessed/slotted portions  16 ,  16 ′,  16 ″ and through holes  17 ,  17 ″,  17   a ,  17   b  of active compression plate systems  1 ,  1 ′,  1 ″, discussed above, except as noted below. It is understood that plate  310  can be comprised of full thickness slot ( 360 ) or partial thickness recess  360  (not shown). 
         [0149]    Translating bone plate  310  has longitudinal axis LA and is further comprised of locking portion  380  and translating portion  390 . Locking portion  380  and translating portion  390  have the same structure and are made of the same materials as bone plates  10 ,  10 ′,  10 ″ of active compression plate systems  1 ,  1 ′,  1 ″, discussed above, except as noted below. It is understood that locking portion  380  may be comprised of an angled or bent portion in the intermediate portion, similar to bone plate  10 ″, as illustrated in the figures.

         [0151]    Locking portion  380  and translating portion  390  are assembled by inserting elongated tab  391  of translating portion into elongated slot  381  of locking portion so as to reversibly deflect snap tab(s) into clearance relief(s)  399  of plate translating portion. Further insertion causes plate translating portion retaining flange  392  to contact locking portion plate proximal surface and causes snap tab(s) to deflect outward and into plate hole pocket  386  of plate locking portion. Translating portion  390  is thereby prevented from exiting locking portion  380  by means of retaining flange  392  cooperating with plate  380  proximal surface in combination with barb(s)  398  cooperating with pocket(s)  386 . However translating portion  390  is allowed to translate along longitudinal axis LA of locking portion due to designed clearances along longitudinal axis LA between the lengths of plate tabs  381 ,  391  and plate slots  383 ,  393  and between the lengths of barb(s)  398  and pockets  386 . 
         [0152]    In an exemplary method of use of active compression plate system  300 , a patient is prepared for surgery and surgical access to one or more bones is achieved. Access may be accomplished by open surgery, small incision surgery, or percutaneously. 
         [0153]    The surgical procedure chosen, planned, or performed will be for repair of bone fracture, repair of osteotomy, bone fusion, or other procedures in which two or more bones or bone portions must be held in close proximity to each other to facilitate bone healing, and in particular to facilitate bone fusion. 
         [0154]    The patient&#39;s bone or bone portions are exposed and reduced to the desired positions. 
         [0155]    Plate  300  is positioned such that recess  360  straddles a gap between two adjacent bones or bone portions. 
         [0156]    Optionally a drill guide is inserted into fastener hole  12  of translating portion  390  and a hole is drilled into the patient&#39;s bone 
         [0157]    Translating portion  390  is loosely affixed to at least one bone or bone portion by means of inserting at least one fastener  40  such as a bone screw into the fastener hole  12  of translating portion  390  and into the drilled hole (if any) then advancing the fastener into the patient&#39;s bone. 
         [0158]    Any gap between the bone or bone portions immediately underlying plate  300  is reduced and a second fastener  40  such as a bone screw is inserted into hole  12  of locking portion  380 , into a drilled hole (if any) and then advanced into the patient&#39;s bone causing the bone portions or bones to be locked together in a reduced configuration. 
         [0159]    The bone or bone portions are further advanced towards each other to reduce any gap therebetween. This is allowed by system  300  due to the allowable longitudinal motion between translating portion and fixed portion. Fastener  40  on translating portion is immediately advanced to lock translating portion and adjacent locking portion of plate to the bone or bone portions. 
         [0160]    Bone staple  30  is placed through recess  360  and through hole(s)  370 , then into the bone or bone portions and the staple is allowed to hold the bone or bone portions at the desired positions relative to each other. The staple ends apply active compression forces against the bone at a distance below the bone plate distal surface. 
         [0161]    In an alternate method staple  30  can be placed into the bone followed by placement of bone plate  310  and use of the translating aspect of system  300 . 
         [0162]    In another method of surgery, active compression is achieved by first, exposing the bone surface. Next, an orthopedic plate  310  having a translation portion  390  having a translation portion fastener hole and a locking portion having a locking portion fastener hole is placed on the bone, and fastened to the bone with a first fastener and a second fastener, and optionally a third fastener. It should be noted, that either the second or the third fastener is a compression fastener and the first fastener is a locking fastener. Then, the first fastener is locked in the locking portion fastener hole to form a locked relationship and a second fastener is placed in the translation portion fastener hole and the compression fastener drives active compression in the translation portion  360 .
