Method and apparatus for orthopedic implant
A tibial implant may include a plurality of implant subunits. The implant subunits may be configured for individual insertion within a wedge-shaped-void of the tibia. The implant subunits may further be configured for assembly in order to provide an implant substantially covering an exposed portion of cortical bone formed when performing a surgical osteotomy. Methods and kits for insertion and assembly of implants are further described.
1. A kit for performing a surgical tibia repair, the kit comprising:
a plurality of implant subunits;
wherein said plurality of implant subunits are configured for arrangement with respect to one another to form an implant shaped to substantially cover an exposed rim of cortical bone adjacent a wedge-shaped void in a patient's tibia;
one or more linking members; and
instructions for how to connect said plurality of implant subunits to said one or more linking members and how to automatically position said implant subunits to form said implant when tightening said one or more linking members;
wherein said plurality of implant subunits include a plurality of implant subunits configured for bearing a patient's weight, said plurality of implant subunits comprising a substantially hollow carbon-cage.
2. The kit of claim 1 wherein said plurality of implant subunits include one or more secondary implant subunits.
3. The kit of claim 2 wherein said one or more secondary implant subunits are configured for positioning over an exposed region of trabecular bone adjacent the wedge-shaped void.
4. The kit of claim 2 wherein said one or more secondary implant subunits are sized and shaped for positioning over an exposed region of trabecular bone adjacent said wedge-shaped void;
wherein said one or more secondary implant subunits assist in positioning a generally U-shaped portion of said plurality of implant subunits over said exposed rim of cortical bone when tightening said one or more linking members.
5. The kit of claim 2 wherein said one or more secondary implant subunits are sized and angled for positioning over an exposed region of trabecular bone adjacent said wedge-shaped void;
wherein at least one of said one or more secondary implant subunits includes at least one surface that is complementary in shape to at least one other surface included in at least one of said plurality of implant subunits.
