Abstract:
1. A method for performing a high tibial, dome osteotomy so as to adjust the lateral and/or angular disposition of the tibial plateau relative to the lower portion of the tibia, the method comprising: forming an arcuate osteotomy cut in the tibia so as to subdivide the tibia into an upper portion and a lower portion; manipulating the upper portion and the lower portion so as to adjust the lateral and/or angular dispositions of the upper portion and the lower portion relative to one another; forming a pair of keyholes in the tibia along the arcuate osteotomy cut; forming a keyhole slot in the tibia so as to connect the two keyholes; forming a fixation hole in the tibia for each keyhole; providing an implant comprising a pair of keys connected by a bridge, each key comprising a bore for receiving a fixation screw therein; inserting the implant into the tibia so that the keys are disposed in the keyholes, and so that the bores of the keys are aligned with the fixation holes of the keyholes; and inserting fixation screws through the bores of the keys and into the fixation holes of the keyholes so as to stabilize the upper portion of the tibia and the lower portion of the tibia relative to one another while healing occurs.
