Patent ID: 8888785

Claim:
A method for performing an open wedge osteotomy, the method comprising the steps of: cutting a bone with a cutting apparatus along a cutting plane, with the cut terminating at a boundary line to provide a wedge-like opening having a proximal end, the cutting apparatus comprising a targeting apparatus for identifying the cutting plane through the bone and said boundary line for terminating the cut made along the cutting plane, and a keyhole drill guide comprising a proximal hole and a distal hole, each of the proximal hole and the distal hole intersecting the cutting plane; forming a distal keyhole and a proximal keyhole in a bone surface adjacent to the wedge-like opening, the distal keyhole and the proximal keyhole being formed to overlap at least a portion of the proximal end of the wedge-like opening in the bone; and positioning a keyed wedge-shaped implant in the wedge-like opening and in the distal and proximal keyholes.
