Abstract
An apparatus and method for performing an open wedge osteotomy. The apparatus includes devices for forming an open wedge osteotomy in bone, including a keyed-wedge implant. The method includes the steps of forming a cut in a bone, forming a keyhole in the bone surface at the proximal end of the cut, and positioning a keyed wedge-shaped implant into the cut formed into the bone.
Claims7
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.
