ABSTRACT:
Instrumentation for preparing a femur for implantation of a prothesis therein, the femur including a femoral shaft having a femoral canal therein defined by sidewalls, the prosthesis being constructed and arranged to be received within the femoral canal, the instrumentation including: at least one initial compactor instrument having a proximal portion and a distal broach portion, the broach portion being adapted to conform substantially to a proximal end of the femoral canal so as to compact bone in the sidewalls thereof without intentionally removing bone from the femoral canal; a second type of compactor instrument having a proximal portion and a distal broach portion, the secondary compactor instrument portion being constructed and arranged to conform substantially to the shape of the prosthesis so as to further compact bone in the sidewalls of the proximal end of the femoral canal such that the compacted sidewalls conform substantially to the shape of the prosthesis; and a final type of compactor instrument having a proximal portion and an elongated distal broach portion, the elongated broach portion being adapted to extend into the femoral canal and compact bone in sidewalls of the femoral canal at a location distal to previously compacted sidewalls of the proximal end of the femoral canal.
