Claim 0:
1. A system for minimizing bone loss during the removal of a femoral implant, the femoral implant including lateral and medial sides, a stem, an upper textured portion, and a neck, bone growth affixing the upper textured portion to the femur, the system comprising:
a lateral tool including proximal and distal ends and an outer wall with an arcuate extent, the lateral tool further including opposing side walls defining an arcuate interior, each side wall including a first angled extent and a second curved extent, the curved extent being sharpened, a window formed within each of the opposi.ng side walls, a threaded aperture formed within the proximal end, the distal end including a curved and sharpened leading edge, the lateral tool adapted to be inserted between the femur and the lateral side of the femoral implant to thereby separate the textured portion from the femur:
a first impact tool threadably secured to the threaded aperture of the lateral tool, the first impact tool allowing the leading edge and curved extents of the lateral tool to cut bone growth between the femoral implant and the femur;
a medial tool including proximal and distal ends, the medial tool including opposing side walls, with each side wall including inner and outer edges, the outer edges being sharpened, a U-shaped trough with a sharpened leading edge positioned at the distal end of the medial tool, an opening formed through the medial tool, the medial tool adapted to be inserted between the femur and the medial side of the femoral implant with the neck of the implant extending through the opening;
a second impact tool threadably secured to the threaded aperture of the medial tool, the second impact tool allowing the leading edge and the outer edges of the medial tool to cut bone growth between the femoral implant and the femur;
wherein when both the lateral and medial tools inserted into the femur, the curved extents of the lateral tool overlap the outer edges of the medial tool.
