Claim:
1. A system for performing modular hip resurfacing, comprising: an alignment guide configured for sizing of a femoral head and for insertion of a guide pin into the femoral head and a femoral neck; a modular cannulated cylindrical reamer assembly configured for cylindrical reaming of the femoral head, distal osteotomy of the femoral head above an articular rim of the femoral head, and drilling of a central bone channel into the femoral head and femoral neck; a saw guide configured for guiding a proximal osteotomy of the femoral head, the proximal osteotomy spaced apart from the distal osteotomy and located proximal to the articular rim; a soft tissue protector configured for protection and retraction of soft tissues; a hip retractor configured for retracting a hip joint following the cylindrical reaming; an outer hole drill guide configured for drilling outer holes adjacent to the central bone channel; and a modular hip resurfacing implant, the modular hip resurfacing implant including a cap portion and a central stem, wherein an underside of the cap portion includes at least one implant threaded hole located between the central stem and a central rim of the cap portion, the at least one implant threaded hole configured for use with modular threaded attachments that are extendable into the femoral head, the femoral neck, and a lateral femoral shaft cortex of a proximal femur, wherein the central stem extends away from the cap portion from a first end to a second end opposite the first end, wherein the second end has threading configured to accommodate threaded attachments; wherein the modular cannulated cylindrical reamer assembly includes:
