Patent ID: 8795381

Claim:
A method for hip arthroplasty, comprising: fixing a prosthetic femoral head in a position adapted to be rotatable with respect to a patient's acetabulum; creating a bore in a patient's femur from a side of the patient's femur opposite the patient's acetabulum and extending in a direction toward the patient's acetabulum; joining an end of a prosthetic femoral neck to the prosthetic femoral head after advancing the end of the prosthetic femoral neck into the bore to engage the prosthetic femoral head; positioning an intramedullary rod in the patient's femur; and fixing the position of the prosthetic femoral neck with respect to the patient's femur by joining the prosthetic femoral neck to the intramedullary rod; wherein the fixing the position of the prosthetic femoral neck with respect to the femur comprises rotationally engaging the intramedullary rod to the prosthetic femoral neck; wherein the intramedullary rod includes a threaded neck fixation bore extending from a top side of the intramedullary rod toward a bottom side of the intramedullary rod aligned within the threaded bore; wherein the intramedullary rod further includes a tapered neck fixation bore extending from a proximal side of the intramedullary rod to a distal side of the intramedullary rod aligned within the tapered bore, and wherein the threaded bore and the tapered bore fix the prosthetic femoral neck relative to the intramedullary rod.
