  • Patent number: 7833275
    Abstract: A method and apparatus for performing a minimally invasive total hip arthroplasty. An approximately 3.75-5 centimeter (1.5-2 inch) anterior incision is made in line with the femoral neck. The femoral neck is severed from the femoral shaft and removed through the anterior incision. The acetabulum is prepared for receiving an acetabular cup through the anterior incision, and the acetabular cup is placed into the acetabulum through the anterior incision. A posterior incision of approximately 2-3 centimeters (0.8-1.2 inches) is generally aligned with the axis of the femoral shaft and provides access to the femoral shaft. Preparation of the femoral shaft including the reaming and rasping thereof is performed through the posterior incision, and the femoral stem is inserted through the posterior incision for implantation in the femur.

  • Patent number: 6953480
    Abstract: A method and apparatus for performing a minimally invasive total hip arthroplasty. An approximately 3.75-5 centimeter (1.5-2 inch) anterior incision is made in line with the femoral neck. The femoral neck is severed from the femoral shaft and removed through the anterior incision. The acetabulum is prepared for receiving an acetabular cup through the antenor incision, and the acetabular cup is placed into the acetabulum through the anterior incision. A posterior incision of approximately 2-3 centimeters (0.8-1.2 inches) is generally aligned with the axis of the femoral shaft and provides access to the femoral shaft. Preparation of the femoral shaft including the reaming and rasping thereof is performed through the posterior incision, and the femoral stem is inserted through the posterior incision for implantation in the femur.

  • Patent number: 6860903
    Abstract: A method and apparatus for performing a minimally invasive (i. e., with the wound developed under an incision being substantially the same size as the incision throughout the depth of the wound) total hip arthroplasty. The apparatus includes a provisional femoral head allowing for radial placement thereof on a provisional femoral neck as well as a posterior retractor sleeve for allowing access to a femur through a posterior incision.
