Method and apparatus for performing a minimally invasive total hip arthroplasty

Image Number 15 for United States Patent #6991656.

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 and 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. In one exemplary embodiment, 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. In this embodiment, 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. In an alternative embodiment, preparation of the femur is effected through the anterior incision, with the operative hip placed in hyperextension.
