Abstract: An improved hybrid femoral component design for a hip prosthesis has a cross section having a rectangular or other shape lateral end and a circular or elliptical medial end, where the medial anterior-posterior (AP) dimension of the implant is greater than the lateral AP dimension of the implant. The cross sectional axis of the circular or elliptical medial end may be inclined or partially offset in relation to the axis of the rectangular lateral end. The lateral side of the proximal stem may have a plurality of shapes. This hybrid proximal stem design lends itself to a hybrid proximal femoral preparation surgical technique where the medial calcar may be power reamed and the lateral femur and canal may be broached.
