Abstract
The femoral component for a hip joint prosthesis has an intramedullary stem having a free distal region, a proximal region extending to a neck for receiving a ball head, a medial side and a lateral side. The stem has screw holes extending from said lateral side to said medial side for receiving bone screws in the lateral to medial direction for fixation of said stem to the medial cortex. The stem is coupled primarily to the medial cortex of the femur and only secondarily to the cancellous portion of the proximal femur to aid the rotational (torsional) stability of the implant.
