Abstract

The femoral head prosthesis has a straight fixing stem for implantation in a femur which is provided with a longitudinal bore which extends along the axis of the stem. The stem can be slid along a centering rod previously positioned within a surgically prepared bone cavity of the femur to guide the stem into a bone cement bed. The centering rod is initially put in place with a cavity barrier followed by placement of the bone cement bed. After initial curing of the bone cement, the rod can be disengaged from the cavity barrier and removed from the stem.
