Abstract
This invention relates to a femoral insert for a hip joint prothesis for use in a femur that has been cut across the femoral neck to form a cut surface. The insert includes a stem having a proximal end attachable to a generally spherical head member, a distal end and a bend located therebetween. A collar is provided for transferring axial loads from the stem to the femur at the cut surface. A sleeve is secured within the femur, the sleeve having a central orifice for receiving the stem. The sleeve permits the stem to move axially but restricts the stem from any rotational or toggling movement. The sleeve is secured into the femur below the cut surface.
