ABSTRACT:
A femoral prosthesis has load shoulders for transferring normal loading to the femur at the proximal end to reduce stress shielding. The femur is resected to provide a flat load shoulder perpendicular to the axis of the femur. The prosthesis has a mating load shoulder in its proximal section which lands on the load shoulders formed in the femur. The prosthesis has a stem that extends downward to a distal end. The intermediate portion of the stem between the distal end and the proximal end is reduced in diameter to add flexibility. The distal end is substantially the diameter of the bone cavity.
