ABSTRACT:
A joint prosthesis, especially for a hip joint has a metal shaft receivable in the marrow cavity of the bone, a closure plate at the upper end of the shaft, and a formation adapted to form the ball joint. The underside of the plate and the shaft along its length are provided with a layer of synthetic bone material which is of greater thickness in the region of the plate and adjoining the plate, corresponding to the greater stress region of the bone, than along the shank remote from the plate.
