摘要： Articular prosthetic device which comprises: a half-shell having an inner surface and an insert having an outer surface, the inner surface of the half-shell and the outer surface of the insert being shaped so that the insert is retained within the half-shell when it is pushed therein, by applying a force thereto directed along an axis of impaction, with surface contact between the two mating surfaces, the outer surface of the insert comprising a plurality of sections, each section forming, in cross-section, with the impaction axis, an internal angle of less than 12.degree., the inner surface of the half-shell comprising portions mating with the sections and forming in cross-section, with the impaction axis, an external angle substantially equal to the internal angle.

摘要： A modular hip stem prosthesis including a hip stem with an integral, enlarged shoulder and a neck section mountable to the hip stem. The integral, enlarged shoulder is designed to closely conform to the metaphyseal region to securely mount the hip stem in the end of the femur. The enlarged, shoulder portion of the hip stem is also selectively configured to be fabricated as a separate element so as to allow one of a plurality of distal stems to be mounted to the enlarged shoulder to create the hip stem. The neck section readily adapts the hip stem prosthesis for repair and replacement of the components of the total hip replacement without requiring replacement of the hip stem.
