PERFECCIONAMIENTOS INTRODUCIDOS EN UN COLLARIN DE INTERCOLO-CACION PARA LA ESPIGA DE UNA IMPLANTACION DE HUESO PROSTETI-CA DE METAL.

摘要

A collar of a low modulus of elasticity material is interpositioned between the collar of a metal prosthetic hip stem implanted in the intermedullary canal of the femur and the adjacent calcar or outer edge of the bone. A flange depends from the insert between the upper portion of the stem and the inner wall of the bone. The interpositioned collar is either a full elongated tapered O-shape or it is open on one side of a tapered U-shape.
