ABSTRACT:
The hip joint socket has a plastic socket body which is covered on the outer surface with a multi-layer grid and which is provided with a plurality of peg-like projections of metal which are welded into the plastic socket body. The use of the metal projections and the metal grid prevent direct contact between the pelvic bone and plastic socket body in order to avoid disintegration of the plastic body by body fluids. The welding in of the projections provides a cost effective and small labor-intensive fixation of the projections in the socket body while ensuring firm and secure anchoring.
