Abstract

Acetrabular cup as part of a hip joint prosthesis is composed of an outer support ring and a plastic inner socket insertable into the support ring. The acetabular cup includes a covering cap provided with at least one metal surface which covers the part of the inner socket not surrounded by the support ring and whose metal outer contour supplements the socket to give it the spherical shape of an essentially closed hemisphere or spherical cap.
