ABSTRACT:
The joint socket consists of two parts, namely an outer split sleeve and a conical insert. The conical insert contains a hemispherical socket for receiving a joint head.
The outer surface of the sleeve is in the form of a truncated cone and is provided with depressions and ribs as well as longitudinal grooves. The ribs serve to penetrate into an artifically created socket bearing of a bone to insure a secure primary fixation in a cement-free anchorage. A firm securement of the socket is insured by the expansion of the sleeve and the penetration of the ribs into the bone.
