ABSTRACT:
The acetabular cup prosthesis has a metal socket having a socket shell for receiving a spherical joint head as well as a plastic ring which covers the equatorial edge surface of the metal socket and which has an inner diameter corresponding to the inner diameter of the shell. In the event of a dislocation of the joint head, the polished surface of the joint head contacts the plastic ring to deform the ring without imposing a point load on the metal joint head.
