Abstract
A hip joint prosthesis has an external metal shell, an internal socket insert in which a ball head can rotate. The ball head is joined to a metal prosthesis shaft of the femoral shaft component and the movement of the prosthesis shaft is limited by abutting against the margin of the socket insert. A soft, biocompatible cushioning element is applied to the socket insert on the circumferential surface of the prosthesis shaft.
