Abstract
Joint prostheses, in which one joint partner is formed as a socket and the other joint partner is formed as a spherical head which is rotatably mounted in the socket, are known in particular as shoulder-joint and hip-joint prostheses. The force-fit connection, in particular conical jamming, is also used here as the connecting technique between metallic or ceramic spherical heads and the cone. A coupling element (6) is inserted between the cone (5) and the spherical head (3) of the force-fit connection (1). The elasticity and damping properties of the coupling element (6) can be predetermined by its porosity and the structure of its surface.
