Abstract
With the invention a mounting system is shown for metallic support shells at implantable joints with pin-like metallic anchoring elements. The anchoring elements have a head which lies on a shoulder of the implant in the axial direction. Between the shoulder and the head there is a circular sealing edge. A contact pressure force is produced on the head by a contact pressure generating screw which is so great that a metallic seal is produced through plastic flow at the scaling edge which is liquid-tight and prevents the intrusion of abraded particles from the inner region of the support shell.
