Claim Text:
1. A rotary joint prosthesis comprising a first component for anchoring to a first bone, a second component for anchoring to a second bone, and a coupling piece which, with the first component, forms a flexion bearing about a first axis and, with the second component, forms a rotary bearing, formed by a pin and bearing bush, about a second axis oriented transversely with respect to the first axis, wherein the rotary bearing comprises a multi-layer bearing insert with a sliding sleeve surrounding the pin and a support sleeve that encloses said sliding sleeve and is fastened to the coupling piece by a securing element, wherein the securing element has an actuation member within the support sleeve and is configured to be connected to the coupling piece to ensure tensile strength via two aligned bores in the support sleeve and the coupling piece.
