ABSTRACT:
An anchoring element for supporting a joint mechanism is disclosed. The anchoring element is substantially rotationally symmetrical, at least partially hollow, and includes a material which is compatible with the tissue of a bone. The anchoring element has a surface which can be at least partially osseo-integrated with the tissue to achieve permanent endosteal anchorage in the longitudinal axis of the bone. The anchoring element is applied within the bone by: cutting the bone close to its joint to expose the marrow cavity of the bone; forming a space in the marrow cavity close to the joint; applying a guide sleeve in the space; and screwing the anchoring element into the marrow cavity while using the guide sleeve to center the anchoring element.
