Abstract
An anchoring element for implantation in bone or other tissue takes the form of an externally threaded screw, for example of titanium or other tissue compatible material. Such an anchoring element may be used, for example for holding prostheses or artificial joint components. To increase its rotational stability and prevent the element from becoming unscrewed, the threads of the screw are provided with notches, for example by forming spiral or straight grooves in the peripheral threaded surface of the element, which grooves intersect the thread turns to form these notches. After such an anchoring element has been implanted in bone tissue for example, the tissue draws into the notches to provide keys preventing rotation and unscrewing of the anchoring element.
