Abstract
An anchoring screw (1) is disclosed for implantation in bone, consisting of a tissue compatible material for supporting prostheses, artificial joint components, or the like. The anchoring screw (1) has at least one slot (5, 5a) extending from its threaded outer surface at a distance from the insertion end (3). The slot (5, 5a) is arranged to receive a blanking element (6, 6a) which shields the slot (5, 5a) during the application of the anchoring screw (1) and its integration in a recess prepared beforehand in the bone during a healing stage. The blanking element (6, 6a) is replaced, after integration of the anchoring screw (1) with the bone, by a holder for a prosthesis, the holder including a web portion insertable into said slot. There is also disclosed an anchoring arrangement comprising at least one such anchoring screw and such a holder or coupling, and a method for application of such an anchoring arrangement in osseous tissue.
