Abstract:
1. A method of anchoring a prosthesis structure to a joint end of an articulatory part of a joint in a human or animal body, said prosthesis structure comprising an engagement element which presents a flat or substantially flat engagement surface and an elongate fixture having a major axis and being connected to and spaced from the engagement surface, the method comprising the steps of: forming a flat or substantially flat joint end bone surface at said joint end; forming a bore through said joint end, wherein the bore has a longitudinal axis which inclines away from the joint end bone surface at an acute angle, and wherein the bore is provided at a distance from said joint end bone surface; forming a slot between the joint end bone surface and the bore; and inserting said elongate fixture along said major axis into the bore so that said engagement surface is brought into a first contact with said joint end bone surface at an intermediate insertion position; and further displacing the elongate fixture along the longitudinal axis of the bore to bring the engagement surface from the intermediate insertion position to a final anchored position.
