Abstract
The prosthesis stem is provided with a recess on each side having boundary walls concentric to a common center of curvature. Each recess receives a molding which carries a wire mesh structure for the invasion of bone tissue after implantation. Bending of the proximal zone of the stem occurs without movement of the molding so that shear stresses are not imposed upon the bone tissue invading the wire mesh. A peg-like projection on each molding fits with a clearance in a further recess in the metal stem to avoid accidential sliding out of each recess.
