The prosthesis is composed mainly of two plates (110, 120) each equipped with anchoring flaps (1110, 1210) separated by a joint (20) composed of a spherical cap (21) with a cylindrical base (22), of the same diameter, made in the upper side of the lower plate (120). Each of the plates (110, 120) includes, on the back, threaded holes (115, 116, 125, 126) located parallel to the anchoring flaps (1110, 1210). |
