Implantable orthopaedic device composed of a support structure having at least one orifice associated with a nut, for the passage of a locking screw

摘要: This implantable orthopaedic device comprises a support structure (2) having an orifice (3) that delimits seat (5) for receiving nut (6) intended to cooperate with locking screw (4). The upper part (5a) and lower (5b), both shaped as truncated spheres concentric each other. Furthermore, the has spherical contour (11), head (15) (15b), also contour, (15a) provided thread (17). (15b) parts of respectively complementary (14) (5b) such that, in final phase screwing, they tend move said away from thus bring about forced bearing (11) against (5), (5).
