An anchoring system (S) for mounting a support plate (P, P') for instance to a human rachis comprises first and second threaded fasteners (10, 20) each having proximal and distal ends. The proximal ends are adapted to be spaced from each other for holding the support plate (P, P') against a vertebra (V, V1, V2) of the rachis while the distal ends are embedded in the bone. The threaded fasteners (10, 20) converge from their proximal ends towards their distal ends. The first threaded fastener (10) defines at its distal end a female threaded element in the form of a threaded openig (12) extending obliquely means of the first fastener (10) and adapted to be threadably engaged by the male threaded distal end of the second fastener (20). The proximal end of the first fastener (10) is provided with indicia for indicating an orientation of its threaded opening (12) within the bone (V, V1, V2) such as to facilitate the engagement therein of the male threaded distal end of the second fastener (20). With the support plate (P, P'), the first and second facteners (10, 20) define a triangular frame that is firmly secure to the vertebra (V, V1, V2). |
