ABSTRACT:
A device for attaching a prosthesis including a metal foundation provided with a plate integrally formed with at least one anchoring pin consisting of elastically deformable wings and at least one the screw cooperating with a nut. The screw goes through the pin, to spread the wings into a position away from a longitudinal axis of the pin. The anchoring pin comprises an internal bore having a cylindrical base connecting the pin to the plate, and a circular counter-bore adjacent the bore of greater diameter than the internal bore of the pin, making it possible to spread the wings while maintaining their rigidity over their entire length.
