An implant (10) intended to the reinforcement and/or consolidation of bones and/or to the anchoring of tirefonds is configured like a pin so that it is expandable and/or swellable and/or lockable in another way into the bones. The implant (10) presents preferably on its outer face annular beads (16) and inside a female thread (20) enabling to screw the tirefonds. The implant (10) enables to improve the tensile strength when anchoring the tirefonds.
