Abstract
An implant for fixing two bone fragments to each other comprises a clasp (4) with two arms (7) which are connected to each other at one of their ends and in this area form an eyelet with an opening (8) for passage of a screw (6) which can be screwed into one (3) of the two bone fragments. The free ends of the two arms (7) are introduced into the medullary cavity of the other bone fragment (2) and are anchored therein by spreading apart. To improve the anchoring of the clasp (4) on the bone fragment (3), a shim part (5) is arranged between the clasp (4) and the head (9) of the screw (6), which shim part (5) has a recess for receiving the clasp (4) and is provided with spikes (11) which penetrate into the bone fragment (3).
