Abstract
An implant for fixing bone fragments after an osteotomy, especially for treating the misalignments of a metatarasal bone, includes a clasp with two arms and a screw. The arms are connected to each other at one end so that they form a screw eyelet adapted to receive the screw. The arms are configured to be introduced into the medullary cavity of a first bone fragment, and the screw is configured to be inserted a second bone fragment. The clasp is made of an elastic material, so that in a relaxed state the distance between the arms increases toward their free ends. The clasp is configured for being introduced into the medullary cavity of the bone fragment in a compressed state, so that after insertion the arms spread open and secure the clasp in that bone fragment.
