The bone anchoring portion comprises at least one flexible wing that is adapted to selectively fix the graft pulley within a bone tunnel. At least one wing is adapted to flex during insertion into a bone tunnel and then resist flex and thereby resist movement back out of the tunnel and hence wedge itself within the tunnel. The graft instrument may be selectively attached to the graft pulley and includes a handle and elongate body, adapted to insert the graft pulley into the selected bone tunnel. Once the graft pulley is in place, the placement instrument may then be detached and withdrawn leaving the graft pulley firmly fixed within the bone tunnel and can then be used to position a ligament graft. | 05-19-2011 |
