Abstract

The present application is directed to an implant maintained within the patient by a fastener. The implant includes an aperture sized to receive the fastener. A locking member extends across the aperture in a first position. The locking member is constructed of a resilient material that is movable to a second position during insertion of the fastener. Once the fastener is inserted within the aperture below a level of the locking member, the locking member rebounds towards the first position and extends over the fastener. The locking member prevents the fastener from backing out of the implant.
