Abstract

Bone plate system, including methods and apparatus, for attaching a fastener to a bone plate at a selectable angle. In an exemplary method, a bone plate and a fastener may be selected. The bone plate may define an aperture having an internal thread. The fastener may include a proximal region and a distal region. The proximal region may be tapered conically toward the distal region. The fastener may be disposed in the aperture and in bone, such that the serrated thread is cross-threaded with the internal thread to create an interference fit and locked engagement of the proximal region with the aperture.
