Abstract: A bone plate system comprises a bone plate including a first surface and a second surface, the bone plate including at least one threaded aperture, the threaded aperture being tapered between the first surface and the second surface. The bone plate system further comprises at least one fastener including an elongate shaft and a threaded head, the threaded head being tapered between a proximal end of the threaded head and a distal end of the threaded head, wherein a plurality of circumferentially spaced recesses are formed in the threaded head and define a plurality of threaded tabs. The at least one fastener is configured for insertion within the at least one threaded aperture at a plurality of different insertion angles while achieving a locking engagement between the threaded head and the threaded aperture.

Abstract: The present application is directed to self-locking surgical fasteners. The fastener generally includes a shaft section, a head section, and one or more locking members. The locking members may be located within the head section. A first portion of the locking members may extend beyond an outer surface of the head section, and a second portion of the locking members may extend into a hollow interior of the head section. A tool used to insert the fastener into the patient engages a receiver portion of the fastener. As the insertion tool engages the receiver, the tool may contact and exert a force on the locking member such that the first portion of the locking member may be retracted within the head section. Upon disengaging the insertion tool from the receiver, the locking member may return to the position extending outward beyond the outer surface of the head section.
