VARIABLE-ANGLE LOCKING SCREWS, AND BONE PLATE SYSTEMS THAT INCLUDE THEM

摘要

A bone plate system includes variable-angle locking screws and a bone plate, and optionally non-locking screws and/or standard locking screws. The bone plate has threaded holes and may have non-threaded holes. The variable-angle locking screws have a threaded shank and a threaded head. The threading on the head is discontinuous, which allows the variable-angle locking screw to be inserted into a threaded hole on the plate at an angle relative to the axis of the threaded hole.
