摘要：
A bone plate screw-blocking system and method that comprises a plate with at least two bone screw receiving holes, blocking elements, bone screws, and a tool capable of simultaneously actuating at least two blocking elements. The plate includes an upper surface and a lower surface with bone screw receiving holes that extend through both surfaces of the plate. The bone screws couple the plate to the bone via the bone screw receiving holes. The blocking elements are movably positioned proximate each bone screw receiving hole. In an initial unblocked position, the blocking elements do not cover the bone screw receiving holes. Upon movement into final blocked positions, the blocking elements cover at least a portion of the bone screw receiving holes and preferably extend over at least a portion of the bone screw during use.
