HIP FRACTURE DEVICE WITH STATIC LOCKING MECHANISM ALLOWING COMPRESSION

摘要

In one embodiment, the present invention is a method of fusing fractures of a femoral neck using a bone plate including the steps of: placing a bone plate on the femur; inserting an assembly of a bone screw and a locking ring in an opening in the plate; simultaneously threading the locking ring and the bone screw in the femur; threading the bone screw in the femur to compress the fracture; creating a space between the locking ring and the bone screw; and allowing the bone screw to move towards the locking ring when the femur is loaded. In another embodiment, the present invention is a bone plating system including a bone plate having a plurality of openings; at least one bone screw capable of being received through the opening and into a bone; at least one end cap fixedly insertable in the opening; and a layer of polymeric material interposed between the end cap and the top of the head.
