Abstract

A hip fracture device providing distance limited dynamization, load controlled dynamization and combinations of both dynamization methods by varying components. The components may be varied interoperatively. A bone plate having a plurality of openings for receiving a compression bone screw or a cortical screw. An end cap, threadably insertable in the opening and having a layer of polymeric material interposed between the end cap and the top of the head such that the compression of the polymeric material would allow slight axial movement of the screw. Alternatively, a locking ring adapted to attach to the head of the screw and having ridges that have shape complimentary to the depressions and fit in the depressions when the locking ring is attached to the head.
