发明名称 CONTROLLING BONE COMPRESSION
摘要 Systems, devices and methods are disclosed for limiting compression of a fracture imposed by a lag screw of a fixation system that includes a fixation device, a lag screw and a compression screw. The disclosed devices, systems and methods prevent over-compression of a fracture by a lag screw caused by over rotation of the compression screw. Specifically, implementations of a lag screw driver and a compression screw driver are provided whereby an engagement between the lag screw driver and compression screw driver prevents any further lateral movement of the lag screw, thereby providing a complete stop to further advancement of the lag screw and any additional compression.
