An angled variable cephalometric nailing system for treating a femur fracture, an instrument used to place the system, including a valgus-producing osteotomy device within the scope of the present invention

摘要

The cephalomedical nailing system of the present invention is a three-part modular nailing system that includes three types of reduction: reduction of fracture, improvement of assembly biomechanics so that the load axis is possible for the fracture line, and collapse of the femoral neck as well as prevention of offset and rim length loss Avoiding the possibility of reducing abduction power by being able to be used to solve major problems. The system can rotate the nail 360 ° and facilitate the insertion of the nail through the thread, based on the geometry of the particular threaded channel and the arrangement of the additional fastening screws.
