Abstract: Apparatus in the form of a system for fixing fractures of the femur which includes a nail to be inserted in the proximal extremity of the femur. The fore end of the nail includes a plurality of prongs which tend to spread apart as the nail is inserted. A guide rod is initially inserted into the femur and is used as a guide for the nail during its insertion. A locating bracket is utilized to facilitate inserting of the guide rod. The nail is connected to a driving handle which is then manually operated to insert the nail in its correct position. A force applying device, which includes a turnbuckle assembly, is to be connected to the nail to facilitate removal of the nail after the fracture in the femur has healed.
