Abstract
A two-piece intramedullary nail is provided having a stem portion and a rod portion. The distal and proximal ends of a femur are compressingly secured by the intramedullary nail by lag screw threads at the stem portion and a stepped portion at the proximal end of the intramedullary nail. A groove and key fit up between the stem portion and the rod portion prevents rotation of the two parts of the intramedullary nail. Elongated slots within the rod member and the stem member provide for openings through which fastening devices may easily be located and passed therethrough in order to secure broken fragments of the femur to the femur. An opening in the proximal end of the intramedullary nail provides for fit up of a hip plate and screw prosthesis or a femoral head hip prosthesis while providing structural support to the cylinder to plate connection thereof.
