  • Modular intramedullary fixation system and insertion instrumentation
    Patent number: 6168595
    Abstract: An intramedullary nail for use in combination with a proximal bone screw. The nail includes an elongated body having a proximal end and a distal end with a central axis extending between the proximal end and the distal end. The proximal end of the body has a transverse slot therethrough, the transverse slot therethrough with contour for allowing the proximal bone screw to be inserted through the transverse slot and through the proximal end of the body with the longitudinal axis of the proximal bone screw located at an angle to the central axis of the body of the nail within a range between an acute angle on either side of a plane extending transverse to the central axis of the body of the nail.
