Abstract

The intramedullary nail system includes an intramedullary nail (19) for insertion in the femur. The nail has an axial bore (31, 32, 34) and an intersecting transverse bore (33). A lag screw (49) is inserted through the transverse bore and turned into the head of the femur. A slotted sleeve (3) is inserted over the lag screw and through the transverse bore with the slots (9) aligned with the axial bore. A sleeve lock (2) is inserted into the axial bore and has a locking tab which engages the slots in the sleeve preventing rotational and longitudinal movement between the sleeve and the nail. A compression screw (6) is turned into the trailing end of the lag screw and engages the encircling sleeve to provide longitudinal translation between the lag screw and sleeve to apply compressive force across a fracture.
