ABSTRACT:
An intramedullary hip screw is provided which includes an intramedullary rod, a lag screw and a sleeve for slidably receiving the lag screw. The sleeve is received in a passage in the intramedullary rod having an axis positioned at an angle relative to the longitudinal axis of the intramedullary rod such that the axis of the sleeve is directed toward the head of the femur. The intramedullary hip screw of the present invention permits sliding compression of selected fractures, particularly intertrochanteric fractures and fractures of the femoral neck.
