ABSTRACT:
A connector for treatment of a fractured femur neck consists of an intramedullary nail to be inserted into the bone cavity through a bore made in the trochanter region. The leading or front end of the nail is provided with an expandable portion that can be urged against the cavity walls of the bone until it is held therein in a firm grip. This operation is carried out by manipulation of a screw in the rear portion of the nail which projects out of the bone by a short length. The rear end of the connector is fastened to the shaft of the femur by means of a flat fixator plate which is firmly fastened to the bone material by screws on the one hand, and to the connector by a socket adapted to be moved along the rear end by a screw-thread connection. The two fractured bone parts are drawn together and held in close attachment by pulling the fixator plate, together with the shaft portion towards the front end of the connector which has been expanded previously and clamps the neck in a firm grip.
