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.

Abstract: Combination apparatus for a total hip replacement or compression and fixation of the femoral head to a femur is provided. A compression plate is provided with a strut member extending between the barrel of the plate and the lower portion of the plate to significantly reinforce the connection of the barrel to the plate. The barrel is alternatively utilized with a compression screw apparatus or total hip replacement apparatus.

Abstract: Apparatus for wire wrapping or tying is disclosed, wherein an inner sleeve is telescopically positioned within an outer sleeve, each of which is provided with a handle for imparting relative rotational movement. The wire tie apparatus is adapted to receive wire which is wrapped an object to be tied. The wire passes through the outer sleeve then through the inner sleeve. Apparatus is provided to fricitionally lock the wire at some point along the length of the inner sleeve. Rotation of the inner sleeve relative to the outer sleeve in accordance with specially prepared ends of both the inner and outer sleeves causes the wire to twist and to become wrapped tightly around the object to be wrapped. Further relative rotation causes inelastic extension of the wire and subsequent breakage of the same somewhere along the length of the twisted portion thereof.

Abstract: An implantable compression hip screw is disclosed. A unique antirotational/locking device used in combination with axially aligned grooves in a barrel plate and a lag screw prevents the fractured portion of the femur from rotating during the postoperative period. The antirotational/locking device comprises elongated rods which fit within the aligned grooves and thereby allow sliding of the lag screw relative to the barrel plate during the postoperative period.

Abstract: Compression hip screw apparatus comprising a lag screw, a hip plate, a compression nut and a locking assembly. The lag screw is inserted through the barrel of the hip plate after the hip plate is installed which eliminates the need to find a lag screw buried within the femur. Keyless construction further aids assembly. The locking assembly frictionally locks together the lag screw, the hip plate and the compression nut.

Abstract: An improved abduction pillow is disclosed for post-surgical immobilization of a patient's hips and legs. The pillow includes a removable and replaceable portion for sanitary reasons and which permits access to the patient's pelvic area while maintaining hip and leg immobilization. Spare removable portions are stored within the pillow. A soft foam outer covering increases patient comfort and further enhances cleanliness. Catheter channels are provided in the removable portion of precise orientation of a catheter inserted in a patient. The main portion of the pillow is equipped with structural apparatus for attaching convenience items such as a table, tray, radio, etc., to the pillow.

Abstract: A prosthetic device for repairing or replacing joints of skeletal bones such as the acetabulum is attached in a new manner by a force fit in the prepared bone void of the acetabulum. The prosthetic device includes a frusto-conical shaped hollow cup which is force fitted into the prepared bone void and carries a stop flange to prevent further penetration of the bone void. A hollow plastic liner is housed within the cup.

Abstract: A bone implant fixation plate having an angled bend intermediate its ends provides improved structure for fixation of the greater trochanter to the femur. Hollow pins are fixed to the intermediate bend for fixation in drilled holes in the greater trochanter by a flaring tool.

Abstract: An implantable prosthetic bone device which incorporates an improved prestressed anchoring means to provide reinforcement and replacement for fractured or diseased bones and joints.

Abstract: An improved pretensioned prosthetic device is disclosed which incorporates pretensioned or biased spring means to provide a skeletal joint such as a finger or knee joint with a controlled flex and reflex action.
