Abstract: A femur head implant has an oblique neck. A ball portion of a hip joint is connected to a first neck end. A femur head hollow portion is connected to a second end of the oblique neck. A tubular shell is connected to a lower end of the hollow portion. A slot in the tubular shell permits changes in the inside diameter of a femur shaft passage through the tubular shell. Screws are tightened to reduce the inside diameter and clamp the implant to a femur shaft that is received in the shaft passage and extends into the femur head hollow portion. Passages are provided in the hollow portion for the insertion of bone cement into the hollow portion and the escape of gas from the hollow portion.

Abstract: The tubular splint has a tubular shell with a slot extending from one end to the other. A first clamp bracket with a plurality of bores is fixed to the tubular shell adjacent to a first side of the slot. A second clamp bracket, with a plurality of threaded bores that are in substantially axial alignment with the plurality of bores in the first clamp bracket, is fixed to the tubular shell adjacent to a second side of the slot. A screw passes through each bore and screws into one of the plurality of threaded bores. A worm is journaled on one of the clamp brackets, engages a worm wheel on each screw and rotates all of the screws simultaneously. A wedge member can be secured to the bone and engaged by the shell.
