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.
