Proximal femoral fractures in conjunction with hemiarthroplasty according to Moore

During a period of six years, 245 hemiarthroplasties according to Moore were implanted for fractures with dislocation of the femoral neck. In five patients (2%) proximal ipsilateral fractures of the femur occurred in the postoperative phase. All fractures were located near the tip of the prosthesis. Four were spiral fractures, one was a communitive fracture. Four patients were treated with plating, one with screw fixation. Two patients were unable to walk, two patients were able to walk with help and one walked without help. Classification of fractures distal to an endoprosthesis and operative modalities are discussed.
