 Using the traditional and hitherto used uncemented hip prostheses achieved good clinical results, but one of the drawbacks is the risk of fracture in the femoral shaft in indbankning of the prosthesis 1-2. In addition, the bone scan demonstrated that in the years after surgery dropped almost 30 of bone mass in the femoral shaft. This bone loss increases the risk that in the years after surgery, the increased risk of fractures around the prosthesis and in addition to impeding the described bone replacement prosthesis later.
