Endoprothetik bei hüftgelenknahen Femurfrakturen

Abstract

The incidence of proximal fractures of the femur will increase with the demographic change in the German population. Besides osteosynthesis, which in most cases of femoral neck, pertrochanteric and femoral head fracture is the method of choice, arthroplasty of the hip is likewise an established therapy. Indications are dislocated femoral neck fractures of the elderly. But there are good results for arthroplasty after proximal femoral fractures in younger active patients as well, when the fracture was not recognized or treated immediately. The outcome of hip arthroplasty after fracture is influenced by the elderly and unhealthy patient himself and the difficult planning and operation conditions due to fracture and its morphology. Most important for the best result are an interdisciplinary preparation of the patient and a well-planned surgery. In these cases common complications like thromboembolism, massive intraoperative blood loss and general infections like urinary tract infection can be reduced. For hip arthroplasty after fracture total hip replacement as well as hemiarthroplasty with bipolar prosthesis should be considered. The implant chosen and the implantation technique with or without bone cement has to be determined. Facts like the general state of health, biological age, level of activity and comorbidities should be taken into account appropriately.
