During 1978 to 1987 361 patients (312 female, 49 male) were treated with Variokopf-prosthesis (a bipolar hip prosthesis with a variable head) after femoral neck fracture, per- or subtrochanteric fracture. The mean age was 83 years. During postoperative treatment 73 patients (20.2%) died. 288 could be discharged. 98 of these died before the follow-up examination. The follow-up was possible in 103 cases. A good to satisfactory result was found in 91 cases (88%). A poor result in twelve cases (12%) (Score by Merle d'Aubigne et al.).
