Résumé : The short- and long-term results of surgical treatment of fractures of femoral neck were analyzed in 140 patients older than 75 years. (135 Thompson prostheses, 5 internal fixation Garden I). The poor medical conditon at admission (72% of the cases) and the social situation of these elderly patients explained the numerous general complications (62% of the patients) and the mortality of 18% at one month, 31% at three months and 44% at one year. Review of 45 patients, with a 44 months mean follow-up, showd that 79% had a good functional result. Three of 6 patients who had developed severe pain required a total hip arthroplasty. The frequent painful acetabular erosions occurring during the 4 postoperative years suggest that Thompson hemiarthroplasty should be reserved for the older patients. The best treatment of Garden I and II fractures is internal fixation which also allows immediate weight bearing. For the other patients, it must be proven that a bi-articular prosthesis is better than a Thompson prosthesis. In elderly patients, primary total hip arthroplasty is rarely indicated.
