Between March 17, 1984 and August 20, 1987, 142 patients with osteoarthritis of one or both hips were treated by joint replacement with the uncemented "Erlangen" hip prosthesis (Prof. H. Beck/P. Brehm Chirurgie-Mechanik GmbH). The causes of the osteoarthritis varied. Hip replacement was carried out for the following conditions: rheumatoid arthritis including ankylosing spondylitis, aseptic necrosis of the femoral head, including posttraumatic and idiopathic forms, osteoarthritis of unknown origin, osteoarthritis following dysplasia or subluxation of the hips, and loosened cemented hip prostheses (131 primary implantations and 19 revisions). Full weight-bearing was not permitted for 50 days postoperatively, but mobilization and isometric exercises were started 2 days after operation and isotonic exercises were introduced later. Complications included fracture of the femoral shaft during operation and aseptic loosening. Our results in the 142 patients (150 joints) at 32-65 months (average 44 months) after surgery are encouraging. Good results based on patient satisfaction were obtained in 92.7% (81.3% after revision) and poor results in 7.3% (18.7% after revision). Most (90.2%) of the patients can walk without a stick (50.0% after revision), and 90.2% of the patients can walk more than 1000 m (68.8% after revision).
1984年3月17日至1987年8月20日期间，142例单髋或双髋骨关节炎患者接受了非骨水泥型“埃尔朗根”髋关节假体置换手术（H. 贝克教授/P. 布雷姆骨外科机械有限公司）。骨关节炎的病因各不相同。进行髋关节置换的情况如下：类风湿关节炎包括强直性脊柱炎、股骨头无菌性坏死，包括创伤后和特发性类型、不明原因的骨关节炎、髋关节发育不良或半脱位后的骨关节炎以及松动的骨水泥型髋关节假体（131例初次植入和19例翻修）。术后50天内不允许完全负重，但术后2天开始进行活动和等长运动，随后引入等张运动。并发症包括手术期间股骨干骨折和无菌性松动。我们对142例患者（150个关节）术后32至65个月（平均44个月）的结果令人鼓舞。基于患者满意度的良好结果在92.7%（翻修后为81.3%），不良结果在7.3%（翻修后为18.7%）。大多数（90.2%）患者可以不用拐杖行走（翻修后为50.0%），90.2%的患者可以行走超过1000米（翻修后为68.8%）。
