Between January 1987 and December 1989, at the Department of Trauma Surgery of the University of Erlangen 41 patients were treated at one or both hips with the uncemented hip replacement "Erlanger Modell" including a special supporting ring because of the bad condition of the bone surrounding the acetabular region. In 41 cases the implantation was a revision. 2 patients have not been operated on before. They suffered from congenital hypdysplasia with severe bone destruction at the area of the acetabulum. The supporting ring and the cup are made of the titanium alloy TiAl5 Fe2.5. Using the supporting ring, it is possible to fix the socket within the bone graft and to diminish the pressure exerted on the socket by transferring a lot of stress directly to the iliac bone and the oubic bone. The results of 41 patients (43 joints) ranging from 21 to 57 postoperative months giving an average of 32 months, are very encouraging. 76.6% of the patients feel no or not much pain, 67.4% can walk without hooked stick and 79% can walk a distance of more than 1000 m. The range of movement of the hip joint could be improved, especially abduction and extention. Good results based on patients satisfaction were obtained in 95.4%.
1987年1月至1989年12月期间，在埃尔朗根大学创伤外科，41例患者因髋臼区域周围骨质状况不佳，接受了使用“埃尔朗根模型”非骨水泥型髋关节置换术，该置换术包括一个特殊的支撑环，其中41例植入手术为翻修手术。有2例患者此前未接受过手术，他们患有先天性发育不良，髋臼区域有严重骨质破坏。支撑环和髋臼杯由钛合金TiAl5 Fe2.5制成。使用支撑环，可以将髋臼固定在骨移植物内，并通过将大量应力直接传递到髂骨和坐骨，减少施加在髋臼上的压力。41例患者（43个关节）术后21至57个月（平均32个月）的结果非常令人鼓舞。76.6%的患者感觉无疼痛或疼痛轻微，67.4%的患者无需拄拐行走，79%的患者能够行走超过1000米的距离。髋关节的活动范围得到了改善，尤其是外展和伸展。基于患者满意度获得了95.4%的良好结果。
