One hundred and three patients with non-traumatic osteonecrosis of the femoral head had 144 primary total hip replacements performed. Average age was 47 (22-73) years. In 85 cases a cemented prosthesis, and in 45 cases an uncemented prosthesis was used, while 14 cases had a cemented femoral stem and an uncemented cup. At follow up, 25 patients had died, 13 patients had had a revision of the prosthesis, and two patients were lost to follow-up, leaving 63 patients (92 hips) for clinical and radiological evaluation. Kaplan-Meier plots for survival of the prosthesis were constructed, showing a total risk of failure of 8% at five years, increasing to 16% at seven years. In 89% of the patients without concomitant diseases, the clinical result was excellent or good. There was no difference in the clinical or radiological result in patients with cemented and uncemented prostheses. It is concluded, that the result after total hip replacement due to non-traumatic osteonecrosis of the femoral head is comparable to that of total hip replacement due to osteoarthrosis, and that an uncemented prosthesis can be expected to yield a result comparable to a cemented prosthesis.
103例非创伤性股骨头坏死患者接受了144次初次全髋关节置换术。平均年龄为47岁（22 - 73岁）。85例使用骨水泥型假体，45例使用非骨水泥型假体，14例采用骨水泥型股骨柄和非骨水泥型髋臼杯。随访时，25例患者死亡，13例患者进行了假体翻修，2例患者失访，剩余63例患者（92髋）进行临床和影像学评估。构建了假体生存的Kaplan-Meier曲线，显示五年时假体总失败风险为8%，七年时增至16%。在无合并症的患者中，89%的临床结果为优或良。使用骨水泥型和非骨水泥型假体的患者在临床或影像学结果上无差异。得出结论，非创伤性股骨头坏死行全髋关节置换术后的结果与骨关节炎行全髋关节置换术的结果相当，并且预期非骨水泥型假体可产生与骨水泥型假体相当的结果。
