In order to evaluate the long-term effect of total hip replacement (THR) in patients with steroid-induced femoral head necrosis, 40 cases of 50 hips received THR patients were followed up for an average of 8.5 years after operation. Evaluation was carried act according to Harris score system. In these cases, average score was seventy-five points. Revision rate among them was 2% after four years and 18% after five to eight and a half years, with as overall rate of 20%. It was found that the main reason for revision was looseness of the prosthesis. In this follow-up, it showed that besides foreigen body reaction, abnormal osseous remodelling was the main factor in long-term failure of this arthroplasty. It was also proved that it was a good selection to perform cemented total hip replacement in younger patients, which could improve living quality.
为评估全髋关节置换术（THR）治疗激素性股骨头坏死患者的长期疗效，对50髋接受THR的40例患者术后平均随访8.5年。依据Harris评分系统进行评估。这些病例中，平均评分为75分。其中4年后翻修率为2%，5至8.5年后为18%，总体翻修率为20%。发现翻修的主要原因是假体松动。此次随访表明，除异物反应外，异常骨重塑是该关节置换术长期失败的主要因素。还证明对年轻患者行骨水泥型全髋关节置换术是一个不错的选择，可提高生活质量。
