One hundred and ninety-six cemented total hip arthroplasties performed in 190 patients (mean age, 62 years) followed-up with an average of 8.7 years were reviewed. The results were compared with the same group previously reported at an average follow-up of 4 years. Clinically satisfactory results were observed at the short- and medium-terms. Evaluation of the study with Harris score system showed that the score records fell from 85 to 78.4 points in the same group and the revision rate rose from 6.84% to 14.73%. The main causes of the prosthesis failure were loosening of the prosthesis and of breakage of the prosthesis stem. This follow-up study showed that the short-term prosthesis failure was mainly related to the cement-fixing technique, while the medium-term failure was due to side effects of the cement. This series showed that cemented prosthesis is a good selection especially for elderly patients.
回顾了190例患者（平均年龄62岁）接受的196例骨水泥型全髋关节置换术，平均随访8.7年。将结果与之前报道的同一组患者平均随访4年的结果进行比较。短期和中期观察到临床满意的结果。用Harris评分系统对该研究进行评估显示，同一组患者的评分记录从85分降至78.4分，翻修率从6.84%升至14.73%。假体失败的主要原因是假体松动和假体柄断裂。这项随访研究表明，短期假体失败主要与骨水泥固定技术有关，而中期失败是由于骨水泥的副作用。该系列研究表明，骨水泥型假体是一个很好的选择，尤其对于老年患者。
