老年人人工髋关节翻修术临床分析

Clinical analyis of Artificial hip joint revisions in eldery Patients

目的：观察采用微孔涂层非骨水泥髋关节假体和骨水泥固定假体，对失败的髋关节假体翻修的近期效果。方法：采用微孔涂层非骨水泥髋关节假体和骨水泥固定假体，行老年人人工髋关节翻修术9例，并通过Harris评分进行疗效评价。结果：8例翻修术后得到随访。随访时间1～5年，平均2．5年；7例髋关节痛消失。关节功能恢复满意；翻修前Harris评分平均为42分，术后随访平均为85分。结论：髋关节翻修中采用微孔涂层非骨水泥髋关节假体和骨水泥固定假体，自体或异体骨移植修复骨缺损。达到了修复骨缺损和固定假体的目的，取得良好的近期效果，远期效果有待进一步观察。

Objective To observe the cases of THA revisions for loosened prosthesis, infected joint and acetabular defideney and the follow- up result to offer reference for THA revisions. Methods 9 cases with loosened hip component and bone defect were revi,sed by morselized bone auto/allografting and cement or noncement prosthesis. Results 8 THA patients who had received revisions were follow-up through the use of Harris scorns. Time of follow- up is from 1 to 5 years, Mean time is 2.5 years. There are 7 cases who present no pain except one case who take medicine to relief the interval pain and obtain satisfied function in hip joint. The average Harris＇ score was 42 before revision, and 85 after revision. Conclusions The fixation of the porous- coated or cement prosthesis in revisions have showed good result of bone defect reconstruction in short - term result, and observation is necessary for the long- term result.
