摘    要:目的评价应用大直径陶瓷/陶瓷股骨头人工全髋关节置换术治疗股骨头缺血坏死的临床疗效。方法回顾性分析本组3年内收治的23例股骨头缺血坏死患者实施单侧大直径陶瓷/陶瓷股骨头人工全髋关节置换术,患者手术时平均年龄53.5岁。平均随访26个月,手术前后评估患者髋关节Harris评分,术后进行X线检查评价假体位置情况及主观满意度调查。手术前后及随访时监测患者肾功能的变化。结果所有患者均获得随访,在随访期内影像学显示假体位置良好,无假体松动,脱位等并发症。Harris评分由术前50.7分改善为术后91.2分,优良率为95.7%,总体满意率为95.7%。手术前后及随访时患者肾功能无明显变化。结论大直径陶瓷/陶瓷股骨头全髋关节置换术治疗股骨头缺血坏死可获得较好的安全性和近、中期疗效。

Abstract:Objective To assess the clinical effects of the total hip arthroplasty(THA) with large diameter ceramic-ceramic femoral head prothesis in treatment of avascular necrosis of the femoral head.Methods In three years,23 patients,with mean age of 53.5 years,underwent total hip arthroplasty with large diameter ceramic-ceramic femoral head prothesis.The mean follow-up period was 26 months.Harris score,X-ray test,subjective satisfaction survey,and kidney function were examined before and after operation.Results The protheses position of all the patients remained well during follow-up period.No complications like loosening and dislocation occurred.The Harris score was increased from 51 before operation to 91 after arthroplasty.The excellent rate and total satisfactory rate were both 95.7%.No obvious change occurred in the kidney function before and after the operation.ConclusionsGood short-term effects can be achieved using large-diameter ceramic-ceramic femoral head prothesis in THA for avascular necrosis of the femoral head.
