Efficacy of total hip replacement with cement and cementless system for femural neck fracture

目的 :股骨颈骨折患者行人工全髋关节置换术治疗时非骨水泥型与骨水泥型的疗效对比。方法 :应用瑞典米他保公司人工髋关节假体及手术器械 ,对 72例股骨颈骨折患者施行全髋关节置换 ,其中非水泥型人工全髋关节 53例 ,水泥型 1 9例。临床随访根据Harris的评分方法进行评分。结果 :临床随访 Harris评分术后 3年平均 95分 ,5年平均 89分 ,7.5年平均 83分 ,Harris评分低于 85分者 6例。术后 2例髋臼假体松动 ,但仅限于 X线所见 ,临床上尚无症状 ,3例术侧肢体深静脉栓塞 ,经溶栓、抗凝治疗后症状消失。目前尚无行翻修手术的病例。结论 :应用人工全髋关节置换术 (THR)是治疗股骨颈骨折的有效治疗手段 ,其疗效显著 ,并发症少 ,很大程度改善了病人关节功能 ,提高了术后生活质量。

Objective:Compare the curative effect of total hip replacement (THR)implanting with cement and cementless system.Method:72 patients have been treated by THR with Mitabao total hip system including the implants with cement (19 cases)and cementless systems (53 cases).All case were followed up for 6 to 9 years and assessed by Harris-Score. Result: Three years after operation the average score is 95 , 5 years later the score is 89 and the score is 83 after 7.5 years, In only 6 cases the score is lower than 85 . 2 cases were found prosthesis loosen but have no clinical symptom .
