初次复杂全髋关节置换术旋转中心重建策略及临床疗效分析

Strategy and clinical analysis of initial complex total hip arthroplasty rotating center reconstruction

目的探讨初次复杂全髋关节置换术旋转中心重建策略并对其临床疗效进行分析。方法采用病例-对照研究,对418例患者进行回顾性分析,分析髋臼假体旋转中心与解剖旋转中心符合率及术后假体旋转中心的误差对临床疗效的影响。结果 Haris评分由术前平均(43.5±5.3)分增加至末次随访(87.4±3.2)分。恢复至理想旋转中心者为(96.4±3.2)分。结论恢复髋关节正常的旋转中心是置换后临床疗效的重要影响因素之一。

Objective To investigate the strategy of initial complex total hip arthroplasty rotating center reconstruction,and to analyze its clinical efficacy.Methods With a case-control study,418 cases of patients were retrospectively analyzed.The coincidence rate of acetabular prosthesis rotating center and anatomy rotating center,and the influence on clinical curative effects of postoperative prosthesis rotating center errors were analyzed.Results The Haris score increased from preoperative mean（43.5±5.3） scores to latest follow-up（87.4±3.2） scores.The scores of those patients who restored the ideal rotating center were（96.4±3.2） scores.Conclusion The restoration of normal rotating center of hip joint is one of the important factors to affect the clinical efficacy after replacement.
