摘要
目的探讨全髋关节置换术(THA)后早期人工关节脱位的原因与防治措施。方法对212例(224髋)采用后外侧入路行THA术患者中术后3个月内出现人工关节脱位的5例进行回顾性分析。结果本组5例患者中4例为初次THA,1例为翻修;脱位均经闭合复位、下肢皮肤牵引或石膏固定6周,4例获得稳定,1例反复脱位并发生人工关节松动,翻修后获得稳定。结论 THA术后人工关节早期脱位的主要危险因素包括软组织失衡、人工关节位置不良以及术后体位失当等。闭合复位、皮肤牵引或石膏固定6周是有效的治疗方法,复发性脱位患者可通过手术翻修获得稳定。
Objective To investigate the causes and managements of the early dislocation after total hip arthroplasy （THA）.Methods Two hundred twelve patients（total 224 hips）had the THA surgery by posteriolateral approach.There were 5 early hip dislocation cases after surgery,which were included in the study.Results Five dislocation cases were in 3 month after surgery,4（80%）of them were primary THA cases and 1（20%）was revision case.Closing reduction and 6 weeks immobilization were performed for these patients.4 cases were successful.However,one patient had recurrent dislocation,and the prosthesis was loosened from the bone.It was got stable after revision.Conclusions Misbalance of the soft tissues,improper placement of the prosthesis,and malposture were the surgery risk factors for early dislocation after THA.Closing reduction and immobilization for 6 weeks are usually successful in most of the dislocated cases.If not success,revision could be done to achieve a stable joint.
