【摘要】 目的探讨人工髋关节置换术(artificial hip replacement,AHR)后假体脱位的原因及处理措施。方法对2000年1月至2010年7月本院和外院收治的17例AHR术后假体脱位患者的术前病因和假体脱位原因进行回顾性分析,并对其进行手法复位和手术治疗。结果术后经4个月～10年随访,17例患者中16例未发生再次脱位,1例于3个月内多次脱位的患者经手术治疗后未再出现脱位。结论假体位置不良、髋关节周围软组织失衡、术者经验不足以及病人因素是假体脱位的常见原因;提高手术水平、采取规范的手术技术、实施术后功能康复和健康教育是预防脱位的重要措施。更多还原

【Abstract】 Objective To explore the causes and management of prosthesis dislocation after artificial hip replacement(AHR). Methods Seventeen patients with prosthesis dislocation after AHR during January 2000 to July 2010 were studied retrospectively through analysis of preoperative causes of disease and reasons of prosthesis dislocation, and were treated by manipulative reduction and the operation. Results After 4 months to 10 years follow up, 16 patients achieved satisfactory results without relapse, 1 patient whose hip joint prosthesis dislocated many times in 3 months walked well without relapse after the second operation. Conclusions Incorrect prosthesis position, unbalanced soft tissue around hip joint, AHR performed by inexperience surgeon and some patient factors are the major causes of prosthesis dislocation after AHR. Important measures to prevent prosthesis dislocation are to improve surgical quality, to carry out the standard techniques, and to put functional rehabilitation and health education into practice. 【更多还原
