人工髋关节置换术后感染的Ⅱ期翻修手术治疗

目的:探讨Ⅱ期翻修手术治疗在全髋关节置换术后感染的疗效和临床体会,以及该技术的安全性和有效性。方法:2006年1月至2009年3月,采用Ⅱ期翻修手术治疗17例(17髋)髋关节疾患,男7例,女10例;年龄43～75岁,平均58.5岁。17例患髋均有不同程度疼痛;关节液或假体周围组织细菌培养,11例阳性,6例阴性;术中所有患者假体周围组织病理检查发现急性炎症;8例出现与假体相通的窦道;15例血沉增快,15例C反应蛋白增高;17例X线片有骨融解、假体松动及骨膜反应等表现。所有病例采用Ⅱ期翻修手术治疗,Ⅰ期手术彻底清创,取出假体,以含万古霉素的骨水泥假体临时旷置,术后静脉输入抗生素4周后,改为口服抗生素6周。术后定期复查血沉和C反应蛋白,待结果正常后再Ⅱ期行人工髋关节翻修术。结合手术前后患者髋关节Harris评分,对人工髋关节置换术后感染的Ⅱ期翻修手术治疗进行分析。结果:所有患者获随访,时间12～35个月,平均19.5个月,术后X线片显示关节假体位置正确。Harris髋关节评分从术前平均(39.3±5.6)分提高到末次随访的平均(84.4±10.3)分(t=15.86,P0.01)。结论:Ⅱ期翻修手术治疗人工髋关节置换术后感染,具有疗效良好、安全可靠等优点,其为人工髋关节置换术后感染的治疗提供一种可靠的选择。

Clinical study on second-stage revision in the postoperative infection after total hip replacement

Objective:To study the therapeutic effects and clinical experiences of second stage revision in postoperative infection after total hip replacement and to explore its security and validity. Methods:From January 2006 to March 2009,17 hips in 17 patients(7 males and 10 females,ranging in age from 43 to 75 years,with an average of 58.5 years) were treated with second stage revision. All the patients suffered from different degrees of hip pain. In bacilliculture of Synovial fluid or periton- sillar tissue,11 pa...
