目的 总结髋关节置换术术后假体周围感染的临床特点及治疗效果.方法 对25例髋关节置换术后假体周围感染的老年患者术中取组织行病原学培养,根据假体周围感染的不同分期,采用清创灌洗、一期或二期关节翻修、敏感抗生素使用等方法治疗.结果 患者均获得随访,时间6~60个月.25例中22例细菌培养结果为阳性,21例为单一菌感染,1例为大肠埃希菌和奇异变形菌混合感染.23例临床治愈,2例死亡.20例翻修术后6个月Harris评分:优8例,良7例,中4例,差1例.患者总满意率为15/20.结论 确定假体周围感染的病原菌非常重要.适当的外科治疗和抗生素治疗可以达到良好的临床效果,预防感染更为重要.%Objective To summarize the clinical features and treatment effect of postoperative periprosthetic hip in-fections.Methods Twenty-five cases of elderly patients with periprosthetic infection after hip replacement underwent tissue pathogenic culture.According to the different stages of periprosthetic infection,debridement,lavage,one-stage or two-stage revision,and sensitive antibiotic were used in the treatment.Results All patients were followed up for 6~60 months. Among 25 cases,22 cases were positive for bacterial culture,21 cases were single bacteria infection, 1 case was mixed infection of escherichia coli and proteus mirabilis. The 23 cases were cured and 2 cases were died. According to Harris score standard after 6 months of revision,8 cases were excellent,7 good,4 fair,1 poor. The to-tal satisfaction rate of patients was 15/20.Conclusions It is very important to determine the periprosthetic infection pathogens. Appropriate surgical treatment and antibiotic therapy can achieve good clinical results. Prevention of in-fection is more important.
