The relationship between prosthetic hip infection and a psoas abscess is poorly documented. We determined the frequency of prosthetic hip infections associated with psoas abscesses and identified their determinants.
We conducted a 2-year observational study. Data from patients with psoas abscesses that were associated with prosthetic hip infections were examined in a case-control study.
Of 106 patients admitted to the Infectious Diseases Department with prosthetic hip infection, 13 also had a psoas abscess (12%; 95% CI: 6-19). By conditional logistic regression analysis, psoas abscesses were observed more frequently in cases of hematogenous prosthetic infections (OR = 93, p = 0.06) and in patients with a history of neoplasm (OR = 20, p = 0.03).
Our results suggest that the presence of psoas abscesses is a frequent but under-diagnosed complication of prosthetic hip infection. We recommend that an abdominal CT scan be performed on patients with hematogenous prosthetic hip infection or with a history of neoplasm.
人工髋关节感染与腰大肌脓肿之间的关系鲜有文献记载。我们确定了与腰大肌脓肿相关的人工髋关节感染的发生率，并找出了其决定因素。
我们进行了一项为期2年的观察性研究。在一项病例对照研究中，对与人工髋关节感染相关的腰大肌脓肿患者的数据进行了检查。
在因人工髋关节感染入住传染病科的106例患者中，13例同时患有腰大肌脓肿（12%；95%置信区间：6%-19%）。通过条件逻辑回归分析，血源性人工感染病例（比值比=93，p=0.06）和有肿瘤病史的患者（比值比=20，p=0.03）中腰大肌脓肿的发生率更高。
我们的结果表明，腰大肌脓肿是人工髋关节感染常见但诊断不足的并发症。我们建议对血源性人工髋关节感染患者或有肿瘤病史的患者进行腹部CT扫描。
