Despite improved strategies to prevent prosthetic joint infection, as the total number of joint replacements increases, so does the absolute number of infections. Radiography serves as the first-line imaging modality for the assessment of a suspected prosthetic joint infection. Additionally, serial radiographs acquired after a surgery to eradicate a prosthetic joint infection are an important clinical tool. Prosthetic joint infections are often treated with a 2-stage replacement arthroplasty utilizing a prosthesis with antibiotic-loaded acrylic cement. While complications are uncommon with this procedure, imaging may demonstrate periprosthetic fractures, as well as spacer migration, joint dislocation, and spacer fracture. We describe the classification of prosthetic joint infections, the clinical and imaging diagnosis, and treatment strategies. Familiarity with the hardware utilized in the management of the prosthetic joint infection, and its potential complications is fundamental to accurate imaging interpretation.

人工关节感染:两阶段置换术的诊断,处理和并发症。

尽管有改进的预防假体关节感染的策略,但随着关节置换总数的增加,感染的绝对数量也增加了。放射线照相作为评估疑似假体关节感染的一线成像手段。另外,在手术中根除人工关节感染后获得的系列放射线照片是重要的临床工具。假体关节感染通常使用两阶段置换关节置换术进行治疗,该假体采用装有抗生素的丙烯酸水泥进行假体修复。尽管此手术并发症很少见,但影像学检查可显示假体周围骨折,以及垫片移位,关节脱位和垫片骨折。我们描述了人工关节感染的分类,临床和影像学诊断以及治疗策略。
