A 50-year-old man developed a pelvic mass following uncemented total hip arthroplasty. The mass communicated with the hip via an acetabular defect after loosening of the acetabular component. Operative and histologic findings revealed a foreign body reaction to polyethylene debris. Revision arthroplasty and excision of the pelvic mass were performed successfully through a single incision. A mass adjacent to a loose prosthesis may present as polyethylene failure following total hip arthroplasty. Revision arthroplasty and excision of the mass after an accurate diagnosis are recommended.
一名50岁男性在非骨水泥型全髋关节置换术后出现盆腔肿物。髋臼假体松动后，该肿物经髋臼缺损与髋关节相通。手术及组织学检查结果显示对聚乙烯碎屑有异物反应。通过单一切口成功进行了翻修关节成形术及盆腔肿物切除术。全髋关节置换术后，假体周围的肿物可能提示聚乙烯磨损。建议在明确诊断后进行翻修关节成形术及肿物切除术。
