The incidence of pseudotumor formation has been reported to be 1% in patients with metal-on-metal resurfacing arthroplasties. This complication is not exclusive to these patients. We report a case of pseudotumor formation secondary to femoral head-neck corrosion after a metal-on-polyethylene uncemented total hip arthroplasty.
金属对金属表面置换关节成形术患者的假瘤形成发生率据报道为 1%。这种并发症并非这些患者所特有。我们报告了一例金属对聚乙烯非骨水泥全髋关节置换术后因股骨头颈腐蚀引起的假瘤形成。
