A case of bone necrosis with a pseudotumor following metal-on-metal total hip arthroplasty is presented. The patient showed no abnormal magnetic resonance findings 2 years postoperatively, but serum metal ion levels were elevated. The patient developed hip pain 3.5 years postoperatively, and bone necrosis with a pseudotumor was found. The present patient emphasized the fact that tissue necrosis associated with failed metal-on-metal bearing hip might not be limited to soft tissues, but bone necrosis could occur.
本文报告一例金属对金属全髋关节置换术后发生骨坏死并伴有假瘤的病例。患者术后2年磁共振成像未发现异常,但血清金属离子水平升高。患者术后3.5年出现髋关节疼痛,发现骨坏死并伴有假瘤。该患者强调了这样一个事实,即金属对金属承重髋关节失败相关的组织坏死可能不仅限于软组织,骨坏死也可能发生。
