Abstract：
METHODS: A 54-year-old male with osteoarthritis of the right long finger metacarpophalangeal joint underwent PyroCarbon joint arthroplasty. Seven years later the patient presented for metacarpophalangeal joint swelling and pain. The workup was benign, without signs of implant complication or osseous abnormality. He underwent washout and two-stage revision, where gross implant wear and debris not demonstrated by radiograph were found. He then returned to the operating room for reimplantation of a PyroCarbon implant.
CONCLUSIONS: This case demonstrates a novel presentation of aseptic PyroCarbon implant failure in the hand without radiographic abnormality that can alter operative management by reducing operating room returns.

摘要：
方法：一名54岁男性右长指掌指关节骨性关节炎行Pyrocarbon关节置换术。七年后，患者出现掌指关节肿胀和疼痛。检查是良性的，没有植入物并发症或骨异常的迹象。他接受了冲洗和两阶段的修正，在X线照片未显示的植入物的磨损和碎片被发现。然后，他回到手术室重新植入PyroCarbon植入物。
结论：此病例显示了手部无菌PyroCarbon植入物失败的新表现，没有影像学异常，可以通过减少手术室返回来改变手术管理。
