A 31-year-old man without any other medical history developed severe hip pain seven years after right primary total hip arthroplasty (THA). Radiography revealed extensive progressive osteolysis around the cup and stem. Periprosthetic infections and adverse reactions to the metal debris were absent. Right revision THA was performed, and chronic expanding hematoma (CEH) was diagnosed based on a comprehensive assessment. CEH should be diagnosed early because progressive osteolysis may generate an extensive hematoma. Thus, it should be considered when progressive osteolysis of an unknown cause is encountered after THA.
一名31岁无其他病史的男性在初次右全髋关节置换术（THA）七年后出现严重的髋关节疼痛。X线检查显示髋臼杯和股骨柄周围有广泛的进行性骨质溶解。不存在假体周围感染和对金属碎屑的不良反应。进行了右髋关节翻修术，并通过综合评估诊断为慢性扩张性血肿（CEH）。应早期诊断CEH，因为进行性骨质溶解可能会产生广泛的血肿。因此，在THA后遇到原因不明的进行性骨质溶解时应考虑到这一点。
