Pathological fracture is a rare but serious complication of radiotherapy. We report on a 44-year-old man who presented with a subtrochanteric femoral fracture 15 years after radiotherapy for a soft-tissue sarcoma in the thigh. We discuss its potential causes, a scoring system to identify high-risk patients for prophylactic intramedullary nailing of the femur, and radiographic signs to identify an impending insufficiency fracture.
病理性骨折是放疗罕见但严重的并发症。我们报告一名44岁男性，他在因大腿软组织肉瘤接受放疗15年后出现股骨转子下骨折。我们讨论了其潜在病因、用于识别股骨预防性髓内钉固定高危患者的评分系统以及用于识别即将发生的骨质疏松性骨折的影像学征象。
