A 9-year-old boy with a widely displaced Type-III supracondylar humerus fracture presented with a painful mass at the antecubital fossa after pin fixation. Exploration of the mass caused bleeding from a brachial artery pseudoaneurysm that necessitated repair with a saphenous vein graft. Six weeks later, the fracture had healed without complications.
We describe an unusual presentation of a pediatric supracondylar humerus fracture that highlights the importance of including vascular injury in the differential diagnosis for similar presentations.
9 岁男孩，肱骨干骺端骨折（Type-III 型），经克氏针固定后在前臂出现疼痛性肿块。探查该肿块时，发现肱动脉假性动脉瘤出血，需要用隐静脉移植物修复。6 周后，骨折愈合，无并发症。
我们描述了一种儿童肱骨髁上骨折的不常见表现，强调了在类似表现的鉴别诊断中包括血管损伤的重要性。
