We describe 2 patients with nonunion of the clavicle and dynamic compression of the subclavian artery. In both patients, no structural abnormality of the subclavian vessels was evident at rest; however, with the arm in hyperabduction, arterial occlusion occurred because of the mobility of the fracture and a prominent callus.
This small case series demonstrates an important and, to our knowledge, unreported clinical complication of clavicle fracture nonunion. We believe that this complication is worth considering as a rare but important cause of pain in patients with delayed union or nonunion of the clavicle.
我们描述了2例锁骨骨不连合并锁骨下动脉动态受压的患者。在这2例患者中，静息时锁骨下血管均无明显结构异常；然而，当手臂过度外展时，由于骨折部位的活动度及明显的骨痂，导致动脉闭塞。
这个小病例系列展示了一种重要的、据我们所知尚未报道过的锁骨骨折不愈合的临床并发症。我们认为，这种并发症值得被视为锁骨延迟愈合或不愈合患者疼痛的一个罕见但重要的原因。
