Stretch injuries of the infraclavicular brachial plexus have a much better prognosis for spontaneous recovery than do their supraclavicular counterparts. We present three patients with stretch injuries of the infraclavicular brachial plexus who had spontaneous restoration of function in all muscles except the deltoid. Decreased shoulder abduction was a serious handicap to these individuals. At surgical exploration, each patient had an isolated, complete axillary nerve disruption at the quadrilateral space. Deltoid muscle function was restored in all three patients by repair of the axillary nerve with sural nerve grafts across the quadrilateral space.
锁骨下臂丛神经牵拉伤的自然恢复预后比锁骨上臂丛神经牵拉伤好得多。我们报告了3例锁骨下臂丛神经牵拉伤患者，除三角肌外，所有肌肉的功能均自发恢复。肩部外展受限对这些患者来说是一个严重的障碍。手术探查时，每位患者在四边孔处均有孤立的、完全性腋神经断裂。通过用腓肠神经移植跨过四边孔修复腋神经，3例患者的三角肌功能均得以恢复。
