A 62-year-old man presented with a nonunion of the humerus shaft. Using a standard triceps splitting approach, a longitudinal incision along the posterior aspect of the arm was created. Three independent radial nerves coursed posteriorly and inferolaterally around the humerus were identified in spiral groove. Three nerves resembled in the size, color, and course in the operative field. Although the prevalence of the anomaly is probably quite low, the possibility of identification of this anomalous condition of radial nerve should be kept in mind when performing posterior approach on the humerus.
一名62岁男性因肱骨干骨不连前来就诊。采用标准的肱三头肌劈开入路，沿手臂后侧做一纵向切口。在螺旋沟内发现三条独立的桡神经，它们沿肱骨后方向下外侧走行。在手术视野中，三条神经在大小、颜色和走行上相似。尽管这种异常情况的发生率可能相当低，但在对肱骨进行后侧入路手术时，应牢记识别这种桡神经异常情况的可能性。
