This study was undertaken to determine the frequency of variations involving the anatomy of Guyon's canal. A series of 58 wrist dissections revealed a 22.4% incidence of anomalous muscles and a 1.7% incidence of anomalous nerve paths. The relationship of the deep branch of the ulnar artery to the superficial and deep branches of the ulnar nerve was found to vary. Accessory muscles passing through Guyon's canal are common, and are often found bilaterally. Aberrant branching of the ulnar nerve in this area is rare.
本研究旨在确定Guyon管解剖结构变异的发生率。一系列58例腕部解剖显示，异常肌肉的发生率为22.4%，异常神经路径的发生率为1.7%。发现尺动脉深支与尺神经浅支和深支的关系存在差异。穿过Guyon管的副肌很常见，且常双侧出现。该区域尺神经的异常分支很少见。
