Compression neuropathy of a single digital nerve is a rare entity. We report the case of a patient with numbness in the distribution of the radial digital nerve of the thumb caused by the use of a walking stick. The nerve was compressed between the handle of the stick, the loop and the radial sesamoid bone of the first metacarpophalangeal joint. The site of the lesion was confirmed by electrophysiologic examination. Orthodromic recording of the sensory response from the radial palmar digital nerve of the thumb documented a complete absence of nerve action potential whereas the ulnar digital thumb nerve showed a normal response. Sensory function was restored when a padded ski glove was used to protect the area of the metacarpophalangeal joint whilst using the stick.
单一指神经的压迫性神经病变是一种罕见的情况。我们报告了一例因使用手杖导致拇指桡侧指神经分布区域麻木的患者。神经在手杖手柄、环带与第一掌指关节的桡侧籽骨之间受到压迫。病变部位通过电生理检查得以证实。对拇指桡侧掌侧指神经的感觉反应进行顺向记录显示完全没有神经动作电位，而拇指尺侧指神经显示正常反应。在使用手杖时，使用有衬垫的滑雪手套保护掌指关节区域后，感觉功能得以恢复。
