Orthodromic conduction of the radial nerve digital branches to the third digit from the anatomic snuffbox has rarely been described. This paper describes a technique for measuring conduction of the lateral and medial digital branches of the radial nerve to the third digit at a distance of 10cm from the base of the digit to the anatomic snuffbox. An evoked response from the lateral digital branch was recorded in each of the 56 nerves tested. Responses had an average latency of 2.10 +/- .18msec. Responses from the medial digital branches of the nerve were obtained in only 55% of the 49 nerves tested. Responses had an average latency of 2.11 +/- .21msec. When no appreciable response was recorded at the anatomic snuffbox from the medial digital branch, a response was recorded from the ulnar nerve at the volar wrist at 14cm.
从解剖学鼻烟壶至第三指的桡神经指支的顺向传导鲜有描述。本文描述了一种测量桡神经外侧和内侧指支在距指尖基部10厘米至解剖学鼻烟壶处向第三指传导的技术。在所测试的56条神经中，每条均记录到了来自外侧指支的诱发反应。反应的平均潜伏期为2.10±0.18毫秒。在所测试的49条神经中，仅55%记录到了来自神经内侧指支的反应。反应的平均潜伏期为2.11±0.21毫秒。当在内侧指支的解剖学鼻烟壶处未记录到明显反应时，在掌侧腕部距尺神经14厘米处记录到了反应。
