对30具新鲜尸体60侧腕部标本进行了正中神经在腕管内的走行及分支变异的研究。结果与文献进行了比较。研究证实韧带外型运动分支变异最常见。神经的经韧带走行特别重要：它通常伴有肥大的肌肉，并且在切断支持带时，隐藏在该肌肉内的神经很容易被切断。结果证实了腕管开放时从尺侧入路正中神经的必要性。
A study of the variations of the course and branching pattern of the median nerve within the carpal tunnel were carried out on 60 wrists from 30 fresh cadavers autopsied in the Department of Forensic Medicine of Jagiellonian University Medical College. The results were compared with the literature. The study confirmed that the extraligamentous type of motor branch variation is most common. The transligamentous course of the nerve is of special importance: it is usually accompanied by hypertrophic muscle, and the nerve hidden within this muscle can easily be cut during transection of the retinaculum. The results proved the necessity of approaching the median nerve from the ulnar side when opening the carpal tunnel.
