【摘要】： 我们设计了以远端腕横纹为横坐标,3、4掌骨间隙的纵行线为纵坐标的手掌部二分法。通过19侧新鲜标本的显微解剖学研究,应用该方法分别观测了正中神经、尺神经及其分支在该坐标系内的体表投影位置。通过本组研究证明:1手掌两分区法具有简明实用的特点,依据神经分支点体表投影的位置,可以准确地判断正中神经、尺神经及其分支在手部的走行及分布;2手掌部正中神经、尺神经及其分支的位置相对恒定,但仍存在一定的变异;3依据对神经分支点的测量结果,可设计腕管综合症、腕尺管综合症、正中神经返支探查与尺神经深支探查手术的合理切口。
[Abstract]:We designed a method of palmar division with the vertical line of the space between the distal carpal striae and the metacarpal space as the vertical coordinate and the transverse striation of the distal wrist as the transverse coordinate of the metacarpal space. Based on the microanatomical study of 19 fresh specimens, the projection positions of median nerve, ulnar nerve and their branches in this coordinate system were observed by this method. It is proved by this study that the two-partition method of "1: 1 palm" is simple and practical. According to the position of the surface projection of the nerve branch point, the median nerve, the ulnar nerve and its branches can be accurately judged and distributed in the middle nerve of the palm. The position of ulnar nerve and its branches is relatively constant, but there are still some variations. According to the measured results of nerve branches, carpal tunnel syndrome and ulnar tunnel syndrome can be designed. Rational incision for exploration of recurrent branch of median nerve and deep branch of ulnar nerve.
