在手术显微镜下解剖50例成人上肢。多数(68％)桡神经浅支在内上髁平面之下约16mm处由桡神经分出。浅支干长约180mm,以被肱桡肌遮盖与否分为浅、深两段。两段交界处相当于前臂上2/3与下1/3的分界平面。浅支从上而下逐渐变宽,其横断面近侧段近似圆形,远侧段为椭圆形。分布于桡神经浅支的动脉主要来自桡动脉的外侧皮支和肌支。浅支的浅、深两段各有1～4支动脉分布,测量了这些动脉支的起始位置。前臂外侧皮神经在前臂分为两支,并发支与桡神经浅支交通。供应神经的动脉有2～8支,多来自桡动脉的外侧皮支。在桡动脉浅、深段交界的外侧约5～6mm处,易于找到前臂外侧皮神经。讨论了带血管蒂神经移植的局部解剖问题。
Fifty adult adults were dissected under a surgical microscope. The majority (68%) of the radial nerve superficial branches are separated by the radial nerve at about 16 mm below the medial epicondyle plane. Shallow dry length of about 180mm, to be covered by the brachioradialis muscle is divided into shallow, deep two. The junction of the two sections is equivalent to the demarcation plane of 2/3 and 1/3 of the forearm. Superficial branch widens gradually from top to bottom, the proximal section of the cross section is approximately circular, and the distal section is oval. The arteries distributed in the superficial branch of the radial nerve mainly come from the lateral branches and branches of the radial artery. Superficial branches of shallow and deep two have 1 ~ 4 artery distribution, measuring the beginning of these branches of arteries. Forearm lateral cutaneous nerve in the forearm is divided into two, with branch and radial nerve superficial traffic. Nerve supply artery 2 to 8, mostly from the radial artery of the lateral branch. In the radial artery, deep junction of the outer side of about 5 ~ 6mm, easy to find the lateral forearm nerve. Discussed the local anatomical issues with vascular pedicled nerve grafts.
