正中神经前臂段浅层肌支的应用解剖

目的测量正中神经前臂段浅层肌支的解剖学数据,为正中神经的创伤修复提供形态学依据。方法采用解剖剥离测量方法,对30侧10%甲醛固定的成人上肢标本正中神经发出的前臂段浅层肌支进行解剖学观察。结果正中神经前臂段浅层肌支的分支类型有1支型、2支型、3支型和4支型。其中,旋前圆肌支以3支型(87%),指浅屈肌支(90%)以4支型,桡侧腕屈肌支(96.7%)和掌长肌支(96.7%)以1支型出现率最多。正中神经前臂段浅层肌支主要集中于前臂的4%～65%。结论确定了正中神经前臂段浅层肌支在前臂的危险区间;讨论了有利于开展带神经血管蒂肌瓣移植的肌支类型。

Applied anatomy of median nerve and its superficial muscular branches in forearm

Objective To measure the anatomical data of the superficial muscular branches of the median nerve in the forearm and provide the morphological evidence for the repair of the damaged median nerve in the forearm.Methods By the method of the anatomical dissection, the superficial muscular branches of the median nerves from 30 upper extremities of adult cadavers were measured and observed anatomically.Results There are four types of the superficial muscular branches of the median nerve in the forearm, including...
