摘要
在50例成人上肢标本上,解剖观测了桡神经肱三头肌支的数目和纤维数,并用 AChE 组化法对桡神经肱三头肌支及尺神经进行了功能定位。肱三头肌每个头均有3(2～5)支分布。长头肌支平均横径0.8±0.1mm,可分离长度24.9±0.5mm,纤维数345±40根,均为运动神经;内侧头肌支平均横径0.9±0.1mm,可分离长度68.9±0.7mm。纤维数400±35根,第三支为混合性,其余为运动神经;外侧头肌支平均横径0.9±0.1mm,可分离长度48.5±0.6mm。纤维数353±38根,第三支为混合性,其它均为运动神经。根据观测结果可设计以桡神经肱三头肌支转位修复臂丛下干根性撕脱伤和尺神经干的新术式。
On 50 adult upper limb specimens,the brachial triceps branches of radial nerve were studiedby dissection and AChE histochemical method.There are averagely 3(2～5)nerve branches toeach head of the brachial triceps muscle.The nerve branches to the long,the medial and the later-al heads of triceps brachii are respectively 0.8±0.1mm,0.9±0.1mm and 0.9±0.1mm in diame-ter;24.9±0.5mm,68.9±0.7mm and 48.5±0.6mm in separable length;and 345±40,400±35and 353±38 in fiber number.All the nerve branches are composed of motor nerve fibers exceptthe third branches to the medial and lateral heads,which are composed of both motor and sensoryfibers.A new operation method was designed for repairing ruptures of ulnar nerve or the inferiortrunk of brachial plexus by transferring the brachial triceps branches of radial nerve.
