在上肢周围神经中,桡神经最易遭受外伤。其损伤多数是肱骨干骨折所引起。此外,上肢置于外展位的手术、桡骨颈骨折、大量骨痂生成以及枪弹伤、切割伤均可引起桡神经的损伤。桡神经主要功能是伸肘、伸腕和伸指。由于桡神经损伤部位高低不同,临床表现也不一样:(1)腋部(肱三头肌支发出之上)桡神经损伤。上肢所有伸肌
In the upper extremity peripheral nerves, the radial nerve is the most vulnerable to trauma. Most of the damage caused by humeral shaft fractures. In addition, the upper extremity surgery placed in the abduction, radial neck fracture, a large number of callus formation and bullet wounds, cutting injuries can cause radial nerve injury. Radial nerve main function is to extend the elbow, extensor and extensor. Due to the different parts of the radial nerve injury, clinical manifestations are not the same: (1) axillary (triceps branch above) radial nerve injury. Upper extremity all extensors
