全臂丛根性损伤，因为动力纤维不足和神经再生距离太远，使患肢屈腕屈指功能

Root injury of the whole brachial plexus, due to insufficient power fibers and too long nerve regeneration distance, makes the recovery of the flexion and flexion function of the affected limb unsatisfactory. Repairing the inferior trunk of the contralateral neck 7 directly provides a new idea for the repair of brachial plexus injury. It not only shortens the regeneration distance of the nerve, reduces a nerve suture opening, but also makes the ulnar nerve and the median nerve innervate. The flexor muscle groups have been restored, and the effect of the recovery of wrist flexion and flexion function has been improved.

Full-arm plexus root damage, because the lack of power fibers and nerve regeneration distance is too far, so that the resusperation of the limb's condescensive function is not ideal. The direct repair of the healthy side neck 7 to the lower dry, for the repair of nerve damage in the arm plexus provides a new way of thinking, it not only shortens the regeneration distance of the nerve, reduces a nerve succumberation mouth, but also makes the ruler nerve and the flexo group dominated by the nerve in the middle have been restored, improving the efficacy of the reflexive function recovery.

Because of the lack of dynamic fibers and the long distance of nerve regeneration, the recovery of wrist and finger flexion is not ideal. It not only shortens the nerve regeneration distance, reduces a nerve suture, but also recovers the flexor muscles innervated by ulnar nerve and median nerve, and improves the recovery of wrist and finger flexion function.
