我们采用神经移位术，以同侧C7神经根为蒂治疗C5、C6臂丛神经根性撕脱伤。从1998年至2000年，我们对4例C5和C6节前损伤的患者采用这种新技术进行了手术。2例同时行副神经移位至肩胛上神经。随访1 ~ 2.5年，所有病例屈肘肌肌力均恢复至M4（Lovett），2例肩外展> 90 °，外旋30- 40 °，另2例肩外展15- 45 °，无外旋。C7神经支配的肌肉在短期内除肌力下降1级（Lovett）外，无明显损害。这项新技术显示出作为一种有效和安全的治疗C5和C6臂丛神经根性撕脱伤的希望。但当涉及下躯干不完全损伤时，应谨慎使用。(C)2003 Wiley-Liss，Inc.
We applied a nerve transfer, using the ipsilateral C7 nerve root to treat the C5 and C6 root avulsion of the brachial plexus. Four patients with C5 and C6 preganglionic injury were operated on with this new technique from 1998-2000. Transfer of the spinal accessory nerve to the suprascapular nerve was simultaneously done in 2 these patients. After a follow-up of 1-2.5 years, the muscle strength of elbow flexors recovered to M4 (Lovett) in all cases, shoulder abduction of >90degrees with external rotation of 30-40degrees was gained in two cases, and that of 15-45degrees with no external rotation in the other two cases. No remarkable impairment was found in all C7-innervated muscles except for decrease of muscle power of 1 grade (Lovett) in the short run. This new technique shows promise as an efficacious and safe treatment for C5 and C6 root avulsion of the brachial plexus. However, it should be applied prudently when incomplete injuries of the lower trunk are involved. (C) 2003 Wiley-Liss, Inc.
