【摘要】 目的观察在锁骨下水平切断副神经、移位修复肩胛上神经 ,恢复臂丛损伤患者肩外展功能的临床效果及对斜方肌功能的影响。方法在锁骨下副神经内外侧分支入肌处切断副神经，移位到肩胛上神经 49例 ,术后 2～ 4年随访肩外展功能，其中 20例来院随访的患者又进行了术后斜方肌肌力及电生理检查。结果副神经移位修复肩胛上神经，恢复臂丛损伤患者肩外展功能，其肩外展角度平均 61°，副神经移位后对斜方肌下部功能影响明显，对中、上部无明显影响。结论在锁骨下水平切断副神经、移位修复肩胛上神经后，其肩外展功能恢复良好 ,且对斜方肌上、中部功能无明显影响。更多还原

【Abstract】 Objective To observe the results of restoration of shoulder abduction by spinal accessory nerve transfer which was sectioned infraclavicularly to repair the suprascapular nerve in avulsed brachial plexus injury. Methods The donor nerve of accessory nerve was sectioned at the level of medial and lateral muscular branch entering the trapezius; the proximal segment was used for the transfer to repair the suprascapular nerve. The function of shoulder abduction was followed-up for 2-4 years in 49 patients with avulsed brachial plexus injury, the function of the trapezius after operation was also measured by physical check up and electrophysiological detection in 20 patients. Results The average range of the shoulder abduction was 61° , the muscle strength of the trapezius was unaffected on the upper and middle parts except the lower parts after the operation. Conclusion The shoulder function of the patients with brachial plexus injury recovered satisfactorily after transfer of the accessory nerve sectioned infraclavicularly to repair the suprascapular nerve; the muscle strength of the trapezius was unaffected on its upper and middle portion.更多还原
