摘要
目的:探讨C_8神经根切断治疗上肢脑瘫的效果。方法:锁骨上臂丛探查切口,显露臂丛5个神经根,用肌电仪分别检测5个神经根对指屈肌群及尺侧腕屈肌的收缩幅度,证实C_8为最高幅度后切断之。结果:C_8神经根切断后,对上肢及手部功能无影响,能减轻屈腕及屈指肌张力。结论:C_8神经根切断后短期内能减轻屈腕及屈指肌张力,长期效果有待于进一步随访及观察。
To investigate the clinical result of C_8 nerve root resection for treatment of cerebral palsy spasticity in the upper extremities. Methods: The five nerve roots of brachial plexus were exposed and identified in a supraclavicular approach. Intraoperative electromyography was carried out to stimulate C_5～T_1 nerve roots successively and record EMAP of flexor carpi ulnaris and flexor digitorum profundus. C_8 nerve root was cut when it was confirmed that EMAP with highest amplitude was recorded after stimulation of C_8. Results: Muscle tension of the flexors of the wrist and fingers was remarkablely reduced after C_8 nerve root resection. The function of the upper extremity and hand was not jeopardised. Conclusion: C_8 nerve root resection can release spasticity of the flexors of the wrist and fingers in a short period after the operation. Its long term effect is subject to further observation and follow up.
