【摘要】 目的:探讨C₈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C₈为最高幅度后切断之。结果:C₈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:C₈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。更多还原

【Abstract】 To investigate the clinical result of C₈ 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 C₅～T₁ nerve roots successively and record EMAP of flexor carpi ulnaris and flexor digitorum profundus. C₈ nerve root was cut when it was confirmed that EMAP with highest amplitude was recorded after stimulation of C₈. Results: Muscle tension of the flexors of the wrist and fingers was remarkablely reduced after C₈ nerve root resection. The function of the upper extremity and hand was not jeopardised. Conclusion: C₈ 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.更多还原
