硬脊膜内松解术治疗外伤性陈旧性不全瘫

Intradural lysis for traumatic obsolete incomplete paralysis

目的 探讨外伤性不全瘫的后期治疗。 方法 对 16例外伤性陈旧性不全瘫患者 ,采用显微外科技术切开硬脊膜 ,将蛛网膜、软脊膜、齿状韧带、神经根起始段与脊髓的粘连及周围的纤维条索彻底解除。 结果 16例患者术后随访 2～ 4年 ,均有感觉平面下降 ,肌力增加 1级以上。其中 6例双下肢主要肌群肌力恢复达 3级以上 ,恢复行走能力。

Objective To improve functional recovery of the spinal medulla by relieving the intradural scar and adhesion. Methods Open the dura mater of spinal cord and remove the adhesion and fibre cable between the arachnoid, pia mater spinalis, ligamentum denticulatum, original part of the nerve root and the spinal medulla via microsurgical technique. Results Follow-up of 2 years on average was conducted on 16 patients and showed a fall of sensory plane and an increase of muscle force above 1 grade in all patients. The major muscle force of both lower limbs recovered above 3 grades and the ability of walking regained in 6 patients. Conclusions Release of intradural adhesion by microsurgical method is conducive to reaching a grateful effect for obsolete spinal cord injury.
