目的:总结11例脑瘫病人采用选择性脊神经后根切断术的治疗方法和效果。方法:采用显微手术显露:L_2～S_1脊神经根。应用隔离电刺激仪来确定需切断的脊神经根,光学显微镜观察病理变化。结果:11例病人术后均取得良好疗效,痉挛解除,肌张力降低,步态改善,对感觉功能影响小。9例病人经2年以上随访疗效明显,2例病人失访。结论:选择性脊神经后根切断术治疗痉挛性脑瘫疗效较好,其优点具有解除肢体痉挛,不影响运动和感觉功能,疗效确切:

In this paper 11 cases of cerebral palsy treated by selective posterior rhizotomy was reported.
