目的探讨腰骶段限制性椎板切除显露选择性脊神经后根切断术 (SPR)治疗脑性瘫痪下肢痉挛。方法选择肌张力在Ⅲ级（ Ashworth评定标准）以上的中重度痉挛性脑性瘫痪患儿 12例，限制性切除L2下半部、 L3及L5棘突和椎板，显露并分段切开硬脊膜，将 L2～ S1脊神经后根分开并分束，选择阈值低的神经束按一定比例切断。结果随访 1～ 3年，下肢肌张力均下降 2～ 3级，腰椎未见畸形改变。结论该术式减少了手术对脊柱稳定性的影响和防止术后并发症。
： Objective To confirm the efficiency of selective posterior rhizotomy combined with restrictive laminectomy in treating lower limbs’ spasm of cerebral palsy.Methods It was choosed for 12 cases of moderate and severe spastic cerebral palsy, their muscle tension were overⅢ (Ashworth’s), and their age were from 5 to 12 years.Underwent restrictive laminectomy on the lower part of L2、 L3、 L5 vertebral laminals, incited the dura mater spinalis , then seperated the posterior roots of L2～ S1 spinal nerves into several branches and performed rhizotomy on some branches of lower threshold according to certain ratio.Results The follow－up was 12 cases period from 1 to 3 years. The tones of muscle were reduced 2 or 3 scales, myospasticities were alleviated effectively and no spinal column deformity occured. Conclusion The restrictive laminectomy enhanced the stability of verberal column and prevented complications of postlaminectomy syndrome.
