目的探讨对痉挛性脑瘫脊神经后根选择性部分切断术的治疗效果。方法对６例痉挛性脑瘫患者通过临床解剖及采用“神经刺激仪”高选择性脊神经后根部分切断术（ＳＰＲ）。结果术后３～２４个月随访全部病例肌张力降低，步态改善，无感觉障碍等并发症。结论ＳＰＲ是目前治疗痉挛性脑瘫的理想手术，但正确选择手术适应证和脊神经后根切断比例是确保治疗效果的两个重要环节。 Objective To investigate the therapeutic effect of selective partial sectoral rhizotomy on spastic cerebral palsy. Methods Six patients with spastic cerebral palsy were divided into two groups according to the clinical anatomy and the “nerve stimulator” high selective posterior rhizotomy (SPR). Results All the cases were followed up for 3-24 months. Muscle tension was decreased, gait was improved, and no complications such as sensory disturbance were found. Conclusion SPR is the ideal surgery for the treatment of spastic cerebral palsy. However, the correct choice of surgical indications and ratio of posterior rhizotomy is the two important aspects to ensure the therapeutic effect.
