脊髓圆锥部选择性脊神经前、后根切断术治疗痉挛性脑瘫

探讨脊髓圆锥部选择性脊神经前，后根切断术治疗痉挛性脑瘫的疗效。方法１９９４－１９９８年在脊髓圆锥部进行选择性脊神经后根切断术的同时进行选择脊神经切断术治疗痉挛性脑瘫２８例。并选１０例双下肢痉挛性脑瘫患者作同体两侧肢体不同方法治疗对照，右侧行ＳＰＲ＋ＳＡＲ手术，左侧仅行ＳＰＲ手术。结果脊髓圆锥部手术较腰骶部传统术式具有切口小，创伤小，出血少，操作简捷，手术时间短和并发症少等优点。按刘小林疗效评价标准

Selective Posterior and Anterior Rhizotomy at the Level of Conus Medullaris for Treatment of SpasticCerebral Palsy

Objective To describle selective posterior rhizotomy ( SPR) combined with selective an-terior rhizotomy (SAR) at the level of conus medullaris for the treatment of spastic cerebral palsy, and to observeits effects. Methods Twenty-eight patients with spastic cerebral palsy were treated with SPR and SAR at thelevel of conus medullaris. 10 cases of bilateral spastic paralysis were used as self control studies. They hadSPR and SAR on the right side and only SPR on the left side. Results The new technique simplified theoperative procedure, maintained the maximal stability of the spinal column, and gave a lower rate of compli-cations. According to the LIU Xiaolin's standard of evaluation, the spasmolytic effect of the SPR combined withSAR excelled that of SPR alone. Conclusion The modified procedure at the level of conus medullaris is safe,and SAR has a good clinical value as a replenishment.
