RESUMO
【Objective】 To compare the application of modified selective posterior rhiotomy of spinal nerve with traditional rhiotomy in the treatment of spastic cerebral palsy and to evaluate the efficacy and complications of the two surgical methods. 【Methods】 The clinical data of 52 patients with spastic cerebral palsy were analyzed retrospectively. Among them 23 cases were treated with traditional selective posterior rhiotomy and the remaining 29 cases with modified selective posterior rhiotomy. Operation time, amount of blood loss, proportion of root after spinal nerve amputation, postoperative complications, spasm index, ankle clonus, and Holden walking ability at 1 year after operation were compared between the two groups. 【Results】 The operation time of modified selective posterior rhiotomy was longer than that of conventional surgery (P0.05). The proportion of root was smaller in the modified group than in the traditional group (P<0.05). The improved group was superior to the traditional group in the disappearance of ankle clonus (P<0.05). 【Conclusion】 Modified selective posterior rhiotomy has more advantages in eliminating ankle clonus. It is a safe and effective surgical improvement method to evaluate the changes of muscle tension and ankle clonus to quantitatively cut the posterior root of spinal nerve during the operation. This can reduce the proportion of the posterior root of spinal nerve during the operation, and keep the anatomical and functional basis for reducing the occurrence of surgical complications.
