Hyperselective posterior rhizotomy in treatment of spasticity of paralytic limbs

One hundred and eight patients with spasticity of the paralytic limbs were treated successfully with hyperselective posterior rhizotomy (SPR). Of the 108 patients, 100 had cerebral palsy, 2 hemiplegia, 3 sequelae of cerebral injury, 2 paraplegia and 1 multiple sclerosis. Twelve patients received cervical SPR and 96 lumbosacral SPR. Laminectomy is performed to open the dura and to separate the posterior spinal root into several rootlets. The lower threshold rootlets were divided after electrical stimulation. Follow-up for 6 to 30 months showed that the effective rate of reducing spasticity was over 95% and functional improvement rate over 80%.
