[Hyperselective posterior rhizotomy in the treatment of spasticity of paralytic limbs].

108 cases of spasticity of paralytic limbs were treated successfully with hyperselective posterior rhizotomy (SPR). Among them, 100 had cerebral palsy, 2 hemiplegia, 2 paraplegia, 3 sequelae of cerebral injury, and 1 multiple sclerosis. Cervical SPR was performed in 12 cases and lumbosacral SPR in 96 cases. After laminectomy, the posterior nerve roots were split into some rootlets, and the lower threshold rootlets were divided after electrical stimulation. Follow up for 6-30 months showed an effective rate of 95% and an improvement rate of 81%.
