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 sequel ae of cerebral injury, 2 paraplegia and 1 multiple sclerosis. Twelve p atients received cervical SPR and 96 lumbosacral SPR. Laminectomy is p erformed to open the dura and to separate the posterior spinal root in to several rootlets. The lower threshold rootlets were divided after e lectrical stimulation. Follow-up for 6 to 30 months showed that the ef fective rate of reducing spasticity was over 95% and functional improv ement rate over 80%.
