Abstract
A review of the selective posterior rhizotomy procedure for reduction of spasticity in cerebral palsy is presented. The history of the procedure, selection of patients, operative technique, and results are described. The neurophysiologic basis for spasticity is considered, as well as the role of spasticity in the complex motor disorder of cerebral palsy. Cerebral palsy is a multifaceted disorder of which spasticity is only one aspect. Reduction of spasticity can be effectively achieved using the current technique of selective posterior rhizotomy, but careful patient selection and establishment of realistic goals are vital to successful outcome. Postoperative physical and occupational therapy are felt to be essential for regaining strength and improving motor function following the rhizotomy procedure. Further study in the areas of spasticity, cerebral palsy, and the effects of rhizotomy is expected to advance our treatment of spastic children. ( J Child Neurol 1990;5:179-185).
