Surgical treatment of spasticity in cerebral palsy

Abstract

Since 1971, we have surgically treated spasticity in 109 cases of cerebral palsy with posterior rhizotomy. The best results have been obtained with functional posterior rhizotomy, an original modification of Foerster's technique, in which the selection of the roots/rootlets to be sectioned is based on functional exploration of the spinal circuits involved in the maintenance of spasticity, using intraoperative electrostimulation on dorsal roots. This method makes selective sections possible, thereby saving a larger number of normal proprioceptive afferents, with consequent reduction in negative side effects. No recurrencies have been observed in our 3-year follow-up. The main indication is Little's disease.
