Abstract

We describe a variation of selective dorsal rhizotomy for spastic cerebral palsy that involves sectioning of the dorsal spinal roots immediately caudal to the conus medullaris. The operation entails an L1-L2 laminectomy, ultrasonographic localization of the conus medullaris, and partial deafferentation of the L1-S2 roots with electromyographic testing under an operating microscope. In 66 children with cerebral palsy, the operation reduced spasticity in the lower extremity without complications, e.g., motor weakness, neurogenic bladder, and sensory loss. It offers several important advantages over alternative techniques.
