  • Title: Selective functional posterior rhizotomy for treatment of spastic cerebral palsy in children. Review of 50 consecutive cases.
    Author: Steinbok P, Reiner A, Beauchamp RD, Cochrane DD, Keyes R.
    Journal: Pediatr Neurosurg; 1992; 18(1):34-42. PubMed ID: 1419840.
    Abstract:
    Fifty consecutive children are described with spastic cerebral palsy treated with selective functional lumbar and sacral rhizotomy and followed for a minimum of 6 months. In all patients, spasticity improved postoperatively, but this was not necessarily accompanied by a functional improvement. Eighteen children who could not walk preoperatively were able to do so after rhizotomy. All 17 children who could walk preoperatively could do so following surgery, and in 15, gait was improved. Complications included transient urinary dysfunction in 4 children and sensory loss in 1. The operative procedure evolved with time: the technique of replacement laminotomy was refined; the electrophysiologic basis for selection of nerve rootlets changed after studies of nonspastic controls; smaller percentages of the L3 and L4 roots were sectioned in an attempt to prevent postoperative weakness of quadriceps, and there was a trend in the most recent patients to cut a smaller portion of all the posterior roots.
