Abstract
On close examination of the available data, we conclude that convincing evidence of the efficacy of dorsal rhizotomy for improving motor function in cerebral palsy has yet to be shown, in spite of the fact that the operation has been used, with some variations in technique, for over 80 years. It is a procedure that is demanding of patient, family, and a large professional staff. While it does not entail a large operative risk, it must be uncomfortable during the acute and immediate recovery phases. Long-term complications and disabilities are unknown. Furthermore, at a time of soaring health costs, it is expensive. To justify its use will require carefully controlled and persuasive objective evidence of its benefits.
