Introduction.

In this chapter, the current status of dorsal rhizotomy is reviewed, highlighting its significant evolution over the past four decades. The first major advancement was sparked by Fasano's introduction of intraoperative neurophysiological procedures and Peacock's modification of the surgical site to the cauda equina. Subsequent advancements in surgical and neurophysiological techniques have expanded the indications for rhizotomy beyond spastic cerebral palsy, a condition affecting 0.2% of live births worldwide. Dorsal rhizotomy can significantly benefit children with spasticity by improving their mobility, daily activities, and social participation.
