selective dorsal rhizotomy
A neurosurgical procedure that selectively cuts sensory nerve roots to reduce spasticity in children with cerebral palsy.
Full Definition
Selective dorsal rhizotomy (SDR) is a neurosurgical intervention designed to permanently reduce spasticity in carefully selected children with cerebral palsy, primarily those with spastic diplegia. The procedure involves making a laminectomy and selectively cutting sensory nerve rootlets that contribute to spasticity while preserving those that support normal function. Candidates must demonstrate good underlying strength, selective motor control, and motivation for intensive post-operative rehabilitation. The surgery can improve mobility, reduce pain, and enhance quality of life, but requires extensive physical therapy for optimal outcomes.
Usage
Usage note: Always specify 'selective' to distinguish from complete dorsal rhizotomy.
