Selective dorsal rhizotomy, also known simply as rhizotomy or selective posterior rhizotomy, is a neurosurgical procedure that selectively cuts problematic nerve roots in the spinal cord. It is used to relieve the symptoms of neuromuscular conditions such as spastic diplegia and other forms of spastic cerebral palsy, with the sensory nerves inducing spasticity identified using electromyographic stimulation and graded before the abnormal ones are cut.
Facts
Partially Attested
Origin YearWikipedia dates the selective technique to 1978 (Fasano); non-selective dorsal rhizotomy for spasticity was reported earlier in 1913 (Foerster). FAQs
Who is considered a candidate for selective dorsal rhizotomy?
Mainly children with severe leg spasticity who can take part in therapy, judged case by case.
Candidacy is decided case by case by a specialist team, and criteria differ between centers. The Children's Hospital of Philadelphia describes its primary candidates as children whose main problem is severe muscle spasticity in the legs that limits mobility, and who can follow directions and take part in therapy, because the surgery requires extensive rehabilitation. The same center says children with severe spasticity in both their arms and legs may also be candidates. For them the goal is greater independence, such as sitting for longer periods or controlling movement in a wheelchair, and easier care, rather than walking. This describes one hospital's published practice and is not medical advice.
