Dorsal Rhizotomy Information

Dorsal rhizotomy is a surgical procedure used in the treatment of some cases of cerebral palsy. The procedure is typically performed on children; however, some adults may also qualify.

Purpose

• The purpose of the procedure is to reduce a symptom of cerebral palsy called spasticity. Spasticity is defined, according to the Mayo Clinic, as stiffness of the muscles and an exaggeration of reflexes.

Procedure

• The procedure involves exposing the lower portion of the spinal cord and testing the dorsal nerves, those that send information to the spine from the limbs, for abnormal function. Those nerves exhibiting abnormal function are cut.

Outcomes

• The St. Louis Children's Hospital reports that dorsal rhizotomy produces long-term reduction of spasticity in those with spastic diplegia (lower limbs), but that spasticity is likely to recur with spastic quadriplegia (all limbs).

Risks

• The risks involved with dorsal rhizotomy can include lower limb paralysis, sensory changes and infections.

Physical Therapy

• Following a dorsal rhizotomy, physical therapy is standard procedure. The duration of physical therapy is evaluated on a case by case basis, but the Cleveland Clinic reports an average of three to six months.
