Insights
Functional posterior rhizotomy significantly reduced spasticity in a child with cerebral palsy, improving daily activities and offering long-term benefits. This neurosurgical treatment is effective for managing spastic cerebral palsy.
Area of Science:
- Neurosurgery
- Pediatric Neurology
- Rehabilitation Medicine
Background:
- Spastic cerebral palsy (CP) significantly impairs daily activities and caregiver burden.
- Functional posterior rhizotomy is an established neurosurgical treatment for spastic CP in North America but is less common in Japan.
Observation:
- A case study of a 4-year-old boy with severe spastic CP is presented.
- The patient underwent selective dorsal rhizotomy, involving cutting specific spinal nerve rootlets (L2-S1) based on neurophysiological testing.
- Preoperative activities of daily living (ADL) were severely restricted due to spasticity.
Findings:
- Postoperative spasticity markedly decreased, leading to improved ADL.
- The positive effects on spasticity control were long-standing during over 1.5 years of follow-up.
- Residual spasticity subsided over time.
Implications:
- Functional posterior rhizotomy is a valuable neurosurgical option for treating spasticity in pediatric cerebral palsy.
- This procedure can significantly alleviate patient and family burden associated with severe spasticity.
- Combining rhizotomy with existing treatments may offer enhanced benefits for individuals with spastic CP.
Abstract:
The author reported a case of spastic cerebral palsy in a 4-year-old boy who underwent functional posterior rhizotomy and were followed up for more than one and a half years after surgery to evaluate the degree of spasticity. The patient's preoperative ADL was highly restricted due to severe spasticity. In the surgery, the bilateral rootlets from L2 to S1 were selectively cut if an abnormal reflex activity was demonstrated by neurophysiological methods. Spasticity markedly decreased postoperatively and alleviated the family's burden for daily care. During the period of follow up, residual spasticity has subsided and the effect in controlling spasticity was long-standing. Functional posterior rhizotomy has been recognized as an established neurosurgical treatment for spastic cerebral palsy in childhood in the North America. However, the procedure is uncommon in Japan. The author outlined here the procedure and its history. Functional posterior rhizotomy is a strong armament for treating spasticity in cerebral palsy. The procedure would greatly benefit patients with spastic cerebral palsy in combination with current treatments.
