Children with spastic cerebral palsy who can’t walk at the age of 4 can be evaluated and treated with surgery. Surgery is mainly for children with spastic cerebral palsy or cerebral palsy with severe bone and joint deformities, which can be categorized into neurological and orthopedic surgery. 1. Indications for surgery: The indications for surgery are mainly for children with cerebral palsy with severe bone and joint deformities or spastic cerebral palsy. Surgery can be performed to relieve spasticity of the limbs, reduce muscle tone, and correct contracture deformities of the bones, joints and soft tissues. 2. Post-operative rehabilitation is needed to help children recover better: (1) Neurosurgery: Posterior spinal nerve rhizotomy is mostly chosen, which can reduce the excitatory input to the motor neurons, thus relieving the limb spasm. This procedure involves laminectomy and cauda equina exposure, electrical stimulation of the posterior roots, and severing of more nerve fiber roots that cause abnormal reflexes. (2) Rehabilitation: Rehabilitation is needed after surgery to better restore muscle strength and help maximize the child’s recovery. Parents of children with spastic cerebral palsy should bring them to the hospital in time for standardized treatment under the guidance of doctors.
