What is a rhizotomy?

A dorsal rhizotomy is a surgery done to, among other things, improve tone imbalances in children with cerebral palsy. The surgery involves isolating over active nerve rootlets within the nerves that service the legs and then cutting some or all of the these rootlets resulting in the lowering of tone. this makes it easier for these children to move their legs and relaxes their lower body in general. As a result, children who cannot walk due to high tone are sometimes able to walk independantly or with aides such as walkers or canes.


How often can a rhizotomy be repeated?

A rhizotomy can typically be repeated if the initial procedure's effects diminish over time, which is common as nerve pathways may regenerate. However, the frequency of repeat procedures depends on individual patient factors, the underlying condition being treated, and the patient's response to the first procedure. It's essential to consult with a healthcare provider to determine the appropriate timing and necessity for repeat rhizotomy based on specific circumstances.
