Rhizotomy/Denervation

In a rhizotomy, sensory nerve pathways are interrupted by destruction of the sensory nerves by a temperature monitored electrode.

How is Rhizotomy done?

A rhizotomy, also known as a percutaneous facet denervation, is performed by placement of a temperature-monitored electrode with the help of a C-arm with the image intensifier (X-ray) for accurate radiological positioning. The electrode serves to make percutaneous radiofrequency lesions (destruction of the sensory nerves) and therefore interrupt the sensory nerve pathways.

You will be given intravenous sedation during the procedure, while your vital signs are monitored.

A Rhizotomy has a very unlikely occurrence of any side effects or complications.

How do I get ready for a Rhizotomy?

You should not eat or drink after midnight prior to the procedure. In addition, you must bring someone with you to drive you to and from your appointment.

If you are on routine medications for heart or blood pressure, take your medication as usual with a small sip of water.

Post operative course?

Sometimes weakness in the arm and leg immediately following the procedure may happen. This is due to leakage of local anesthetic solution onto the main nerve that will resolve in 1 to 2 hours. It can be expected that you may have peri-operative discomfort 1 to 2 weeks following the procedure.
