Radiofrequency Denervation (Rhizolysis)
Radiofrequency denervation (RFD) is a minor procedure performed by one of our pain specialists. It is used to treat pain arising from one or more facet joints, and is generally carried out after the diagnosis has been confirmed by facet joint blocks.
RFDs invovle either local anaesthetic and/or light sedation. They are done with the assistance of either X-rays or a CT scan, and you will be able to return home a couple of hours later.
Using X-ray or CT, a small probe is inserted through the skin and targets the nerves which provide sensation to the affected joint. By heating these nerves, the pain signals from the joint are frequently reduced, and the associated pain decreases or disappears.
In cases where the pain returns after several months, this procedure can be repeated.
