This minimally-invasive procedure, also called radiofrequency, reduces or eliminates the pain of damaged facet joints of the back by disrupting the medial branch nerves that carry pain signals.
X-ray guidance is used to carefully guide a needle-like tube (cannula) to the irritated medical branch nerves. Then, a radiofrequency electrode is inserted through tube, which heats the nerve. This disrupts its ability to communicate with the brain, blocking the pain signals.
All injections are performed under fluoroscopy (x-ray) guidance
