This minimally-invasive procedure, also called radiofrequency, reduces or eliminates the pain of damaged facet joints of the neck and shoulders 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 medial branch nerves. Then, a radiofrequency electrode is inserted through the cannula, which heats and cauterizes the nerve. This disrupts its ability to communicate with the brain, blocking the pain signals.
All injections are performed under fluoroscopy (x-ray) guidance.
