There are many applications of this technique, but most commonly, this term refers to the interruption of the nerves that carry the signal from the facet joints. This is done similarly to medial branch blockade, except with special needles that allow for a thin wire-like probe to be placed through the needles. Energy is then transmitted through the probe in an effort to interrupt the nerve signal. This can often provide extended relief of pain that comes from the facet joints, and can be repeated down the road if necessary. If you have a pacemaker or similar device, special preparations may be required.
