Medial Branch Blocks

Medial Branch Blocks

Medial branch blocks can be used independently to provide long-term pain relief. They can also be used to precisely identify the facet joints as the cause of pain, and are the preliminary procedure prior to radiofrequency neurotomy of the medial branch nerves.

A medial branch block interrupts the sensory nerve supply to the involved facet joint through the use of a precise administration of an anesthetic agent and steroid. After a local skin anesthetic is applied, the physician uses fluoroscopy (x-ray) guidance to place a needle along the nerves that supply the inflamed joint.
