This procedure blocks the sensory nerve supply to the facet joint. Facet joints are located between the vertebras and provide stability and flexibility to the spine. If one or more of these joints becomes inflamed or irritated, facet syndrome occurs, which results in pain.
A medial branch block is conducted to help reduce the inflammation. This procedure typically takes about 30 minutes. First, a local anesthetic is applied, followed by a fluoroscopy (x-ray) guided needle placement along the nerves that supply the joint. A local anesthetic will then be injected with possibly a steroid medication as well.
After the procedure, relief from the pain is usually experienced within minutes. However, patients are asked to record their pain level for the first few days following this procedure.
