Medial Branch Block Injections

Medial branch block is an injection of a local anaesthetic near the medial branch nerves to temporarily block the pain signal carried from the facet joints of the spine to the brain. It is used to assist your physician in diagnosing the cause of your back pain. Facet joints are the joints connecting the different vertebrae of the spine to each other. Medial branch nerves are small nerves that supply the facet joints of the spine.
