Medial branch nerves are small nerves that feed out from the facet joints (joints located between and behind adjacent vertebrae) in the spine and carry signals from those joints to the brain. Using fluoroscopy (x-ray guidance), an anesthetic is injected near your medial nerves to temporarily interrupt the pain signal being carried.
A Medial Branch Nerve Block is a diagnostic procedure, meaning it is used to identify your pain source. If you have the appropriate duration of pain relief after the medial branch nerve block, you may be a candidate for Medial Branch Nerve Ablation (an injection procedure in which a heat lesion is created on certain nerves with the goal of interrupting the pain signal to the brain, which can last nine to fourteen months).
