Medial Branch Block
Medial Branch Nerve Blocks
A medial branch nerve block is part of a 2-step diagnostic and treatment approach. The procedure involves injecting an anesthetic near small medial nerves connected to a specific facet joint. It is possible to inject several areas of the spine in one procedure. If a patient experiences a great deal of pain relief from the medial branch nerve block injection, the facet joint is determined to be the source of pain. If the pain relief lasts for a duration of time following the medial branch block, the patient may then be a candidate for a subsequent procedure known as radiofrequency ablation. The radiofrequency ablation offers a longer term pain relief.
