Medial Branch Block

Medial Branch Block

Medial Branch Blocks are diagnostic procedures to determine the source of your back pain. Medial Branch Nerves come from the spinal cord and innervate the zygapophyseal joints. If numbing this nerve relieves pain, an appropriate treatment plan can be made. After successful Medial Branch Blocks, the next step would be to perform a Radiofrequency Ablation, which cauterizes the Medial Branch Nerves and provides longer lasting relief. Of note, most insurances require 2 MBBs for approval of radiofrequency ablation.

For this injection you will need a driver from the procedure if oral sedation is used. Activity after the injection is as tolerated.

The desired effect is short-term (a couple days) pain relief of around 80%.

Complications may include bleeding, infection, pain at the site of injection, redness/irritation at the site of injection, or allergic reaction. A complete list of risks and complications will be provided before any procedure.
