Medial branches are very small nerves that are supposed to transmit information regarding the facet joints of the spine to the brain. If these nerves are disabled or blocked, they will not be able to transmit the information and pain will thus not be felt.

This treatment is clinically recommended by most specialists to determine whether the facet joints are causing the pain in the back or the legs. The facet joints are located between each vertebra and allow us to bend our backs and move each vertebra independently.

The procedure starts with cleaning the back with an antiseptic solution, after which the clinicians inject the medicine in the nerve using an X-ray vision machine. If the procedure is successful, doctors usually recommend patients to opt for radiofrequency treatments of the medial branch.
