Medial Branch Blocks

Medial Branch Blocks are used as an initial measure for back pain reduction. An anesthetic is injected into the affected area of the spine to reduce inflammation and pain.


Medial Branch Blocks

A medial branch block is diagnostic procedure used to identify a painful facet joint. Facet joints are located in the rear of the spine on each side and connect each vertebra in the spine with the two vertebrae above and below it.

The patient lays on their stomach while the doctor injects a local anesthetic in the area surrounding the facet joint suspected to be the source of pain. The doctor then begins the minimally invasive AccuCision® Spine procedure by inserting a needle into the skin. The doctor then uses a special x-ray device and an injection of contrast dye to confirm the needle is in the correct location. Once the needle is positioned properly, anesthetic medication is injected in the area, temporarily blocking the sensation of a group of small nerves, called the medial branch nerves. These nerves carry pain signals from the facet joints to the brain. If the injection relieves the patient’s pain, then the source of the pain has been determined, and the doctor can inject a more long-lasting anesthetic. If the injection does not relieve the pain, the doctor may test nearby facet joints to identify the correct pain-causing joint.
