Nerve Root Block

A nerve root block (or a facet block) is the placement of a needle and injection of a combination of local anesthetic and steroid into the sheath surrounding a nerve root in the spine. A block is performed to determine if a specific spinal nerve root is the source of pain and reduce inflammation around the nerve root thus decreasing or relieving the pain. Franklin Moser, MD, director of Neuroradiology, heads our team of imaging physicians, nurses and technologists who specialize in this procedure.

Why Has My Doctor Ordered a Nerve Root Block?

The facet block is a diagnostic test to localize the source of your pain by determining if your pain responds to the injection of medication. Alternatively, this procedure is used to treat symptoms arising from facet joint arthritis.

How is the Nerve Root Block Procedure Performed?

The precise location for the needle placement is determined with imaging guidance. You may experience brief, temporary sensations of pain or an electric shock sensation down the leg. Iodinated contrast is injected to confirm the location of the needle tip.
