Facet Block Injection

What is a facet block injection and how is it performed?

A facet block injection is a treatment that provides temporary relief of back pain, as well as a test to find out whether facet joints are the source of a patient’s back pain. The injection is inserted into the facet joints, which are located on each side of the vertebra and connect the vertebra of the back together. The injection helps reduce inflammation in the tissue of the facet joint. The injection is performed with the patient lying on his or her abdomen. Prior to the injection, the area of the skin where the medication will be injected is cleaned and numbed with local anesthetic. With the use of fluoroscopy (live x-ray), the radiologist injects a mixture of local anesthetic and steroid medication into the facet joint.

Before the Procedure:

Once scheduled for a nerve root block, you will be contacted by one of the spine nurses. You will be asked to provide information regarding your current problem, past medical history, and medications. She will provide you with detailed instructions on how to prepare for the upcoming procedure. You must bring your most recent MRI with you. You will be asked to hold any blood thinning medications such as Coumadin, Plavix, Aspirin, and any NSAIDS. Any insurance questions can be answered by your referring physician.

The Day of the Procedure:


For your convenience, we ask that you utilize valet parking upon arrival. You will then report to the 1st floor admitting desk to be registered. Once they have your insurance information, you will be directed to the radiology reception desk. The attendants there will validate your parking ticket for a discounted rate and show you to the waiting area where the spine nurse will meet you.
