What are Facet Joints?

The facet joints are paired joints located at the back of the spine, which connect the adjacent vertebrae together and provide stability to the spine. The facet joints in the neck are referred to as cervical facet joints. They are supplied by nerves that carry pain signals to the spinal cord and to the brain.

Why are Cervical Facet Blocks Administered?

What is the Procedure for a Cervical Facet Block?

During the injection procedure, you will be placed on your stomach, on the X-ray table. Your physician will clean the intended site on your neck with antiseptic and cover it with a sterile drape. A local anesthetic is then used to numb the skin. You may feel a stinging or burning sensation for a few seconds.

A needle is directed into the facet joint under X-ray (fluoroscopy) guidance. Following this, a local anesthetic with or without steroid will be slowly injected through the needle. The needle is then removed and a bandage is placed to cover the injection site.

You should arrange for someone to drive you home after the procedure. Avoid swimming or soaking in a tub, pool or Jacuzzi and the application of any form of heat to the injection site for the rest of the day following your procedure.Keep a record of the degree of pain relief and its duration.
