The facet joints are located on the back of the spinal column. There are two facet joints between each pair of vertebrae, one on each side of the spine. A facet joint is made of small, bony knobs that line up along the back of the spine. Where these knobs meet, they form a joint that connects the two vertebrae.
Make an Appointment. Intraarticular Facet Joint Injections. When facet joints regularly found around the spine are inflamed, a facet joint injection is administered to relieve the irritation and diagnose where the patients pain is coming from. Once the skin and tissue above the facet joint is thoroughly numbed with local anesthetic, the physician will use a fluoroscope to insert a needle into the facet joint. The proper positioning of the needle is confirmed with the injection of contrast dye and a soothing and numbing combination of anesthetic and anti-inflammatory steroid is injected. If the pain in the facet joint is relieved upon administration of the medication,the physician will then infer that that particular facet joint is the cause of pain.
