WHAT ARE THORACIC FACET JOINTS?

Facet joints connect the vertebrae, the bones of the spine. They help guide your spine when you  move. The section of your spine between your neck and low back is called the thoracic region. It contains twelve vertebrae. Facet joints are found on both sides of the spine. Each is about the size of a thumbnail. Thoracic facet joints are named for the  vertebrae they connect and the side of the spine where they are found. The right T4-5 facet joint, for example, joins the 4th and 5th thoracic vertebrae on the right side. Medial branch nerves are found near facet joints. They communicate pain from the facet joint.  They tell the brain when a facet joint has been injured.

WHAT IS THORACIC FACET JOINT PAIN?

You may feel pain if a thoracic facet joint is injured. Sometimes it feels like muscle tension.  Other times it can be severe pain. The cartilage inside the joint may be injured. Other times only connecting ligaments surrounding  the joint are injured. Facet pain also depends on which joint is affected. Thoracic facet joint pain can occur in an area from your upper back and shoulder down to your hips. The diagram shows areas of pain usually associated with thoracic facet injuries.

HOW DO I KNOW IF I HAVE THORACIC FACET PAIN?

If you have pain in one or more of these areas, and it has lasted longer than two months, you may have thoracic facet pain. Common tests such as X-rays or MRIs may not always show if a facet joint is causing pain. The best way to diagnose facet pain is to block the  pain signal in a medial branch nerve.

WHAT IS A THORACIC RFA?

RFA uses radiofrequency energy to disrupt nerve function. When this is done to a thoracic medial branch nerve, the nerve can no longer transmit pain signals from an injured facet joint.

WHAT HAPPENS DURING AN RFA?

An RFA may start with an IV (medicine given intravenously) to help you relax. A local anesthetic may be used to numb your skin. The doctor will then insert a thin needle near the facet joint. Fluoroscopy, a type of x-ray, will be  used to position the needle. The doctor will then check to make sure it is at the correct nerve by stimulating it. This may cause muscle twitching and provoke some of your pain. Once the needle is properly placed, the area will be numbed. Radiofrequency energy will then be  used to disrupt the medial branch nerve.

WHAT HAPPENS AFTER AN RFA?

You will be monitored for up to 30 minutes after the RFA. When you are ready to leave, the  clinic will give you discharge instructions. You will also be given a pain diary. It is important to fill this out because it helps the doctor know  what the next step will be. Take it easy for the rest of the day. You may feel sore for one to four days. This is normal. It may be due to muscle and nerve  irritation. Your back may feel numb, weak, or itchy for a couple weeks. Full pain relief normally comes in two to three weeks.

HOW LONG CAN I EXPECT PAIN RELIEF?

Nerves regenerate after an RFA, but how long this takes varies. Your pain may or may not return  when the nerves regenerate. If it does, another RFA can be done.
