Thoracic Transforaminal Epidural Steroid Injections

Thoracic Transforaminal Epidural Steroid Injections - for upper mid and back pain

A thoracic transforaminal epidural steroid injection is an outpatient procedure for treating upper and middle back pain.

This information will explain what it is, Dr. Singer can determine if it is for you.

What is the epidural space? The dura is a proactive covering of the spinal cord and its nerves. The space surrounding the dura is called the epidural space. In the upper back it is called the thoracic epidural space.

What causes pain in the epidural space? The thoracic area of the spine has twelve bones, called vertebrae. Soft discs found between them cushion them, hold them together, and control motion. If a disc tears, chemicals may leak out. This can inflame the dura or nerve roots and cause pain. A large disc tear may cause a disc to bulge, inflaming the dura and nerve roots, and cause pain. Bone spurs, called osteophytes, can also press against the nerve roots and cause pain.

How do I know if I have disc and nerve root pain? If you have pain in your upper back when you move, you may have thoracic disc or dural inflammation. If pain travels to the front of your chest when you move your upper or mid back, you may have nerve root inflammation. Common tests such as MRIs can show disc bulges and nerve root compression, but may not show a torn and leaking disc. A thoracic epidural injection may provide relief if disc, dural, or nerve root inflammation is causing your pain.

What is a thoracic transforaminal epidural steroid injection? In a thoracic epidural injection a corticosteroid (anti-inflammatory medication) is injected into the epidural space to reduce inflammation. A local anesthetic (numbing medicine) may also be injected. When it is done from the side where the nerve exists the spine, it is called a transforaminal injection. This technique puts the medication near the source of the inflammation.

What happens during an injection? A local anesthetic will be used to numb your skin. The doctor will then insert a thin needle directly into the epidural space. Fluoroscopy, a type of x-ray, must be used to ensure the safe and proper position of the needle. A dye may be used to make sure the needle is at the correct spot. Once Dr. Singer is sure the needle is correctly placed, the medicine will be injected.

What happens after an injection? You will be free to get re-dressed and check out at the front desk. It may help to move your upper and mid-back neck in ways that hurt before the injection, to see if the pain is still there, but do not overdo it. Take it easy for the rest of the day. You may feel immediate pain relief and some numbness in your upper and mid-back for a limited time after the injection. This may indicate the medication has reached the right spot. You can usually return to work the day after the injection. Your pain may return after this short pain-free period or may even be a little worse for a day or two. It may be caused by needle irritation or by the steroid itself. Steroids usually take two or three days to start working, but can take as long as a week.

How long can I expect pain relief? The extent and duration of pain relief may depend on the amount of disc, dural or nerve root inflammation. Other coexisting factors may be responsible for your pain. Sometimes an injection brings several weeks to months of pain relief and then further treatment is needed. Other times, a single injection brings long-term pain relief. If your pain is caused by injury to more than one area, only some of your symptoms may be helped by a single injection.
