What is a transforaminal lumbar epidural steroid injection?
A transforaminal lumbar epidural steroid injection (TFESI) is an injection of corticosteroids (anti-inflammatory medication) into the epidural space. When it is done from the side where the nerve exits the spine, it is called a transforaminal injection. It puts 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 moving x-ray, must be used to ensure the safe and proper placement of the needle. A dye may also be used to make sure the needle is at the correct spot and the medication will spread properly.
How do I prepare for the procedure?
A lumbar transforaminal epidural steroid injection is a minor surgical procedure that is typically performed at an ambulatory surgery center. You should not eat or drink anything for at least 2 hours before your procedure. You should take all of your medicines except blood thinners the day of your procedure.
