What Is An Epidural Steroid Injection?

An epidural steroid injection (ESI) is a minimally invasive procedure that can help relieve neck, arm, back, and leg pain caused by inflamed spinal nerves. ESI may be performed to relieve pain caused by spinal stenosis, spondylolysis, or disc herniation. Medicines are delivered to the spinal nerve through the epidural space, the area between the protective covering of the spinal cord and vertebrae. The effects of ESI tend to be temporary. Pain relief may last for several days or even years. The goal is to reduce pain so that you may resume normal activities and a physical therapy program.

What is an epidural steroid injection (ESI)? An epidural steroid injection includes both a long-lasting corticosteroid (e.g., triamcinolone, betamethasone) and an anesthetic numbing agent (e.g., lidocaine, bupivacaine). The drugs are delivered into the epidural space of the spine, which is the area between the protective covering (dura) of the spinal cord and the bony vertebrae (Fig. 1). This area is filled with fat and small blood vessels (see Anatomy of the Spine).

Corticosteroid injections can reduce inflammation and can be effective when delivered directly into the painful area. Unfortunately, the injection does not make a herniated disc smaller; it only works on the spinal nerves. The pain relief can last from days to years, allowing you to improve your spinal condition with physical therapy and an exercise program.
