Lumbar Epidural Steroid Injection

What is the epidural space?

The membrane that covers the spinal cord and nerve roots in your spine is called the dura membrane. The space surrounding the dura is the epidural space. Nerves travel through the epidural space into your legs. Inflammation of these nerve roots may cause pain in these regions due to irritation from a damaged disc or from contact with the bony structure of the spine in some way.

What is an epidural and why is it helpful?

An epidural injection places anti-inflammatory medicine into the epidural space to decrease inflammation of the nerve roots, hopefully reducing the pain in your legs. The epidural injection may help the injury to heal by reducing the pain in your back and/or legs. The epidural injection may help the injury to heal by reducing inflammation. It may provide permanent relief or provide a period of pain relief for several months while the injury/cause of your pain is healing.

What will happen to me during the procedure?

An IV will be started so that relaxation medication can be given. You will be placed on the X-ray table on your stomach in such a way that your doctor can best visualize your back using x-ray guidance. The skin on the back of your neck will be scrubbed with two types of sterile (soap) scrub. Next, the physician will numb a small area of skin with numbing medicine. The medicine stings for several seconds.

After the numbing medicine has been given time to be effective, your doctor will direct a very small needle using x-ray guidance. A small amount of contrast (dye) is then injected to insure proper needle position inside the joint space. Then, a small mixture of numbing medicine (anesthetic) and anti-inflammatory (cortisone/steroid) will be injected.

What will happen after the procedure?

Immediately after the procedure, you will move around and try to imitate something that would normally bring about your usual pain. You will then be sent to the recovery area to be monitored for 30-60 minutes. You will then report the percentage of pain relief and record the relief you experience during the next week on a post injection evaluation sheet (diary). This will be given to you when you are discharged home.

You will not be able to drive the day of your procedure. On occasion, your arms may feel weak or numb for a few hours. If your arms do get weak or numb, it usually does not last more than a few hours. You may be referred to a chiropractor or physical therapist immediately afterwards while the numbing medicine is still working.
