Lumbar Epidural Steroid Injections

A lumbar epidural steroid injection (LESI) is an image guided, minimally invasive method of targeted drug therapy which is performed to relieve low back and radiating leg pain. Steroid medication can reduce the swelling and inflammation caused by conditions such as disc injuries or nerve injuries. The LESI allows placement of the anti-inflammatory medications directly at the source of inflammation. This minimizes side effects, when compared to oral medications, and increases efficacy.

How is a Lumbar epidural steroid injection performed?

Patient Positioning

The patient lies face down.

Tissue Anesthetized

A local anesthetic is used to numb the skin. All the tissue down to the surface of the lamina portion of the lumbar vertebra bone is anesthetized.

Fluoroscopic Guidance

Using a fluoroscope for guidance (live x-ray guidance), the physician directs the needle toward the epidural space and a contrast solution is injected. The physician uses the fluoroscope to confirm the correct location of the needle tip.

Steroids Injected

A steroid-anesthetics mix is injected into the epidural space, bathing the painful nerve root with soothing medication.

End of Procedure

The needle is removed and a small bandage is applied to the injection site to cover the tiny needle surface wound.

How long does it take for the LESI to work?

The lumbar epidural steroid typically takes 3-7 days before we see the full results.

Who performs a lumbar epidural steroid injection?

LESIs are performed by one of the board certified interventionalists at Spine & Nerve Diagnostic Center (SNDC). Our interventionalists have performed thousands of these procedures.

Where are lumbar epidural steroid injections performed?

LESIs are typically performed out of one of our state of the art SNDC procedure suites.
