Lumbar Epidural Steroid Injection


This injection procedure is performed to relieve low back and radiating leg pain. Steroid medication can reduce the swelling and inflammation caused by spinal conditions. In some cases it may be necessary to repeat the procedure as many as three times to get the full benefit of the medication. Many patients get significant relief from only one or two injections.

Fluoroscopic Guidance

The patient lays face down. A cushion under the stomach area provides comfort and flexes the back. In this position, the spine opens and allows for easier access to the epidural space. A fluoroscope assists the physician in locating the appropriate lumbar vertebra and nerve root. A local anesthetic is used to numb the skin.

  1. Tissue Anesthetized
    All the tissue down to the surface of the lamina portion of the lumbar vertebra bone is anesthetized.
  2. Larger Needle Inserted
    The physician slides a thicker needle through the anesthetized track.
  3. Needle Guided
    Using fluoroscope for guidance, the physician slides the needle toward the epidural space between the L-4 and L-5 vertebra.
  4. Contrast Dye Injected
    A contrast solution is injected. The physician uses the fluoroscope to see the painful areas and to confirm the correct location of the needle tip.
  5. Steroids Injected
    A steroid-anesthetics mix is injected into the foraminal epidural space, bathing the painful nerve root with medication.
