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.
Using a fluoroscope, the physician locates the appropriate lumbar vertebra and nerve root. Local anesthetic is used to numb the skin and all tissue down to the surface of the lamina portion of the lumbar vertebra bone. The physician slides a thicker needle through the anesthetized track and guides it toward the epidural space between vertebra. A contrast solution is injected and the physician uses the fluoroscope to see the painful areas and confirm the correct location of the needle tip. A mix of anesthetics and steroid is injected into the epidural space, bathing the painful nerve root with soothing medication.
