Lumbar Epidural Steroid Injection

 

Overview
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.

 

 



Patient Positioning
The patient lies 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.

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. The
physician slides a thicker needle through the
anesthetized track.

Fluoroscopic Guidance
Using a fluoroscope for guidance, the physician
slides the needle toward the epidural space
between the L-4 and L-5 vertebra. 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 cover the tiny needle surface wound. 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.
