This is a certain type of epidural injection using a small amount of anti-inflammatory steroid into the bottom portion of epidural
space (outside the spinal cord, in the low back area). This procedure has the capacity of treating or at least decreasing the
inflammation or irritation of the spinal cord or spinal nerves.
A herniated or bulging disks, bone spurs, narrowed spinal canal (spinal stenosis), arthritis changes, or scar tissue from
previous spine surgeries (arachnioditis) all can irritate the spinal cord or spinal nerves and cause pain, numbness, and
weakness. This type of pain, referred to as radicular or sciatic-like pain, is felt in the area of the body that the irritated
nerves(s) go to (innervate). If the irritation or inflammation is treated effectively, then possibly all of the pain, numbness, or
weakness will resolve. It can prevent, or at the very least postpone; the need for surgery.
Patient will be placed prone (face down). The back will be cleansed with an antiseptic, and then numbed near the tailbone.
Using live X-ray (fluoroscopy) the needle will be guided into the epidural space, and the steroid, often mixed with local
anesthetic (like Novocain) and various amount of normal saline (as a volumizer); will be injected. Radicontrast solution is
always used to confirm proper needle placement before the injection. This procedure can be associated with transient feelings
of tingling, warmth, numbness, and weakness in the legs for up to a few hours after the injection. The procedure may take up
to 30 minutes. After the injection, the patient will rest for 15 minutes while the nurse monitors the blood pressure and pulse. A
Band-Aid will be applied to the injection site. A nurse will review the discharge instructions with the patient before going home.
