lumbar-painA transforaminal epidural injection is a minimally invasive procedure injected under fluoroscopic guidance that can help relieve back and leg pain caused by inflamed spinal nerves. It is an injection of a long acting steroid into the opening at the side of the spine where a nerve root exits. This opening is known as a foramen. There is a small sleeve of the epidural space that extends out over the nerve root for a short distance. This epidural root sleeve is just outside the spinal canal. Sometimes these injections are referred to as root sleeve blocks, root blocks or transforaminal epidural blocks.

The long acting steroid that is injected reduces the inflammation and swelling of spinal nerve roots and other tissues surrounding the spinal nerve root. With the reduction in inflammation, irritation or swelling patients will find the benefits of reduced pain, tingling and numbness and other symptoms.

A transforaminal epidural injection is an outpatient procedure.

The Procedure

The injection takes just a few minutes, but extra time is needed to get ready.

  • Monitoring devices may be attached to your chest or side. These devices measure your heart rate, breathing, and blood pressure.
  • You lie on your stomach or side, depending on where the injection will be given. Your back is cleaned and may be covered with sterile towels.
  • Medicine is given to numb the skin near the injection site.
  • Fluoroscopy (x-ray imaging) is used for guidance and better image.
  • The transforaminal injection consists of a mixture of saline, local anesthetic, and the long acting steroid medication.

After The Procedure

You will relax in our recovery area until ready and released.

Please arrange for an adult friend or family member to drive you home afterward.
