Transforaminal or Selective Nerve Root Block

What is a Transforaminal or Selective Nerve Root Block?

A Transforaminal or Selective Nerve Root Block is a minimally invasive procedure designed to diagnose and treat pain resulting from nerve root inflammation or irritation. During the procedure, a carefully guided injection containing a local anesthetic, and, in some cases, a steroid medication is administered near the affected nerve root. This helps to alleviate pain by reducing inflammation and blocking the pain signals from the affected nerve root.

What to Expect

How long does the procedure take?

The procedure typically takes about 15 to 30 minutes, depending on the number of nerve roots being treated.

Will it hurt?

The procedure is performed under local anesthesia, minimizing discomfort. Some patients may experience slight pressure or discomfort during the injection.

Are there any risks?

While Transforaminal or Selective Nerve Root Blocks are generally safe, there are potential risks, including infection, nerve damage, bleeding, or allergic reactions. Your pain management specialist will discuss the risks and benefits with you before the procedure.

How long will the results last?

The duration of pain relief varies from patient to patient. Some may experience immediate relief that lasts for several months, while others may require multiple injections for optimal and sustained relief.

Will I use this in combination with other treatments?

Your pain management specialist may recommend this procedure as a standalone treatment or in conjunction with other therapies, such as physical therapy, medication management, or chiropractic care, to achieve the best possible outcomes.

Tips to Get Ready for the Epidural Steroid Injection Procedure

• Follow your healthcare provider’s instructions regarding medications, especially if you are on blood thinners or have diabetes.
• Arrange for someone to drive you home after the procedure, as you may experience temporary weakness or numbness in the treated area.

What Happens During the Procedure?

Before the procedure, you will lie on an examination table, and your skin will be cleansed and numbed. Using fluoroscopy (X-ray guidance), your pain management specialist will carefully guide a thin needle to the targeted nerve root. Once the needle is correctly positioned, the medication will be injected.

Post-Operative Care

After the procedure, you will be monitored for a short period to ensure there are no immediate complications. You may experience some temporary soreness at the injection site, but this can usually be relieved with ice packs. It is essential to rest for the remainder of the day and avoid strenuous activities.

• Follow your pain management specialist’s aftercare instructions carefully.
• Pay attention to any signs of infection or unusual side effects and promptly contact your healthcare provider if you experience any concerns.
