Transforaminal Nerve Root Blocks

Overview

A Transforaminal Nerve Root lock is a procedure in which steroid medication is injected near the nerve root as it exits the spinal column. This procedure is used both to relieve neck and back pain and to identify the precise source of the pain.

Many individuals who undergo this procedure experience pain relief that lasts for several months, and some may even experience permanent pain relief. It is considered an effective treatment option for those suffering from neck and back pain.

There is a small risk of complications associated with a transforaminal nerve root block, although these are rare. Some possible complications include:

1. Pain: Some patients may experience temporary pain, including a temporary increase in pain levels at the injection site.
2. Changes in blood pressure
3. Infection: While rare, there is a risk of infection at the injection site.
4. Bleeding: There is a small risk of bleeding, especially for patients on blood-thinning medications or with bleeding disorders.

It’s important to discuss the risks and benefits of the procedure with your healthcare provider before undergoing a transforaminal nerve root block.

Procedure

During a transforaminal nerve root block procedure, you will be taken to the X-ray room, where you’ll be helped onto a table. Once you’re comfortable, your skin will be cleaned with an antiseptic, and the area will be numbed with a local anesthetic. Your doctor will then place a small needle near the affected nerve using X-ray guidance. A small amount of contrast dye may be used to ensure the needle is in the correct area. Once the needle is in place, the steroid medication will be injected. The entire procedure typically lasts only a couple of minutes.

The anesthetic used can make your arms and legs feel weak or numb, so it’s advised to stay with the healthcare team for 15 to 20 minutes after the procedure. During this time, a nurse will address any questions you may have and review your discharge instructions and required follow-up care.

What to expect afterwards:

After a Transforaminal Nerve Root Block, it’s advisable to rest and avoid activities that may exacerbate your back or neck pain. Most patients can return to work the same day and resume exercising the next day if there is no pain or discomfort.

You may experience some pain or discomfort at the injection site for the first 48 hours after the procedure. Applying ice to the injection site or taking over-the-counter pain medications can help alleviate any discomfort.

While many patients experience pain relief after the first or second injection, some may require up to three injections. If your pain does not immediately subside, do not be discouraged. Follow up with your doctor or consider another injection in two or three weeks.
