Medial Branch Block

Medial branch blocks are injections of anesthetic that have proven effective for both diagnosing and treating back pain.

Benefits of Medial Branch Block

Medial branch nerves are small nerves that spread out from the spinal facet joints and carry pain signals to the brain. A medial branch block is a procedure that aims to identify the medial branch nerve that is the source of the patient’s pain, then treat the condition to alleviate or lessen the pain.

Details of the Medial Branch Block

Medial branch blocks are often employed as the first stage in a two-stage diagnostic and treatment approach. During the procedure, an anesthetic is injected near small medial nerves connected to a specific facet joint. Usually, several levels of the spine are injected in one procedure. If the patient experiences significant pain relief immediately after the procedure, then the facet joint is determined to be the source of the patient’s pain.

Medial branch block functions primarily as a diagnostic tool. If the patient has an appropriate period of pain relief after the procedure, he or she may be a candidate for a subsequent procedure that may result in longer-term pain relief.

Preparing for the Medial Branch Block

Before receiving a medial branch block, most physicians will require an MRI or CT-scan to get a better picture of what could be causing the pain. Often, a medial branch block injection is often just one portion of the conservative treatment method a physician may suggest to treat back or neck pain. Other methods include physical therapy and chiropractic adjustments. If these conservative methods have not produced meaningful, long-lasting relief, you may be a candidate for a surgical North American Spine procedure.

Most patients will be able to return to normal activities the next day, though the injection site may have some dull soreness. Side effects–including headaches and infections–are rare. Your physician will counsel you on these risks prior to the procedure.

Connect With A Patient

Some of our former patients have been kind enough to offer to speak with back and neck pain sufferers who are looking into treatment options. We encourage you to take them up on it! After we determine a treatment plan, we’ll connect you with a past patient who had a similar condition and procedure.
