Medial Branch Nerve Block
What is a Medical Branch Nerve Block?
A Medial Branch Nerve Block is a diagnostic and therapeutic procedure designed to identify and treat pain originating from the facet joints in the spine. The medial branch consists of small nerves that carry pain signals from these facet joints, which can become inflamed or damaged due to conditions such as arthritis, trauma, or the natural effects of aging.
The primary purpose of a medial branch block is twofold. As a diagnostic tool, it helps determine whether the facet joints are the source of a patient’s back pain. By numbing the medial branch nerves, the procedure allows physicians to assess if pain relief occurs, thereby confirming the facet joints as the pain generators. As a therapeutic procedure, a medial branch block provides pain management by temporarily numbing the affected nerves, offering relief from the discomfort caused by facet joint dysfunction. This temporary relief can help patients manage pain while exploring further treatments or improving function through physical therapy and other interventions.

Conditions Treated
• Facet Joint Arthritis (Cervical, Thoracic, or Lumbar Spine)• Chronic Neck Pain (Cervical Facet Joint Pain)• Chronic Lower Back Pain (Lumbar Facet Joint Pain)• Spondylosis (Spinal Degeneration)• Facet Joint Inflammation• Spondylolisthesis (Slipped Vertebra)• Spinal Stenosis• Radiculopathy (Nerve Root Pain)• Failed Back Surgery Syndrome (Post-Surgical Pain)• Referred Pain from Facet Joints (e.g., hips, thighs)
Benefits of Medial Branch Nerve Block
• Quick Onset of Relief: The local anesthetic in the injection provides immediate pain relief by temporarily numbing the affected nerves.• Pain & Inflammation Management: In a medial branch block, the primary medications used are local anesthetics and sometimes steroids, depending on the specific goals of the procedure. Typically, pain relief is temporary, lasting from hours or days to several weeks. • Fewer Side Effects: Medial branch nerve block may result in fewer systemic side effects than oral medications, as the anesthetic is delivered directly to the affected area.
• Diagnostic Purpose: If the pain diminishes significantly (usually by 50% or more) after the injection, it suggests that the facet joint(s) innervated by the blocked medial branch nerves are the source of the pain.• Subsequent Procedures: When a medial branch block successfully identifies the source of pain, a more permanent procedure called radiofrequency ablation (or medial branch rhizotomy) may be considered. This procedure uses heat to disrupt the medial branch nerve’s ability to transmit pain signals from the facet joint to the brain, providing longer-term relief from chronic pain. • Combination with Other Treatments: Medial branch nerve blocks are often included in a broader treatment plan. For instance, pairing nerve blocks with physical therapy, lifestyle changes, or neuromodulation can enhance long-term outcomes.• Facilitates Physical Therapy & Overall Function: By reducing pain, medial branch nerve block injections allow patients to participate more actively in physical therapy, enhancing recovery and improving mobility.• Non-Surgical Treatment: Minimally invasive, requiring no major surgery, and has a shorter recovery time than traditional surgery. • Low-risk: Low-risk option for managing spine-related pain without surgery.• Non-Surgical Treatment: Minimally invasive, requiring no major surgery, and has a shorter recovery time than traditional surgery.
• Long-Term Pain Management & Healing: Depending on patient needs and goals, staging treatment afterward with Radiofrequency ablation can help with long-term pain management. In addition, PRP and/or stem cells can address the pain's underlying cause by promoting regeneration. The healing process can provide long-term benefits, reducing the need for repeated injections or invasive surgeries.
How does the Treatment Work?
• The procedure is performed in a medical office and typically takes 30 minutes to an hour, including post-procedure monitoring.
• The skin over the injection site is cleaned and sterilized to prevent infection.• A local anesthetic will be applied to numb the skin and the tissues around the injection site, reducing discomfort during the procedure. • Under guided fluoroscopy imaging (Real-time X-ray), the physician inserts and guides a fine needle through the numbed tissue and down to the medial branch nerves. Contrast dye is injected into the area to confirm the needle’s placement. • Once the needle is in the correct position, the physician will inject a local anesthetic (and occasionally a steroid), bathing the medial branch nerves to reduce pain and swelling.• If this area is the source, immediate pain relief will occur.• More than one level of the spine may need to be injected.• Depending on the specific treatment goals and patient needs, at a later date, radiofrequency ablation, stem cells, or a combination of PRP (platelet-rich plasma) and stem cells may be utilized, promoting regeneration and overall healing.
What to Expect After Treatment?
• Mild Discomfort: You may experience soreness, numbness/tingling, and tenderness at the injection site for a few days.• Temporary Pain Increase: Some patients report a temporary increase in pain or discomfort after the procedure, which should subside within a few hours to a day.• Swelling or Bruising: Mild swelling or bruising around the injection site may occur and generally resolves within a few days.• Ice and Pain Relief: You may use ice to manage swelling or discomfort and take acetaminophen (Tylenol) and Ibuprofen (Motrin) for pain relief. Avoid NSAIDs (e.g., ibuprofen, Aleve, Advil) with cellular therapy, for the first few weeks to support healing. • Gradual Pain Relief: You may experience immediate pain relief. However, the full benefit (if a steroid was also used) may take time; it may take 1-2 days for the full effect of the medication to kick in, with more significant and longer-lasting pain relief occurring within 3-7 days.• Gradual Improvement: If Radiofrequency Ablation, PRP, and/or stem cell therapy are utilized, improvement in pain and mobility may take time, with noticeable progress occurring over 3-6 weeks. Full benefits of cellular therapy are often felt within 3-6 months.• Activity: Avoid strenuous activity, heavy lifting, or vigorous exercise for 24-48 hours after injection. If PRP and stem cell therapy are utilized, avoid strenuous physical activity or heavy lifting for 1-2 weeks to give your body time to heal and allow cellular therapy to begin working. Outside of this initial period, engaging in physical therapy or modifying activity levels can enhance the effectiveness of treatment and prolong pain relief.• Monitor Progress: Track changes in your pain levels and mobility to evaluate the effectiveness of the medial branch nerve injection(s).• Follow-up: Your healthcare provider will schedule a follow-up to assess how well the injections work and determine the next steps.
