Medial Branch Nerve Block
Procedures
Minimally Invasive Injections
A medial branch nerve block is a minimally invasive injection that temporarily numbs the small nerves (medial branches) transmitting pain from the spine’s facet joints. Holistiq Spine & Orthopaedic Clinic offers this advanced procedure as part of a comprehensive, integrative approach to managing spine pain, combining clinical expertise with holistic wellness support.
What Is a Medial Branch Nerve Block?
A medial branch nerve block involves precisely injecting a local anesthetic, sometimes with a corticosteroid, near the medial branch nerves running alongside the facet joints in the spine. This temporarily blocks pain signals and helps diagnose or treat pain linked to these joints.
What Conditions & Types of Pain Does It Treat?
- Facet joint syndrome: Often caused by arthritis, degeneration, or injury.
- Chronic neck and lower back pain: Especially when linked to spinal joint inflammation.
- Pain from spinal osteoarthritis, spondylosis, or mechanical back pain.
Who Is a Good Candidate for Medial Branch Nerve Block?
- Individuals with persistent back or neck pain unresponsive to conservative treatments.
- Patients whose diagnostic scans or physical exams suggest facet joint involvement.
- Those who may be candidates for radiofrequency ablation if the nerve block confirms the source of pain.
Clinical Research
- Studies demonstrate that medial branch blocks are highly effective for diagnosing the true source of facet-related spine pain.
- Temporary pain relief from the procedure helps predict patients who will benefit from longer-lasting radiofrequency ablation, which can result in 6–12 months or more of pain control.
- Risks are minimal, with mild, short-term side effects such as soreness at the injection site or temporary numbness.
What to Expect
Before, During and After the Procedure
- Before: Patients receive a detailed assessment and instructions. Blood thinners may be paused.
- During: The procedure takes 20–30 minutes. Patients lie face-down; the injection site is cleaned, numbed, and the needle is placed under X-ray guidance. Medication is injected, and pain response is monitored.
- After: Most individuals return home within an hour. Activity restrictions are minimal. Pain relief, if significant, often confirms the facet source, and radiofrequency ablation may be considered next.
Outcomes
- Immediate (but usually temporary) relief of back/neck pain if the facet joint is the root cause.
- Enables precise targeting of follow-up treatments to extend pain relief.
- Improved mobility and participation in physical therapy.
Alternatives and Complementary Treatments
- Epidural steroid injections: Target nerve root or radiating pain rather than localized joint pain.
- Physical therapy, chiropractic care, anti-inflammatory medications, and bracing.
- Radiofrequency ablation: Common next step if significant relief is obtained from the nerve block, for longer-lasting effects.
- Holistic approaches: At Holistiq, options like anti-inflammatory nutrition, chiropractic/manual therapy, and movement rehabilitation are part of a full integrative recovery plan.

FAQs About Medial Branch Nerve Blocks
What is a medial branch nerve block, and how does it work?
A medial branch nerve block involves injecting a local anesthetic—sometimes with a steroid—near the small medial branch nerves that transmit pain from the spine’s facet joints to the brain. This temporarily blocks the pain signals and helps both diagnose and sometimes relieve source-specific spinal pain.
Why are medial branch blocks performed—what’s the goal?
Primarily, they serve as a diagnostic tool to confirm whether the facet joints are the source of your back or neck pain. If significant pain relief follows, more permanent treatments like radiofrequency ablation (RFA) may be considered.
How long does pain relief last after the injection?
Since medial branch blocks are diagnostic, their pain relief is temporary. Typically, relief lasts from a few hours—up to several days if steroids are used.
Why are two blocks (double diagnostic blocks) often used?
To reduce false positives and increase diagnostic accuracy, most protocols require two separate blocks using different anesthetic agents (e.g., lidocaine and bupivacaine). Consistent pain relief across both confirms the facet joints as true pain generators.
What happens if the block provides relief?
If your pain decreases significantly—usually defined as 50–80% relief—you may be a candidate for Radiofrequency Ablation (RFA), a procedure that deactivates the medial branch nerves for longer-term pain relief.
What are the risks or side effects of a medial branch block?
While generally safe, possible risks include:
- Mild side effects like soreness or bruising at the injection site.
- Less common complications such as infection, bleeding, or nerve irritation.
- Very rare but serious risks include allergic or contrast dye reactions.
