Did you know? 62% of patients found significant relief at 2 weeks, with lumbar blocks lasting 6+ months.
When back or neck pain persists despite other treatments, identifying the exact source becomes critical. Medial branch blocks serve a dual purpose: pinpointing whether facet joints are causing your pain and providing temporary relief.
The Evidence Behind Medial Branch Blocks
Cervical medial branch blocks achieved 62.2% clinically significant pain reduction at 2 weeks, declining to 22.7% at 3 months. This demonstrates valuable diagnostic and short-term therapeutic benefit.
Lumbar medial branch blocks showed even more promising results. Therapeutic benefits lasted at least 6 months post-injection with statistically significant improvements in both physical and emotional functioning.
Who Benefits from This Procedure?
• Patients with suspected facet joint-mediated pain in the cervical, thoracic, or lumbar spine
• Those requiring diagnostic confirmation before considering radiofrequency ablation
• Individuals seeking temporary relief from facet joint arthritis or spinal osteoarthritis
• Candidates who achieve greater than 50% pain relief qualify for longer-lasting radiofrequency treatment
What to Expect
Medial branch blocks are performed as outpatient procedures using fluoroscopic guidance to ensure precise placement of local anesthetic at the medial branch nerve locations. Multiple spinal levels may be blocked during a single session. The procedure helps determine if facet joints are your pain source while providing temporary relief.
