Medial Branch Block — Naples, FL

A medial branch block is a diagnostic injection that numbs the small nerves supplying the facet joints to determine if they are the source of your back or neck pain.

About This Procedure

The medial branch nerves carry pain signals from the facet joints. By temporarily blocking these nerves with local anesthetic, Dr. Kerschner can determine whether the facet joints are causing your pain.

If the block provides significant temporary relief, it confirms the diagnosis and indicates that radiofrequency neurotomy may provide long-lasting relief.

The procedure is performed under fluoroscopic guidance and typically takes 15–20 minutes.

Benefits

• Precisely diagnoses facet joint pain
• Quick and minimally invasive
• Guides treatment decisions for long-term relief
• Can be performed on the cervical, thoracic, or lumbar spine
