Medial Branch Radiofrequency Ablation

What is Medial Branch Radiofrequency Ablation (RFA)?

A medial branch radiofrequency ablation (RFA) is an injection that uses a specialized needle to generate heat to destroy the nerve tissue that transmits pain from a joint.

What are the benefits of Medial Branch Radiofrequency Ablation?

This minimally invasive treatment is used to obtain long term pain relief from a painful joint (facet joint), after that pain source has been confirmed by diagnostic medial branch block [link].

Common Indications:
– Neck pain
– Mid back pain
– Low back pain
– Decrease range of motion in the neck or low back

How does Medial Branch Radiofrequency Ablation work?

Radiofrequency ablations work by delivering a small electrical current that generates heat, interrupting the nerve signal of pain. This reduces the incoming pain signal from the joint.

How to prepare for Medial Branch Radiofrequency Ablation?

The first step to determine your eligibility to receive a radiofrequency ablation is to perform a thorough physical examination and carefully consider your medical and family history.

-Blood thinners (e.g., aspirin, Plavix, Eliquis, warfarin):
You will NOT need to stop them before the procedure
– Medical Clearance (if needed)
If you have heart conditions, bleeding disorders, or infections, your provider may require clearance from your primary doctor or specialist.

What to expect after the procedure?

Radiofrequency ablations are usually performed in under 30 minutes with the patient’s ability to go home the same day after a short recovery period.

There may be some discomfort and stiffness at the site, which typically improves with rest and ice. We recommend our patients go home and relax, however activity as tolerated will not undo the procedure. You may temporarily experience pain similar to a sunburn and slight numbness in the treated area. After the inflammation from the procedure calms down (typically 5-7 days), patients can expect relief anywhere from six months to a year. Despite being destroyed, the nerve does regenerate; the procedure can be repeated if pain returns.
