Radiofrequency Ablation (RFA) | Spine & Pain CT

What is Radiofrequency Ablation?

Radiofrequency ablation (RFA), also known as radiofrequency neurotomy, is a minimally invasive procedure that uses heat generated by radio waves to target specific nerves and temporarily interrupt their ability to transmit pain signals.

Unlike injections that provide temporary relief, RFA can provide pain relief lasting 6 months to 2 years or more. When the nerves regenerate, the procedure can be repeated with similar effectiveness.

Conditions Treated

Facet Joint Pain

The most common use—treating pain from arthritic facet joints in the neck or lower back.

Sacroiliac Joint Pain

SI joint dysfunction causing lower back and buttock pain.

Chronic Back Pain

Persistent back pain that has responded to diagnostic nerve blocks.

Chronic Neck Pain

Cervical facet joint pain causing neck stiffness and headaches.

The RFA Procedure

1

Preparation

You'll lie on a procedure table. The area is cleaned and numbed with local anesthetic. Light sedation is available.

2

Needle Placement

Using fluoroscopic (X-ray) guidance, a specialized needle is positioned precisely near the target nerve.

3

Testing

Sensory and motor stimulation tests confirm proper needle placement before treatment.

4

Ablation

Radiofrequency energy heats the nerve, creating a lesion that interrupts pain signal transmission.

Benefits of RFA

Long-lasting relief (6-24 months)

Minimally invasive outpatient procedure

Can significantly reduce medication use

Can be repeated when pain returns

Most patients return to activities quickly

Usually covered by insurance

Are You a Candidate for RFA?

RFA may be right for you if:

You've had good relief from diagnostic nerve blocks

You have chronic facet or SI joint pain

Steroid injections provided temporary relief

You want to reduce reliance on pain medications
