There is a particular kind of chronic pain that patients with facet joint disease describe — a deep, aching stiffness in the spine that is worst in the morning, sharpens with any twisting or extension movement, and never turns off. It is the pain of arthritis of the spine: the medial branch nerves transmitting pain signals from worn, inflamed facet joints straight to your brain, day after day. Traditional interventions like physical therapy, chiropractic care, and even cortisone injections can reduce this pain temporarily. But for patients with confirmed facet joint syndrome, radiofrequency ablation in Mesa, AZ offers something categorically different: an RFA treatment that targets and interrupts the specific medial branch nerve pathway transmitting pain — sometimes called rhizotomy — delivering long-term pain relief that typically lasts 9-18 months or longer.

What Is Radiofrequency Ablation?

Radiofrequency ablation — also called radiofrequency neurotomy, facet joint ablation, or rhizotomy — is an image-guided interventional procedure in which a physician uses controlled thermal energy from a radiofrequency electrical current to heat a small, precise segment of the medial branch nerve tissue responsible for transmitting pain signals from a diseased facet joint to the brain. By creating a targeted thermal lesion at the nerve, RFA treatment effectively interrupts the pain signal at the source without affecting motor function or surrounding tissue.

Unlike injected steroids — which reduce inflammation around a nerve temporarily — RFA changes the structure of the nerve itself using thermal energy, producing long-term pain relief that outlasts any cortisone injection by months.

Clinical Benefits of Radiofrequency Ablation

• Long-term pain relief lasting 9-18 months or longer — far more durable than steroid injections for facet joint syndrome
• Targets confirmed pain source with precision — thermal energy delivered to the exact medial branch nerves responsible for your symptoms
• Non-surgical outpatient procedure — no hospital stay required
• Restores capacity for physical therapy, exercise, and daily living activities
• Repeatable as medial branch nerves slowly regenerate — subsequent rhizotomy procedures are equally effective
• Dramatically reduces or eliminates daily oral pain medication requirements
• Covered by Medicare and most commercial insurance following positive diagnostic nerve blocks

The RFA Procedure: Step by Step

Diagnostic Confirmation First

RFA treatment for chronic neck pain or back pain is not performed without prior diagnostic confirmation. Before scheduling facet joint ablation, your physician administers medial branch nerve blocks — targeted anesthetic injections that temporarily numb the specific nerve branches supplying the suspected facet joints. Patients who achieve 80% or greater temporary relief from these diagnostic blocks are confirmed as excellent RFA candidates. This step eliminates guesswork and ensures the rhizotomy targets the actual pain generator.

Day of Procedure

You lie on a fluoroscopy table in our procedure suite. The target area is prepped with antiseptic. Local anesthetic is carefully applied along the needle path. Under continuous fluoroscopic imaging, a radiofrequency cannula is advanced to the precise anatomical position alongside the targeted medial branch nerve. Placement is confirmed with both imaging and electrophysiological testing before thermal energy is applied.

Thermal Ablation of the Medial Branch Nerve

The radiofrequency generator delivers thermal energy, heating the needle tip to approximately 80 degrees Celsius for 60-90 seconds, creating a controlled thermal lesion that disrupts pain signal transmission through that nerve branch. Multiple medial branch nerves at multiple facet levels can be treated in the same session based on your diagnostic block results. The controlled thermal energy application is precise — surrounding motor nerve roots are confirmed safe by electrophysiological testing before ablation.

Recovery

Most patients go home within 30-60 minutes. Expect 1-3 weeks of post-procedural soreness as the treated nerve heals — this is normal and resolves before the full benefit takes effect. Most patients begin noticing substantial long-term pain relief by weeks 3-6 following the procedure.

Am I a Good Candidate for RFA in Mesa AZ?

Radiofrequency ablation for chronic neck pain, facet joint syndrome, or low back pain from arthritis of the spine may be right for you if:

• You have chronic neck, mid-back, or low back pain with facet joint syndrome that worsens with spinal extension or rotation for 3 or more months
• Imaging confirms facet joint arthrosis or degeneration consistent with arthritis of the spine at the symptomatic levels
• You have sacroiliac (SI) joint dysfunction causing buttock, hip, or lower back pain confirmed by provocation testing
• You achieved significant temporary relief from prior diagnostic medial branch nerve blocks
• Prior injections provided only short-term benefit and chronic neck pain or back pain has returned
• You want durable, long-term pain relief without surgery or ongoing daily pain medications
