Established Spine Gold Standard
What is Traditional Radiofrequency Ablation (RFA)?
Radiofrequency Ablation (RFA), also known as rhizotomy, is a proven medical procedure designed to significantly reduce long-lasting back or neck pain. It works by applying controlled thermal heat energy to deactivate tiny sensory pain nerves (the medial branch nerves) near the spine so they can no longer transmit pain alarms to the brain.
Preserves Spine Integrity: RFA does not damage the spinal structure, bones, or intervertebral discs. It selectively affects only the tiny nerve fibers that carry pain signals from inflamed joint surfaces.
Pain Conditions RFA Can Help
RFA is most effective for pain stemming from the facet joints of the spine—joints that enable spinal movement but become painful due to arthritis or degeneration:
- ✓ Chronic low back pain (lumbar facet joint pain)
- ✓ Chronic neck pain (cervical facet joint pain)
- ✓ Chronic mid-back pain (thoracic facet joint pain)
- ✓ Spine pain that worsens with bending, twisting, or prolonged standing
Please Note: RFA is not intended for nerve compression pain (such as sciatica caused by a herniated/slipped disc).
Traditional RFA Highlights
- ✓ Long-Lasting Relief: Typically provides 6 to 18+ months of targeted pain relief.
- ✓ Outpatient Procedure: Completed in 20–45 minutes under light sedation.
- ✓ Guided Safety: Live X-ray (fluoroscopy) and sensory/motor nerve safety testing.
- ✓ Repeatable Option: As nerve fibers slowly regenerate, procedure can be safely repeated.
Mandatory Step
How Do We Know RFA Is Right for You?
Before undergoing Radiofrequency Ablation, patients must have diagnostic Medial Branch Nerve Blocks. This involves temporarily numbing the targeted pain nerves with a local anesthetic test injection. If your pain dramatically improves (>50–80% relief), it confirms those nerves are the precise source of pain, validating RFA eligibility for high treatment success.
How the Traditional RFA Procedure Works
1
Comfort & Local Numbing
You lie comfortably on a procedure table. The skin is cleaned and frozen with local anesthetic while light sedation keeps you completely relaxed.
2
Live Fluoroscopic Guidance
Using live X-ray (fluoroscopy) guidance, the physician places a thin needle electrode precisely adjacent to the target medial branch sensory nerve.
3
Safety Response Testing
Electrical sensory and motor stimulations are performed to verify exact electrode position away from motor nerves controlling muscle movement.
4
Thermal Nerve Deactivation
Controlled radiofrequency thermal heat energy (approx. 80°C) is applied for 60–90 seconds to quiet the nerve's pain transmission capabilities.
What to Expect During Recovery & Relief
Procedure Time
Takes only 20–45 minutes as an outpatient procedure. You return home the same day.
Post-Procedure Feel
Mild pressure during treatment and temporary localized soreness for a few days as tissues heal.
Onset of Pain Relief
Relief is delayed, typically beginning after 1 to 3 weeks once local soreness resolves.
Duration of Relief
Commonly lasts 6 to 18 months. When nerves slowly regrow, the procedure can be safely repeated.
Recovery & Aftercare Instructions
Essential guidelines to ensure a safe, comfortable recovery and long-lasting pain relief after your procedure.
1
Rest for 24 Hours
Take it easy and rest comfortably at home for the first 24 hours following your procedure.
2
Resume Activity
Most patients can safely return to light, normal daily activities starting the next day.
3
Avoid Heavy Lifting
Refrain from strenuous heavy lifting, vigorous exercise, or intense exertion for a few days.
4
Soreness Care
Use ice packs or simple over-the-counter pain relievers as directed for any mild soreness.
5
Rehabilitation
Physical therapy may be recommended once initial soreness subsides to restore full mobility.
Next-Generation Non-Invasive Innovation
Needle-Less High-Intensity Focused Ultrasound (HIFU)
Premier Pain Institute is proud to feature Needle-Less High-Intensity Focused Ultrasound (HIFU)—utilizing the cutting-edge FUSMobile Neurolyser XR platform—to offer patients a breakthrough 100% non-invasive alternative for chronic back pain caused by lumbar facet joint arthritis.
Unlike traditional RFA which requires inserting thin needle electrodes through skin and muscular tissue, HIFU delivers focused acoustic ultrasound energy entirely through the surface of the skin. The ultrasound waves converge precisely at the target medial branch sensory nerves, creating controlled thermal neurotomy without making a single skin puncture or incision.
100% Needle-Free
Zero skin punctures, zero scalpels, and zero probes inserted into your back tissues.
Zero Needle Traumas
Eliminates needle-related risks of bleeding, hematoma, infection, or wound healing.
Superior Comfort
Non-invasive energy transfer ensures high patient comfort and minimal post-treatment downtime.
FDA & Global Clearance
FDA De Novo clearance, Health Canada approval, CE Mark, and UK clearance for lumbar back pain.
FUSMobile HIFU Highlights
- ✓ Non-Invasive Ablation: Thermal nerve desensitization delivered outside the body.
- ✓ X-Ray Fluoroscopy Guidance: Real-time image-guided precision target mapping.
- ✓ Proven Clinical Equivalence: Multi-center trial data confirms long-lasting relief matching standard RFA.
- ✓ No Recovery Restrictions: Immediate resumption of daily routine without needle wound care.
How Does Needle-Less HIFU Work?
HIFU operates on the exact principle of focusing light through a magnifying glass to generate heat at a single point. High-frequency acoustic ultrasound waves pass safely through skin and soft tissue, concentrating exclusively at the focal zone where the medial branch nerve rests against the facet joint.
1
Diagnostic Block Validation
Just like traditional RFA, a preliminary diagnostic nerve block confirms your pain originates from facet joint medial branch nerves.
2
Fluoroscopic Target Mapping
Under live X-ray (fluoroscopy), the physician aligns the external HIFU transducer directly over the lumbar facet joint target.
3
Non-Invasive Acoustic Delivery
Focused ultrasound energy pulses pass harmlessly through skin layer to generate localized thermal neurotomy at the target nerve.
4
No needle wounds to heal or dress. Patients experience rapid post-procedure recovery with long-term back pain relief.

Frequently Asked Questions
Diagnostic Medial Branch Blocks temporarily numb the exact nerves supplying your spinal facet joints. If the test injection provides significant temporary relief (over 50–80%), it proves those specific nerves are responsible for your back pain, ensuring high success rates when we proceed with long-term RFA or HIFU ablation.
Yes! Needle-less HIFU uses High-Intensity Focused Ultrasound energy (FUSMobile Neurolyser XR) delivered through the surface of the skin. Acoustic sound waves pass safely through tissue without any skin punctures, scalpels, or needles inserted into the spine.
No. Both RFA and HIFU target only the tiny sensory medial branch nerve fibers carrying pain alarms from the facet joints. Neither procedure damages the spine bones, spinal cords, surrounding muscles, or intervertebral discs.
Pain relief typically lasts between 6 to 18 months or longer. Sensory nerves slowly regenerate over time. If your back pain returns in the future and the initial treatment was effective, both RFA and HIFU can be safely repeated.
