Quick Insights

Radiofrequency ablation (RFA) uses controlled heat to interrupt nerve signals from facet joints that contribute to leg pain. Unlike steroid injections that temporarily reduce inflammation, RFA targets the nerves themselves. Research shows this approach can provide meaningful relief when pain originates from facet joints rather than disc herniation. Proper diagnosis through imaging and diagnostic blocks determines whether someone is an appropriate candidate for this image-guided procedure.

Key Takeaways

• Recent systematic reviews show RFA provides statistically significant improvements in pain and function for facet-mediated leg pain.
• Relief typically lasts 6-12 months, often longer than steroid injections, though nerves can regenerate over time.
• Best outcomes occur in patients whose diagnostic facet blocks confirm the pain source before ablation.
• The outpatient procedure uses fluoroscopic guidance to ensure precise nerve targeting with favorable safety profiles.

Why It Matters

When injections stop working after a few weeks, the cycle of temporary relief becomes exhausting. RFA offers a different mechanism that may help you stand long enough to finish projects, walk without constant leg pain, or sleep through the night. Understanding whether your pain comes from facet joints—not just hoping another treatment works—gives you confidence in your next step rather than fear of wasting more time.

Radiofrequency ablation for sciatica treatment works differently than steroid injections—it interrupts nerve signals from facet joints rather than temporarily reducing inflammation. Recent systematic reviews show this approach provides statistically significant improvements in pain and function when your leg pain stems from facet joints rather than disc herniation alone.

The key is accurate diagnosis before treatment. In my practice at Napa Valley Orthopaedic Medical Group, I use imaging and diagnostic blocks to pinpoint whether your pain originates from facet joints—because RFA only works when we're targeting the right source. Whether you're in Yountville, St. Helena, or American Canyon, relief typically lasts six to twelve months, often longer than injections, giving you time to stand through projects and walk without constant leg pain.

How RFA Targets Facet and Nerve-Related Pain in Napa

Radiofrequency ablation works by using controlled heat to interrupt nerve signals from facet joints in your spine.

These small joints connect your vertebrae and can become a significant source of both back and leg pain. When facet joints develop arthritis or inflammation, they send pain signals through tiny nerves called medial branch nerves.

Here's what makes RFA different from injections: steroid injections temporarily reduce inflammation around irritated structures. The relief often lasts weeks to a few months as the medication wears off.

RFA takes a different approach. Clinical trials demonstrate that radiofrequency denervation heats these medial branch nerves to about 80 degrees Celsius, creating a controlled lesion that stops them from transmitting pain signals.

Not all sciatica comes from disc herniation pressing on nerve roots. In my Napa practice, I frequently see patients whose leg pain actually originates from facet joints referring pain down the leg—a pattern called facet-mediated radicular pain.

Your facet joints can send pain signals that travel down your buttock and leg, mimicking classic sciatica symptoms. This is why accurate diagnosis matters so much before considering any treatment.

The heat from RFA doesn't damage surrounding tissue or bone. I use fluoroscopic imaging throughout the procedure to position the radiofrequency probe precisely next to the target nerves.

This image guidance ensures we're treating the exact nerves responsible for your pain pattern.

Who Benefits Most from Radiofrequency Ablation in Napa

RFA works best for patients whose pain comes from facet joints, confirmed through diagnostic testing.

This is the most important factor in determining whether you're an appropriate candidate. I can't emphasize enough that RFA isn't effective for everyone—it requires accurate diagnosis of your specific pain source.

In my practice, I use a systematic evaluation process before recommending RFA. First, I review your imaging studies to look for facet joint arthritis or other structural changes that might explain your symptoms.

During your physical exam, I assess specific movement patterns and pain locations that suggest facet involvement. But imaging and exam findings alone aren't enough.

The diagnostic step that determines candidacy is called a medial branch block. I perform these image-guided injections to temporarily numb the nerves supplying your facet joints.

If you experience significant pain relief—typically 75% or greater reduction—for several hours after the block, it confirms your facet joints are the pain source. Research demonstrates that patient selection through diagnostic blocks is essential for identifying who will benefit from RFA.

You might be a good candidate if you've had brief relief from facet injections but the benefit wore off after a few weeks. This pattern suggests your facet joints are indeed the problem, but you need a longer-lasting solution than repeated steroid injections.

I also consider patients appropriate when they have pain with specific movements—like twisting, bending backward, or standing for extended periods—that typically indicate facet involvement.

Clinical evidence shows variability in outcomes depending on careful candidate evaluation, which is why I don't recommend RFA without this diagnostic confirmation.

RFA isn't appropriate for everyone with leg pain. If your symptoms come primarily from disc herniation compressing a nerve root, or from spinal stenosis narrowing the spinal canal, RFA likely won't address your pain source.

This is exactly why the diagnostic process matters—it prevents you from undergoing a procedure that won't help your specific problem.

What to Expect: The RFA Procedure and Recovery

The RFA procedure is performed as an outpatient treatment at our Napa clinic, typically taking 30 to 60 minutes.

You'll be awake during the procedure, though we provide medication to help you relax. I use local anesthesia to numb the skin and deeper tissues where I'll place the needles.

Throughout the procedure, I use fluoroscopic imaging—essentially real-time X-ray guidance—to visualize your spine and position the radiofrequency probe precisely next to the target nerves. This image guidance is critical for both safety and effectiveness.

Once the probe is positioned correctly, I test the placement by sending a small electrical current through it. You'll feel a tingling sensation in the area where your pain typically occurs, confirming we're targeting the right nerves.

After confirming placement, I inject additional local anesthetic around the nerve before applying the radiofrequency energy. The heat application itself takes about 90 seconds per nerve.

Most patients describe feeling warmth or pressure during this phase, but the local anesthetic minimizes discomfort.

You can typically go home within an hour after the procedure. Plan to have someone drive you, as the relaxation medication affects your ability to drive safely.

Recovery follows a predictable pattern in most patients. You might experience increased soreness at the needle sites for a few days—this is normal and responds well to ice and over-the-counter pain medication.

I recommend resuming light activities within a day or two, avoiding heavy lifting or strenuous exercise for about a week. Most patients return to full activities within one to two weeks.

Here's what surprises many patients: relief doesn't happen immediately. The nerves need time to stop sending pain signals as the lesion develops.

You might not notice significant improvement for one to three weeks after the procedure. Systematic reviews of nerve ablation techniques confirm favorable safety profiles when performed with proper image guidance.

My expertise in image-guided procedures ensures precise needle placement, which directly affects both safety and outcomes. I've performed hundreds of these procedures and understand the subtle anatomical variations that require adjustment in technique.

Comparing RFA to Steroid Injections for Lasting Relief

This comparison directly addresses what you're experiencing—injections that help briefly but don't provide the duration you need.

Steroid injections work by reducing inflammation around irritated structures in your spine. The medication bathes the area, temporarily calming the inflammatory response that contributes to pain.

For facet joints specifically, the steroid reduces inflammation in and around the joint capsule. This approach can provide meaningful relief, but the medication gradually gets absorbed and metabolized by your body.

Most patients experience benefit for a few weeks to a few months before pain returns to baseline levels.

RFA takes a fundamentally different approach. Instead of temporarily reducing inflammation, it interrupts the nerve signals themselves by creating a controlled lesion on the medial branch nerves.

These nerves can't transmit pain signals after successful ablation. The relief typically lasts six to twelve months, sometimes longer, because the nerves need time to regenerate.

Meta-analyses comparing radiofrequency denervation to facet steroid injections show RFA often provides superior duration of relief in appropriately selected patients. This doesn't mean RFA is always better—it means that when your pain comes from facet joints, RFA may offer the longer relief you're seeking.

Neither approach is permanent. Steroid injections wear off as the medication is absorbed.

RFA lasts longer, but the ablated nerves can regenerate over time, allowing pain signals to return. When this happens, repeat RFA procedures are possible and often effective.

Individual results vary based on several factors. Your specific pain source matters most—RFA only works when facet joints are the primary pain generator.

Other factors include the extent of facet joint arthritis, whether you have pain from multiple spinal levels, and how your body responds to the procedure.

In my practice, I've observed that patients who had clear, temporary relief from diagnostic facet blocks tend to have the most predictable outcomes with RFA. This pattern makes sense—if blocking the nerves temporarily eliminated your pain, ablating those same nerves should provide longer-lasting relief.

The goal isn't to eliminate all pain forever. The goal is to reduce your pain enough that you can stand through projects, walk without constant leg discomfort, and sleep through the night.

RFA offers a different mechanism than repeated injections, potentially giving you the duration of relief that makes daily activities manageable again.

If facet joint dysfunction is a source of your discomfort, our practice also provides chronic pain treatment options that complement interventional procedures to address ongoing symptoms more comprehensively.

One Patient's Experience

As a pain physician, I see how much courage it takes to try another treatment after injections stop working.

Dawn has been a patient of mine for several years now, managing her low back pain through various approaches. She came to me after realizing her insurance plan wasn't providing the comprehensive interventional options she needed for lasting relief.

"Dr. Weisbein has been treating me for my Low Back Pain for quite a few years now. I am a Kaiser Member but have realized that Kaiser doesn't really do very much unless you need surgery. Dr. Weisbein has been a GODSEND!. Without her, I am not sure what I would be doing. She is kind and listens to you. She really understands pain. Thank you so much for taking such good care of me."

Frequently Asked Questions

How long does it take to feel relief after radiofrequency ablation?

Relief doesn't happen immediately after RFA. The ablated nerves need one to three weeks to stop transmitting pain signals as the lesion develops. Most patients notice gradual improvement during this period. You might experience temporary soreness at needle sites for a few days, which is normal. Once relief begins, it typically lasts six to twelve months, sometimes longer. This timeline differs significantly from steroid injections, which may provide faster but shorter-lasting relief.

Will my insurance cover radiofrequency ablation for sciatica?

Insurance coverage for RFA typically requires documentation of failed conservative treatments and positive diagnostic facet blocks. Most plans cover the procedure when medical necessity is established through this diagnostic process. I work with patients to navigate prior authorization requirements, which usually include imaging studies showing facet joint involvement and documented response to diagnostic injections. Coverage policies vary by insurer, so I recommend scheduling a consultation to review your specific plan's requirements before proceeding.

What happens if RFA doesn't provide adequate relief?

Failed RFA doesn't mean you're out of options. If the procedure doesn't provide meaningful improvement, we reassess your pain source—sometimes the diagnosis needs refinement. I offer other interventional approaches including spinal cord stimulation for nerve-related pain, targeted nerve blocks for different pain generators, or surgical evaluation if structural issues require correction. My practice focuses on comprehensive pain management, so we work together to find the approach that addresses your specific pain pattern rather than giving up after one attempt.
