If you’ve had significant relief from medial branch nerve blocks but the pain later returned, your doctor may recommend Radiofrequency Ablation (RFA).
This minimally invasive procedure uses precisely directed heat energy to gently deactivate tiny pain-carrying nerves in the spine offering longer-lasting relief from facet joint arthritis or chronic low-back and neck pain.
If you’ve had significant relief from medial branch nerve blocks but the pain later returned, your doctor may recommend Radiofrequency Ablation (RFA).
This minimally invasive procedure uses precisely directed heat energy to gently deactivate tiny pain-carrying nerves in the spine offering longer-lasting relief from facet joint arthritis or chronic low-back and neck pain.
Facet joints can become painful from arthritis or degeneration. The medial branch nerves that transmit these pain
signals can be safely and temporarily interrupted using RFA.
RFA is most often recommended for:
Confirmed facet joint pain following successful diagnostic nerve blocks
Chronic back or neck pain that worsens when standing or twisting
Patients seeking to avoid long-term medication or repeated injections

Preparation – The procedure is performed in a sterile, outpatient setting under fluoroscopic (X-ray) guidance. Local anesthesia is used to numb the skin.
Needle Placement – Thin specialized needles are positioned precisely near the targeted medial branch nerves.
Testing – Mild stimulation confirms the correct nerve location.
Ablation – Radiofrequency energy gently heats the nerve for 60–90 seconds, interrupting its ability to carry pain signals.

The procedure typically takes 30–45 minutes, and patients return home the same day.
Temporary soreness or muscle tightness for a few days
Gradual onset of pain relief over 1–3 weeks
Full benefit often realized within one month
Relief can last 6–12 months, sometimes longer, until nerves naturally regenerate
Normal activities may resume within a day, though heavy exertion should wait 48 hours.
Radiofrequency ablation is extremely safe when performed under image guidance.
Potential—though rare—effects include:
Temporary numbness or localized burning sensation
Mild swelling or bruising at needle sites
Rare infection or nerve irritation
Because the targeted nerves only carry pain signals (not strength or movement), there’s no
risk of paralysis or muscle weakness.
Answer: Blocks test the pain source; ablation stops the nerve signal.
A medial branch block temporarily numbs a spinal joint to confirm the pain generator. If it works, radiofrequency ablation (RFA) uses heat to deactivate that small nerve for 6–12 months. The joint stays stable, and pain often lessens dramatically.
Lumbar | Interventional Spine | RFA
Answer: Relief often lasts 6–12 months and the procedure can be repeated safely.
After an RFA, the tiny sensory nerves that send pain signals grow back slowly. Many patients enjoy meaningful relief for 6 months to a year. If the pain returns, a repeat ablation can usually be performed using the same approach. Regular stretching and strengthening help extend the benefit. Lumbar | Cervical | Interventional Spine | RFA
Answer: It’s usually from facet-joint stress or weak postural muscles.
Sitting flexes the lumbar spine and compresses facet joints and discs, especially if the core is de-conditioned. Over time, this posture leads to inflammation and stiffness. Supportive cushions, regular breaks, and targeted therapy for core and glute muscles often relieve symptoms.
Lumbar | Ergonomics | Rehab
Answer: It injects dye into spinal discs to find the pain source but carries risks.
Discography involves pressurizing discs with contrast dye while monitoring pain response. It was once common before spine surgery but is now less used because it can worsen disc damage and cause infection. Modern MRI and targeted nerve blocks provide safer diagnostic insight.
Answer: Adjacent levels often wear out faster.
Spinal fusion stabilizes one level but transfers stress to the discs and joints above and below, leading to adjacent segment disease. Scar tissue, muscle atrophy, and nerve irritation can also persist. Nonsurgical options like PRP or radiofrequency treatment can help preserve the surrounding spine.
Lumbar | Post-Surgery | Interventional Spine
Answer: They mean nearby levels or implants break down over time.
After fusion, joints next to the fused area compensate by moving more, sometimes developing arthritis or stress fractures. Hardware fatigue or loosening can also occur years later. Regular imaging helps detect changes early; pain-management injections or strengthening programs can often delay revision surgery.
Lumbar | Cervical | Post-Surgery | Spine Degeneration
Answer: Back-related pain travels below the knee; joint pain usually stays local.
Nerve compression in the spine typically causes sharp, shooting pain that radiates past the knee or into the foot. Hip or knee arthritis usually creates aching localized pain or stiffness without tingling. Imaging and physical-exam maneuvers help determine whether the source is spinal, joint, or both.
Diagnostics | Lumbar | Hip | Knee
Answer: It delivers anti-inflammatory medicine around pinched nerves.
Guided by X-ray, a thin needle places medication into the epidural space of the spine. The steroid reduces swelling around irritated nerves from a herniated disc or arthritis. Relief may last weeks to months and can allow better participation in physical therapy.
Interventional Spine | Epidural | Lumbar | Cervical
Answer: Fever, unexplained weight loss, numbness, or bladder issues.
Warning signs include constant pain at rest, night sweats, progressive weakness, loss of control of urine or stool, or recent infection. These could signal infection, tumor, or severe nerve compression and need emergency evaluation.
Safety | Lumbar | Cervical | Emergency
Answer: Only after conservative care has clearly failed and red flags are excluded.
Most mechanical back or neck pain improves with guided injections, therapy, or biologic repair within 3–6 months. Surgery is reserved for progressive weakness, structural instability, or nerve compression causing loss of function. A second opinion is always appropriate before proceeding.
Lumbar | Cervical | Surgery Decision
Answer: It’s a small stabilizing joint behind each vertebra that can become arthritic.
Facet joints allow bending and twisting. With aging or injury, they may develop arthritis and inflammation that causes sharp localized pain, often worse when leaning backward or standing long periods. Facet injections or RFA can calm these joints for months at a time.
Lumbar | Cervical | Anatomy | Interventional Spine
Answer: Sudden weakness, numbness, fever, or bladder/bowel changes.
Go to the ER immediately for severe pain with loss of strength, incontinence, high fever, or trauma with head injury. These could indicate nerve or spinal-cord compression, infection, or fracture. Early treatment prevents permanent damage.
Cervical | Lumbar | Emergency | Safety
Answer: A nerve-root block targets one specific nerve, while an epidural bathes several.
A selective nerve-root block (SNRB) uses live X-ray to deliver medication directly around one irritated spinal nerve. It helps confirm which nerve causes the pain and can calm inflammation at that precise level. Epidural injections are broader, covering multiple nerves at once.
Answer: Hip arthritis hurts in the groin; back problems radiate to the leg.
Hip joint disease often causes deep aching in the groin or front thigh, worse with walking or stairs. Lumbar nerve compression tends to cause burning or tingling down the leg. Diagnostic injections into the hip or spine can confirm the true source.
Hip | Lumbar | Diagnostics | Joint Pain
Answer: Yes, but injections are placed around not into the fused levels.
PRP and bone-marrow concentrate can reduce inflammation in joints and ligaments next to a fusion where new pain develops. These procedures don’t interact with the hardware itself. Most patients benefit from improved flexibility and less reliance on pain medication.

If you’ve had temporary relief from facet or medial branch blocks but pain keeps returning, Radiofrequency Ablation may be the next step toward longer-lasting comfort and improved function.
