Cervical & Lumbar Radiofrequency Ablation
Facet-pain treatment after successful diagnostic blocks
Medial branch radiofrequency ablation uses controlled heat to interrupt selected nerve signals from painful cervical or lumbar facet joints.
This guide is educational and cannot determine candidacy. Every treatment has limitations and risks, and outcomes are not guaranteed. A clinician must review your diagnosis, health history, imaging, medicines, and goals.
What it targets
A procedure built for a particular pain mechanism.
Small medial branch nerves carry sensation from the facet joints. When a carefully performed diagnostic block produces substantial temporary relief, controlled radiofrequency energy can create a lesion on the same nerve. The nerve may recover over time, so benefit—when achieved—is not necessarily permanent.
Who may be evaluated
Candidacy begins with diagnostic fit.
RFA is best understood as the treatment stage of a diagnostic pathway, not as a first visit procedure for nonspecific neck or back pain.
Clinical considerations
- Predominantly axial neck or low-back pain rather than untreated radicular pain
- Examination and imaging that support facet-mediated pain and exclude stronger alternatives
- Persistent symptoms despite a reasonable trial of conservative care
- Substantial, reproducible relief from one or more diagnostic medial branch blocks according to payer criteria
- No active infection, uncontrolled bleeding risk, or other procedure contraindication
Evaluation may include
- Focused history and examination for facet loading and competing pain patterns
- Imaging review to assess degeneration and rule out another primary diagnosis
- Fluoroscopy-guided medial branch block or blocks using local anesthetic
- Pain diary and functional comparison during the expected anesthetic window
How it is performed
The procedure, step by step.
Confirm the target
Only nerves associated with joints that responded convincingly to diagnostic blocks are selected.
Position the cannula
Under X-ray guidance, specialized needles are placed along the targeted medial branch nerves; sensory and motor testing may be used.
Create controlled lesions
Local anesthetic is given and radiofrequency energy heats a small treatment zone before the needles are removed.
After the procedure
Recovery, follow-up, and important risks.
Recovery & follow-up
- Temporary soreness, muscle spasm, sunburn-like sensitivity, or numbness can occur.
- Many patients return to light activity quickly, but the specific plan depends on the treated region and sedation.
- Relief may take several days or weeks as post-procedure irritation settles.
- Rehabilitation often resumes to build strength and movement confidence while pain is reduced.
Risks & limitations
- Bleeding, infection, local pain flare, numbness, or neuritis
- Rare injury to a nearby nerve or other structure
- Incomplete benefit despite positive diagnostic blocks
- Nerve regeneration and recurrence that may lead to reassessment or repeat treatment

Evidence & technology
What is established—and what is still being studied.
Evidence in context
Specialty guidelines and coverage policies support cervical and lumbar medial branch RFA when diagnostic criteria are met. The quality of target confirmation and technique strongly influences how research applies to an individual patient.
Brands are examples, not endorsements
Multiple radiofrequency generators, electrodes, and cannulas can perform the procedure. The therapeutic concept is not proprietary to one manufacturer.
