Cervical Radiofrequency Ablation (RFA) for Facet-Mediated Neck Pain

Cervical radiofrequency ablation is used for selected patients with chronic axial neck pain arising from the cervical facet joints. The procedure targets the medial branch nerves that carry pain signals from those joints.

Cervical RFA is not designed to treat cervical radiculopathy itself. Arm pain, numbness, tingling, or weakness from spinal nerve-root irritation requires a separate evaluation and may lead to treatments such as a cervical epidural steroid injection or other care depending on the diagnosis.

Why Medial Branch Blocks Come First

Patients generally undergo diagnostic cervical medial branch blocks (MBB) before RFA. Temporary relief that is consistent with the expected local-anesthetic effect helps determine whether the facet joints are a significant source of pain. Confirmatory blocks may be required before RFA depending on the clinical plan and insurance criteria.

How the Procedure Is Performed

Using fluoroscopic guidance, the physician positions radiofrequency cannulas near the selected cervical medial branch nerves. Appropriate sensory/motor testing and local anesthesia are used as clinically indicated. Controlled radiofrequency energy is then applied to create a small thermal lesion at each target.

Recovery and Expected Results

Temporary post-procedure soreness, muscle spasm, numbness, or neuritic discomfort can occur. When RFA is successful, relief may last for months, but the degree and duration of benefit vary and cannot be guaranteed. Nerve function can recover over time, and pain may recur.

Potential Risks

Potential risks include bleeding, infection, medication reaction, temporary numbness or weakness, neuritis, injury to nearby structures, incomplete pain relief, and rare neurologic complications. These are reviewed before treatment.

Persistent pain after prior cervical spine surgery requires individualized evaluation; cervical medial branch RFA is considered only when facet-mediated pain is supported
