Cervical Medial Branch Cooled Radiofrequency Ablation
If you have been living with chronic neck or shoulder pain for a long time — tried medication, tried physiotherapy, and still the pain keeps coming back — Cervical Medial Branch Cooled Radiofrequency Ablation (Cooled RFA) is the most advanced interventional technology currently available for breaking that cycle, delivering effective and long-lasting relief.
Understanding the Two Types of Neck Pain
- Localised neck pain — pain concentrated in the neck itself, or referring into the shoulder blade, without travelling down the arm. This type originates from degeneration of the cervical facet joints and is the pattern that responds most effectively to Cooled RFA.
- Radicular neck pain — pain, tingling, or numbness that radiates down the arm along a nerve pathway. This pattern suggests compression of a major nerve root rather than facet joint pathology, and is generally better suited to epidural steroid injection rather than RFA.
Accurate diagnosis is essential — Cooled RFA is highly effective for facet-mediated pain but is not the appropriate treatment for radicular symptoms.
What Is Cooled RFA — and Why Does It Outperform Conventional RFA?
Cooled Radiofrequency Ablation (Cooled RFA) is a non-surgical pain procedure that uses radiofrequency energy to generate targeted heat, deactivating the medial branch nerve fibres that transmit pain signals from the cervical facet joints to the brain.
What Makes the Cooled Technology Different
- Larger, more precise treatment zone — conventional RFA needles heat the tissue immediately surrounding the tip, which creates a relatively small ablation area. Cooled RFA uses an internal water-cooling system within the needle that actively manages tip temperature, preventing overheating. This allows significantly more radiofrequency energy to be delivered safely, creating a larger and more spherical treatment zone. The result is better coverage of the target nerve — particularly important at the cervical level where nerve anatomy can vary between individuals.
- Internationally certified technology — Cooled RFA is FDA-approved in both Thailand and the United States and is used as the standard of care in leading pain management centres worldwide.
Who Is Cooled RFA Suitable For?
- Patients with chronic neck or shoulder pain confirmed to originate from cervical facet joint degeneration
- Patients who have undergone a cervical medial branch block and experienced significant pain relief, confirming that the facet joints are the pain source and that ablation is likely to be effective
- Patients seeking long-lasting treatment outcomes with reduced reliance on ongoing pain medication
The Procedure (Approximately 45–60 Minutes)
This is a safe, precise, minimally invasive procedure performed under local anaesthesia.
General anaesthesia is not required. Total procedure time is approximately 45–60 minutes, .
depending on the number of spinal levels being treated.
- Positioning and sedation — the patient lies on their back in a comfortable, relaxed position. An anaesthesiologist administers a mild anxiolytic or sedative to ensure the patient remains calm and comfortable throughout
- Real-time image guidance — the physician uses ultrasound or fluoroscopy (live X-ray) to visualise and accurately locate the target medial branch nerve at each cervical level in real time
- Cooled ablation — a specialised cooled probe needle is advanced to the target nerve position; radiofrequency energy is then delivered through the water-cooled system to deactivate the nerve fibres transmitting pain, creating a wider lesion than conventional RFA without risk of thermal injury to surrounding tissue
Expected Outcomes
- Long-lasting pain relief — most patients experience sustained reduction in pain lasting from several months to over 12 months, with some achieving longer-term relief
- Restored quality of life and neck mobility — reduced pain allows patients to move their neck more freely and return to work, exercise, and daily activities more comfortably
- Reduced medication dependence — Cooled RFA helps patients significantly reduce or eliminate the need for ongoing pain medication, lowering the cumulative risk of long-term analgesic use on liver and kidney function
- Post-Procedure Care
- Travel safety : Do not drive on the day of the procedure. Arrange for someone to collect you, or use public transport.
- Rest : Rest adequately for the first 24 hours and avoid strenuous activity or heavy lifting.
- Injection site : Mild soreness, stiffness, or tightness at the treatment site is normal and typically resolves within 1–7 days. This is a normal tissue response, not a return of the original pain.
