Cooled Radiofrequency Ablation for Shoulder Joint Nerve Pain (Shoulder Articular Branch Cooled RFA)
If you're dealing with chronic shoulder pain that hasn't responded well to conventional treatments, Cooled Radiofrequency Ablation targeting the articular branches around the shoulder joint is an advanced, non-surgical option that delivers longer-lasting pain relief — and gets you back to living fully.
What Is Shoulder Articular Branch Cooled RFA?
Cooled RFA is a minimally invasive procedure used to treat chronic shoulder pain, particularly pain caused by shoulder joint degeneration (osteoarthritis).
Unlike conventional RFA, which uses heat alone to deactivate pain-transmitting nerves, Cooled RFA incorporates an internal water-cooling system within the probe tip. This allows radiofrequency energy to penetrate more deeply and spread more broadly into surrounding tissue — creating a larger "relief zone" compared to traditional RFA. The result is more comprehensive coverage of the nerves around the shoulder joint that are responsible for sending pain signals to the brain.
Cooled RFA technology is approved by both the US FDA and the Thai FDA (อย.), and is used in leading pain management centers worldwide.
Who Is Cooled RFA Suitable For?
- Chronic shoulder pain from osteoarthritis, rotator cuff tears, or long-standing injury
- Persistent post-surgical pain — patients who have undergone shoulder surgery but still experience significant pain
- Treatment-resistant cases — those who have tried medication, physical therapy, or steroid injections without lasting relief
- Positive responders to a diagnostic nerve block — patients who previously had a local anesthetic injection to the shoulder's articular nerves and experienced clear, meaningful pain reduction
The Procedure
The procedure is safe, precise, and typically takes 45–60 minutes depending on the number of nerves being treated.
- Anesthesia preparation: A local anesthetic is administered along with a mild sedative provided by an anesthesiologist to keep you comfortable throughout the procedure.
- Real-time image guidance: The physician uses both ultrasound and fluoroscopy (live X-ray) simultaneously to pinpoint the exact location of the target nerves with high accuracy.
- Cooled RFA delivery: A small probe is positioned at each nerve site and cooled radiofrequency energy is applied, deactivating the nerves that transmit pain signals from the shoulder to the brain.
Post-Procedure Care and Recovery
- Mild soreness at the treatment site is normal for the first 1–3 days and will gradually resolve on its own.
- Most patients can return to their normal daily routine the following day. Avoid strenuous activity or heavy exercise during the first week to allow complete recovery.
Why Choose Cooled RFA for Shoulder Pain?
Cooled RFA offers several advantages over conventional treatments:
- Longer-lasting relief than steroid injections or standard RFA
- Improved shoulder mobility and function
- Reduced reliance on pain medication
- No surgery required — minimally invasive with a very small entry point
- Allows patients to return to an active, full quality of life
