The secret to relief: can radiofrequency really cure shoulder pain?

Shoulder pain is one of the most common complaints among adults, but young athletes also feel it often. When pills and physiotherapy aren't enough, doctors turn to a method called radiofrequency ablation (RFA) of the suprascapular nerve. Basically, a tiny needle sends electromagnetic waves that temporarily "turn off" the pain signal from the nerve. A retrospective study by UW Health examined 31 procedures performed between 2017 and 2024. Before the treatment, patients rated their pain at an average of 6.08 out of 10; after RFA the score dropped to 2.95, a 63 % improvement on average. Benefits lasted about three months, although five procedures showed no change. Researchers concluded that RFA is a solid alternative for those who don't respond to traditional therapies, while noting the limits of a retrospective design. Future larger, controlled studies could confirm whether this technique becomes a long‑term solution for chronic shoulder pain.

Radiofrequency ablation (RFA) works by generating a high‑frequency electromagnetic field (typically 500 kHz‑1 MHz) that heats nerve tissue to 60‑80 °C. This heat causes protein coagulation and membrane denaturation, interrupting nociceptive signal conduction. Two main modes exist: conventional RFA, which creates a continuous thermal lesion, and pulsed radiofrequency (PRF), which delivers brief energy bursts at lower temperatures, reducing collateral damage risk. Targeting the suprascapular nerve is strategic because it innervates about 70 % of the shoulder joint capsule, playing a major role in pain perception. The retrospective study used a paired design, comparing pain scores before and after the procedure with Student's t‑test. While the average pain reduction was statistically significant (p < 0.01), individual variability was high, with five cases showing no improvement. Limitations include the lack of a control group, possible selection of patients more responsive to RFA, and absence of long‑term follow‑up. Future research should employ randomized protocols, incorporate shoulder functional scores (e.g., Constant‑Murley), and assess combined RFA‑physical therapy effects. Moreover, analyzing inflammatory biomarkers pre‑ and post‑procedure could elucidate pain modulation mechanisms beyond simple nerve lesion.
