Summary

This study compares two procedures—cryoablation (freezing) and radiofrequency ablation (burning)—to block nerves causing chronic low back pain. 150 adults with long-term back pain will receive one of these treatments or a different endoscopic procedure. The goal is to see which method provides better pain relief and improves daily function over 3 years.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
nerve-blocking procedures (cryoablation or radiofrequency ablation)
What this could lead to
If successful, this could point to a more effective, longer-lasting procedure for chronic low back pain from facet joints.
What could go wrong
This is a single study with 150 participants, and results may not apply to all back pain types. The procedures carry risks like infection or nerve damage.
