This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This study is testing two different ways to treat chronic low back pain caused by facet joint arthritis (wear and tear in the joints of your spine). One approach uses magnetic resonance-guided focused ultrasound (MRgFUS), which uses sound waves to gently destroy the nerves causing pain. The other uses radiofrequency ablation (RFA), which uses carefully controlled heat to accomplish the same goal. Researchers want to see which treatment works better and is safer for patients.
Chronic low back pain from facet joint arthritis is very common and difficult to treat. While medications and physical therapy help some people, many patients still suffer and need better options. This trial exists to find out if these two newer, less invasive procedures can give patients lasting pain relief without major surgery.

If you join this study, you will receive one of the two treatments—either the ultrasound procedure or the radiofrequency heat treatment—on your facet joints in the lower spine. The procedure takes about 2 hours, and you will need to lie still during it. After treatment, researchers will track your pain levels, how much medication you need, and your ability to do daily activities at regular follow-up visits over 12 months, using questionnaires, physical exams, and imaging studies.
