Which injection works best for carpal tunnel pain? new study to find out
NCT ID NCT07498998
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study will compare three different injections—glucocorticoid, ozone, and 5% dextrose—to see which provides the best pain relief for people with mild to moderate carpal tunnel syndrome. Researchers will enroll 105 adults aged 18 to 65 who have not responded to conservative treatments. The main goal is to measure nerve function and pain levels after treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- glucocorticoid (dexamethasone), ozone, and 5% dextrose
- What this could lead to
- If successful, this could identify a simple, effective injection for easing carpal tunnel pain without surgery.
- What could go wrong
- This is a small, early-stage comparison study with no placebo group, so results may not be definitive. Pain relief may vary and not last long.
