Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

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.
