Summary

This study tested a single injection of 5% dextrose (sugar water) guided by ultrasound to separate the median nerve from surrounding tissues in 37 people with mild-to-moderate carpal tunnel syndrome. Participants were followed for 3 months to see if pain and hand function improved. The goal was to see if this simple procedure could be a safe and effective alternative to surgery.

What this could mean

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

Active substance: 5% dextrose solution
What this could lead to: If it works, this could offer a simple, non-surgical option to reduce pain and improve hand function in people with carpal tunnel syndrome.
What could go wrong: This is a small, single-group study with no comparison group, so results may not be generalizable. The procedure is still experimental and long-term benefits are unknown.
