Summary

This study tests whether wearing a plastic finger splint at night for 6 weeks, right after a cortisone injection, helps trigger finger heal better than the injection alone. Researchers will track pain, finger locking, and daily function in 146 adults over 12 weeks. The goal is to see if this simple, non-surgical approach leads to faster and more complete relief.

What this could mean

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

Active substance
cortisone injection and Oval-8 night splint
What this could lead to
If it works, this could offer a simple, low-cost way to improve trigger finger recovery without surgery.
What could go wrong
This is a small, early-stage study with only 146 participants. The benefit of adding a splint may be small or no better than the injection alone.
