Summary

This study compares two injection treatments for frozen shoulder (adhesive capsulitis). One group receives a standard steroid injection, while the other gets the same steroid plus extra saline to gently stretch the shoulder capsule. Researchers will measure pain, range of motion, and shoulder function over six months to see if the added fluid helps restore movement better than steroid alone.

What this could mean

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

Active substance
corticosteroid injection with or without saline hydrodilatation
What this could lead to
If hydrodilatation proves superior, it could become a standard, non-surgical treatment for frozen shoulder, offering better mobility without more invasive procedures.
What could go wrong
This is a small, early-stage trial with only 50 participants. The diluted steroid may provide less pain relief, and results may not apply to all frozen shoulder cases.
