Could a nerve block boost frozen shoulder treatment?

NCT ID NCT07680504

First seen Jul 02, 2026 · Last updated Jul 02, 2026

Summary

This study compares two treatments for frozen shoulder (retractile capsulitis): a standard steroid injection into the shoulder joint versus that same injection plus a nerve block near the shoulder blade. The nerve block uses a numbing medicine and a steroid to calm the nerve that supplies the shoulder. Researchers want to see if the combination improves shoulder function more than the injection alone over three months. About 38 adults with shoulder pain and stiffness lasting 2 to 12 months will take part.

What this could mean

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

Active substance

betamethasone (Diprostene) and lidocaine

What this could lead to

If it works, this combination approach could offer better pain relief and faster recovery for people with frozen shoulder.

What could go wrong

This is a small, early-phase pilot study, so results may not apply to everyone. The nerve block itself carries rare risks like bleeding or nerve damage.
