Summary

This study looked at 55 adults with severe frozen shoulder (pain and stiffness for at least 3 months) who had not improved with standard treatments. They received one to three injections of steroid and numbing medicine into the shoulder joint, followed by intensive physiotherapy. The goal was to find out which patients respond best, based on MRI and clinical factors, with pain and function measured after one month.

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 (betamethasone or triamcinolone hexacetonide) with lidocaine and saline
What this could lead to
If successful, this could help identify which patients with severe frozen shoulder benefit most from this injection-plus-physiotherapy approach, leading to more personalized treatment.
What could go wrong
This is a small, completed study (55 people) looking for predictive factors, not a large trial testing effectiveness. Results may not apply to all patients, and the procedure carries risks like infection or temporary pain increase.
