Three injection methods yielded similar clinical improvements for frozen shoulder at 6 months

At 6-month follow-up, intra-articular injection, subacromial injection and hydrodilatation had similar clinical improvements in the treatment of primary frozen shoulder, with hydrodilatation showing more rapid improvement, according to results.

Researchers randomly assigned 86 patients with primary frozen shoulder to undergo either intra-articular injection, subacromial injection or hydrodilatation. Researchers completed evaluations of all patients using the VAS for pain, Simple Shoulder Test, Constant score and passive range of shoulder motion before treatment and at 1 month, 3 months and 6 months after treatment.
