Effects of Hyperosmolar Dextrose in Rotator Cuff Disorder With Bursitis

Effects of Hyperosmolar Dextrose Injection in Rotator Cuff Disorder With Bursitis : A Randomized Controlled Trial

The main purpose of this study is to compare treatment efficacy of different concentration dextrose injection in chronic subacromial bursitis .

Rotator cuff disorder with bursitis is one of the most frequent pathologies of the shoulder, which may cause serious restriction of daily activities and reduce quality of life. There are many ways in treating rotator cuff disorder with bursitis, including medication, physical therapy, kinesiological taping, acupuncture and local injection. Protholotherapy, which inject hyperosmolar dextrose to soft tissue, is a novel management in musculoskeletal disorders. However, only few trials exist in studying hyperosmolar dextrose injection for rotator cuff disorder with bursitis and most of them have small sample size and not randomized. The aim of this study was to figure out the effects of sonographically guided subacromial bursa injection with hyperosmolar dextrose in rotator cuff disorder with bursitis by a randomized controlled trial.
