The objectives of this study are to compare the clinical outcomes of the three treatment arms: ultrasound guided needle fragmentation with lavage, ultrasound guided needle fragmentation without lavage, and subacromial bursal corticosteroid injection treatment. The study design is a randomized control trial.
The purpose of this study is to determine whether minimally invasive treatments like ultrasound guided needle fragmentation with and without lavage is associated with better clinical outcomes compared to the subacromial bursal corticosteroid injection treatment only.
