Ultrasound-guided rotator interval or subacromial corticosteroid injection in primary adhesive capsulitis of the shoulder: Does it make a difference?

Primary adhesive capsulitis occurs spontaneously without any predisposing factors. Diabetes, diseases of thyroid, cerebrovascular accident, coronary artery diseases, autoimmune disease and Dupuytren’s contracture are some of the associated conditions. Various treatment methods for adhesive capsulitis of shoulder including physical therapy, intraarticular corticosteroid injections, manipulation under anaesthesia, and arthroscopic or open capsular release have been described. Intra-articular, subacromial, rotator interval and bicipital grove are the various sites for corticosteroid injection in adhesive capsulitis. Ultrasound has been used widely in shoulder joint injections to improve accuracy. There is limited data comparing these sites for their efficacy in adhesive capsulitis when injected under ultrasound guidance. In this study, we compared ultrasound-guided corticosteroid injection through rotator interval and subacromial route shoulder joint in adhesive capsulitis of shoulder.
