This systematic review identified 25 studies which assessed the effects of intra-articular corticosteroid injections, as well as the effects of image-guided corticosteroid injections, for the treatment of adhesive capsulitis. A total of 1,429 patients were identified from the 25 studies, and were followed up between 1 to 44 months. Results from the review indicated that corticosteroid injections offer rapid pain relief in the short term, as well as increased range of motion, however long-term effects are similar to other treatments, including placebo. No conclusions could be made regarding the benefits of image-guided corticosteroid injection on shoulder outcomes, as the topic requires further assessment.
