BACKGROUND There is controversial evidence regarding subacromial injections of nonsteroidal anti-inflammatory drugs and corticosteroid providing pain relief and restoration of function in shoulder impingement syndrome. We wanted to assess and compare the efficacy of subacromial ketorolac and steroids injections in treatment of patients with impingement syndrome. METHODS This study was a double-blind randomized controlled trial. The intervention groups included: A) Ketorolac; B) Triamcinolone;

The patients' pain was recorded based on Visual Analogue Scale system, and performance of patients was recorded based on Oxford Shoulder Score in 0, 2, 4, and 6 weeks. One-way ANOVA, chi-square test and repeated measurement were used to compare and analyse obtained results. RESULTS One hundred five patients were enrolled in the study. Three groups (each one containing 35 patients) were compatible in age and gender. Performance of patients was significantly improved in all three groups over time (p<0.001). The mean pain score of all three groups was significantly decreased over time in the three groups (p<0.001). No significant difference was found for pain scores between the groups at different follow-ups. CONCLUSIONS The results of present study showed that ketorolac, triamcinolone, and betamethasone are equally effective in improving and reducing patients' performance and pain, respectively, in treatment of impingement syndrome. KEY WORDS Shoulder Impingement Syndrome, Ketorolac, Triamcinolone, Betamethasone, Pain HOW TO CITE THIS ARTICLE: Abolhasani H, Falsafi M, Khafri S, et al. Comparison of efficacy of ketorolac, triamcinolone and betamethasone injections in the treatment of shoulder impingement syndrome. BACKGROUND Shoulder pain is the third most common musculoskeletal problem after lumbar and neck pain. (1, 2) In the United States, 3 million visits per year are due to the shoulder pain. (3, 4) A wide range of potential pathoanatomic problems from a simple sprain to a wide rupture of the rotator cuff can cause shoulder pain. (2) The shoulder has the greatest range of motion in the joints of the body. A heterogeneity in size between the smaller cavity of glenoid and the larger head of the humerus can cause shoulder instability. The joint stability is maintained by the two static components of the capsule and the labrum and the dynamic component of the rotator cuff muscles. Inappropriate function in each of these two components can lead to pain, weakness and instability. (5)
