Boonard M, et al. - Experts undertook a comparative analysis of high volumes (10 cc) of local anesthetic (LA) combined with triamcinolone acetate (TA) with low volumes (4 cc) of LA combined with TA in order to gauge if the latter would provide similar pain, function and complication outcomes for subacromial injections in patients with impingement syndrome. Data illustrated that corticosteroid injections could be used in the treatment of subacromial impingement syndrome. When compared with high-volume (10 cc) corticosteroid injections, non-inferior pain results for VAS score were yielded via low-volume (4 cc) corticosteroid injections.
