Randomized Controlled Trial
The effect of injection volume on long-term outcomes of US-guided subacromial bursa injections.
Limited data exist on the efficacy of high- compared to low-volume US-guided corticosteroid injections (CI) in the subacromial-subdeltoid (SA-SD) bursa. Our purpose was to compare the short- and long-term efficacy of low- and high-volume injections, by using a capacity reference of SA-SD bursa volume, as assessed on cadaveric specimens. ⋯ High-compared to low-volume US-guided CI are superior for achieving early pain recovery.
