This study compared the efficacy and safety of ultrasound-guided versus anatomic landmark-guided corticosteroid injection for the treatment of subacromial impingement syndrome. The results showed that ultrasound-guided injection was more beneficial for pain relief and functional improvement, but had no significant effect on shoulder range of motion.
Objective: The aim of the study was to compare the efficacy and safety of ultrasound-guided versus anatomic landmark-guided corticosteroid injection for the treatment of subacromial impingement syndrome. Design: PubMed, Embase, Web of Science, Cochrane Central Register of Controlled Trials, Scopus, , CBM, CNKI, and Wanfang databases were searched from inception to August 15, 2021, for randomized controlled trials comparing ultrasound-guided versus anatomic landmark-guided injections of corticosteroids for the treatment of subacromial impingement syndrome. Results: Twelve randomized controlled trials with 891 patients were included in this study; 454 patients received ultrasound-guided injections and 437 received anatomic landmark-guided injections. Pooled results showed that ultrasound-guided injection was more beneficial for pain relief (10 trials; mean difference = -0.58; 95% confidence interval = -1.05 to -0.10; P = 0.017) and functional improvement (11 trials; standard mean difference = -0.84; 95% confidence interval = -1.41 to -0.27; P = 0.004). There was no significant difference in shoulder range of motion. In the subgroup analysis, there was a significant difference in pain relief and functional improvement at 6-8 wks and with methylprednisolone. Conclusions: Ultrasound-guided injection of corticosteroids is potentially superior to anatomic landmark-guided injection in improving the clinical symptoms of subacromial impingement syndrome; however, these findings should be interpreted with some caution as the quality of evidence was rated as moderate to very low.
