Comparison of ultrasound-guided subacromial corticosteroid and ozone (O₂-O₃) injections in the treatment of chronic rotator cuff tendinopathy: a randomized clinical trial

Abstract

Background: The authors aimed to compare the effects of a one-time ultrasound (US)-guided subacromial corticosteroid injection and three-time ozone (O 2 -O 3 ) injection in patients with chronic supraspinatus tendinopathy. Methods: Participants were randomly assigned to the corticosteroid group (n = 22) or ozone group (n = 22). Injections in both groups were administered into subacromial bursa with an US-guided in-plane posterolateral approach. Primary outcome measure was the change in the Western Ontario Rotator Cuff Index (WORC) score between baseline and 12-weeks post-injection. Secondary outcome measures included visual analog scale and Shoulder Pain and Disability Index scores. Assessments were recorded at baseline, and 4-weeks and 12-weeks post-injection. Results: Forty participants completed this study. Based on repeated measurement analysis of variance, a significant effect of time was found for all outcome measures in both groups. Both the groups showed clinically significant improvements in shoulder pain, quality of life, and function. Baseline, 4-week post-injection, and 12-week post-injection WORC scores (mean ± standard deviation) were 57.

Oxygen-ozone therapy in musculoskeletal disorders: a narrative review

“…Similar results were reported by Atar et al [54] in patients with rotator cuff tendinopathy. In particular, the authors reported lower short-term benefits of O 2 O 3 administration compared with corticosteroid injection, while positive advantages in terms of pain intensity and physical function were shown after 12 weeks [54] .…”

Diagnosis of suprascapular nerve entrapment syndrome based on the infraspinatus muscle cross-sectional area on shoulder MRI

“…First, SNE syndrome has a variety of causes, including trauma, rotator cuff damages, repetitive overhead activities, and the supraspinatus and/or infraspinatus muscles. [20][21][22][23][24][25][26][27][28][29][30] However, we only focused on the infraspinatus muscle. Second, there may be incorrect measurements of IMCSA and SMT in MRS.…”
