Repeated corticosteroid injections into the subacromial space did not increase rotator cuff tear incidence in patients with subacromial impingement. This study suggests corticosteroid use is not a causative factor for rotator cuff tears.
Area of Science:
- Orthopaedic Surgery
- Musculoskeletal Imaging
- Pharmacology
Background:
- Subacromial corticosteroid injections are common for impingement.
- Potential risks include rotator cuff damage.
Purpose of the Study:
- To investigate the association between repeated subacromial corticosteroid injections and rotator cuff tears.
Main Methods:
- Retrospective, case-controlled study.
- 230 patients with subacromial impingement.
- Comparison of rotator cuff tear incidence based on <3 vs. ≥3 corticosteroid injections using MRI.
Main Results:
- No significant difference in age or sex between groups.
- MRI revealed no significant difference in rotator cuff tear incidence between groups (P < 1.0).
Conclusions:
- Subacromial corticosteroid injections do not appear to cause rotator cuff tears in patients with impingement.
- Findings suggest corticosteroid use is not a causative factor for rotator cuff tears in this population.
