📌Os Acromiale: Hidden Cause of Shoulder Pain and Impingement
1. Importance of Identifying Os Acromiale
- Os acromiale can contribute to shoulder impingement symptoms due to inferior displacement with deltoid contraction.
- It may serve as a contraindication to subacromial decompression surgery in cases of clinical impingement.
- Movement of the os acromiale can lead to osteophyte formation, which impinges on the subacromial space, but symptoms typically arise in middle age.
- Degenerative changes across the synchondrosis or associated acromioclavicular (AC) degeneration may be an isolated source of shoulder pain.
2. Imaging Features
- MRI Characteristics:
- Stress Reaction & Impingement Findings:
3. Surgical Management
- Operative treatment leads to symptom relief and improved clinical outcomes. The surgical approach depends on fragment size and stability:
