Summary
Bilateral unfused coracoid processes, a rare condition where the coracoid process separates from the scapula, were identified. This finding is crucial for distinguishing it from coracoid fractures in shoulder instability cases.
Area of Science:
- Orthopedic surgery
- Anatomy
- Radiology
Background:
- The coracoid process is integral to shoulder biomechanics.
- Failure of ossification center fusion can lead to anomalies.
Observation:
- A case of bilateral separation of coracoid processes from scapular bodies is presented.
- The condition was incidentally discovered in a patient with recurrent left shoulder dislocation.
- No history of trauma to the coracoid region was reported.
Findings:
- The bilateral unfused coracoid processes are attributed to a failure of fusion between ossification centers.
- This anatomical variation was identified incidentally.
Implications:
- Accurate differentiation from coracoid process fracture or nonunion is clinically significant.
- Understanding this anomaly aids in diagnosing shoulder instability.
- Highlights the importance of recognizing rare anatomical variations in orthopedic assessments.
