Incomplete glenoid ossification: A case report

Abstract

Ossification of the glenoid is a predictable developmental process in adolescents. However, a lack of knowledge of the variability of this process provides a challenge in discerning between normal adolescent development and shoulder pathology. We presented a case of a 15-year-old male with chronic intermittent right shoulder pain who was diagnosed with a labral tear based on presentation, physical exam, and magnetic resonance arthrogram. He subsequently underwent a diagnostic arthroscopy which revealed no evidence of labral or bony pathology and was instead concluded to have an incomplete ossification of the glenoid. His symptoms were assessed to be related to rotator cuff tendinitis, for which he underwent focused physical therapy which resulted in complete resolution of symptoms at his 1-month postoperative follow-up. Understanding the normal ossification process of the glenoid clinically and through imaging can help physicians recognize normal shoulder development and avoid misinterpretation of findings as pathology in adolescent patients.
