We present the case of a competitive swimmer who was 14 years, 9 months old and had a 4-month history of posterior shoulder pain. She was initially evaluated by her school's trainer and completed a 2-week rehabilitation program, but pain returned with return to swimming. After feeling a "pop" while swimming with an increase in associated shoulder pain, the patient presented for medical evaluation. Plain radiographs were read as unremarkable. A formal physical therapy program resulted in increased pain, and the patient returned to clinic within 2 weeks with pain out of proportion to examination. Magnetic resonance imaging at this time identified a stress fracture along the inferior angle of the scapula, prompting a complete shutdown of activity for 4 weeks with vitamin D and calcium supplementation. A physical therapy regimen was restarted at 6 weeks with complete resolution of symptoms and return to swimming at 3 months. This case report is important because it highlights a sports-related stress fracture of the inferior angle of the scapula, a finding not currently present in the literature, in a swimmer, a sport not yet associated with scapular stress fractures.
