Humeral Stress Fracture With Median Nerve Injury in a Baseball Player: A Case Report and Discussion

摘要

There are more than 6 million adolescents participating in baseball in the United States in organized leagues and nearly 13 million more playing in nonorganized leagues according to the Consumer Product Safety Commission (1). Because of the volume of participation in this sport, the number of overuse throwing arm injuries are a significant cause of time loss in adolescent baseball players (2,3). Risk factors for overuse throwing injuries include pitching mechanics, frequency, volume, shoulder rotational range of motion, hip range of motion, decreased posterior shoulder flexibility, rotator cuff weakness and imbalance, and poor neuromuscular control of scapular, core, and lower extremity musculature (4-12). These may result in a variety of upper extremity injuries, such as proximal humeral epiphysiolysis, rotator cuff injury, proximal biceps tendon injury, and ulnar collateral ligament injury (2,13-15).
