Abstract
Baseball-related injuries are on the rise due to its increasing popurity as an international sports. Among them, Little League Shoulder is characterized by pain when pitching and is associated with specific roentgenographic changes in adolescent baseball pitchers. Ball thrower's fracture is defined as a fracture of the humeral diaphysis resulting from overhead throwing without any external contact but it is rare in adolescents. We report a case of Little League Shoulder with a contralateral thrower's fracture of the humeral shaft related to baseball pitching in an ambidextrous adolescent baseball pitcher with a review of the relevant literature.
