Between September 2007 and December 2009, stress fractures in adolescent athletes were prospectively submitted to an online database by local high-school athletic trainers. For every radiographically confirmed stress fracture, a standardized online form that detailed each athlete’s demographics, fracture pattern, clinical presentation, sport, level of participation, training intensity and dietary habits was completed. The database created is reported and analyzed within this study. Adolescent stress fractures are an underappreciated entity in the athletic community and sports literature, especially in the adolescent athlete. Significant gender differences highlight the importance of understanding more about this injury. Furthermore, our data suggests that the intensity of training protocols and level of participation may place adolescents at a significantly higher risk of developing a stress injury. Tibia, 48%
