The Skeletally Immature and Newly Mature Throwing Athlete

: Injuries to the shoulder and elbow in the pediatric and adolescent throwing athlete are common. Both knowledge of throwing mechanics and understanding of normal bone development in the immature skeleton are key to the diagnosis, treatment, and potential prevention of these common injuries. Pathologic changes from chronic repetitive trauma to the developing shoulder and elbow manifest as distinctly different injuries that can be predicted by the skeletal maturation of the patient. Sites of vulnerability and resulting patterns of injury change as the child evolves from the skeletally immature little league player to the skeletally mature high school/college athlete.
