Shin and Kim: Upper Extremity Injuries in Youth Baseball Players

Abstract

The elbow and shoulder in young baseball players are prone to injuries. The internal factors of sports injuries are the fragility of the bones and joints of growing children and adolescents. The main external factors of injuries are the competition and eagerness of adolescent players and the motivation of hard-work. Baseball injuries have many causes, including fast rotation and movement of a load from the trunk to arm, repetitive incorrect placement of the arm in the throwing position, too-many throwing practices, etc. Orthopedic surgeons have generally focused on surgical procedure to cure, but it is time to consider and share the methods of injury prevention.
