Recurrent pain on the inner aspect of the elbow of children and adolescents caused by damage to the sepiphysis (cartilaginous growth plate). The forces produced by repeatedly throwing a baseball can pull off a portion of the cartilage on the humerus (technically called a traumatic avulsion fracture of the medial epicondyle). If treated early, for example, by rest, ice, and immobilization in a splint, the separated growth cartilage can usually reattach. However, if treatment is delayed and the condition deteriorates, surgical fixation may be required. Little Leaguer's elbow is quite common in children in the USA because of the popularity in that country of baseball; the Little League is a junior baseball league. Young baseball players who make more than 350 forceful throws a week are at particular risk of developing Little Leaguer's elbow. Young pitchers are advised to restrict their pitching to less than 250 throws each week. See also epiphysitis.
