Little Leaguer’s Elbow is a childhood and adolescent condition in which the growth plate, located at the inner aspect of the end of the humerus next to the elbow, is repeatedly overloaded – usually by excessive throwing in baseball.  

Pain on the pinky side of the elbow is the most common symptom and should be treated with rest and later with reduced pitch count so that the injury does not result in more serious compromise of the growth plate that could lead to permanent bony deformity, pain, and ulnar neuritis.
