Little League Elbow is an overuse injury that occurs on the inside of the elbow at one of the growth plates of the humerus (medial epicondyle). This injury happens after repeated throws and pitches, causing a significant amount of stress to that growth plate.

 

There may be one specific injury or the condition may gradually get worse with repeated throws. There are many risk factors that may influence this injury: years of pitching experience, type of pitches thrown, and strength and flexibility profile of the arm and shoulder.
