Medial Epicondyle Fracture (Humerus)

Return to Main Menu

Resulting from valgus stress, fractures of the medial epicondyle of the humerus (little-leaguer's elbow) are really avulsion injuries. The medial epicondyle (or apophysis) of the humerus is injured by repeated violent contractions of the forearm flexor muscles which arise at this site. This is particularly seen in curveball and slider pitches; these motions result in strong valgus forces being applied at the medial epicondyle.
