Pediatric throwing injuries of the elbow.

Throwing injuries of the elbow in the pediatric population are common. These can occur as lateral compression osteochondral injuries such as osteochondritis dissecans or medial tension overload such as so-called Little League elbow. Extension overload injuries may present in teens as stress injuries of the olecranon process. We review the imaging findings of each of these common injuries, with an emphasis on their magnetic resonance imaging appearance.
