Preschooler with elbow pain after being tackled

Radiograph of ossification centers of the elbow ossifying out of their normal order
AP (left) and lateral (right) radiographs of the elbow show ossification of the capitellum and internal (medial) epicondyle. The radial head is not yet ossified. No fracture or fat pad elevation is seen.

The diagnosis was no fracture of the elbow as the ossification centers of the elbow are ossifying out of their normal order as normally the radial head should ossify before the internal (medial) epicondyle according to the CRITOE mneumonic.
