What is the imaging modality of choice in younger children, when lateral epicondylar avulsion is suspected?
MRI of the elbow.
How are these injuries treated?
Undisplaced or minimally displaced injuries can be treated conservatively. In significantly displaced fractures, rigid internal fixation allowing early mobilisation or conservative management for these patients also are both options. If the the ossification is displaced into the joint then operative intervention is required.
The lateral epicondyle (L) is the last center of ossification to appear, and as such all the other centers are also visible: capitellum (C), radial head (R), medial epicondyle (M), trochlear (T) and olecranon (O).
