Transphyseal fracture

Panel A) Group A: Anteroposterior (AP) view of a small infant who had a swollen left elbow after a difficult delivery. The displacement medially of the proximal radius and ulna (arrows) helps to make the diagnosis of a displaced total distal humeral physis. Panel B) Normal elbow for comparison. Panel C) Group B: AP view showing the posteromedial displacement of the distal fragment (arrows). The relationship between the ossification center of the lateral condyle and the proximal radius has been maintained. Panel D) Group C: AP view with marked medial displacement of the distal fragment. Panel E) Group C: lateral view of the same patient showing posterior displacement of the distal fragment. There is also a large metaphyseal fragment associated with the distal fragment (arrow).
