Frontal

The frontal view shows no apparent bony abnormality, while on the lateral view the dorsal aspect of the physis of the proximal phalanx has opened up, while a subtle cortical buckling can also be discerned on the palmar aspect of its metaphysis.
From the case:
Salter-Harris type II fracture - proximal phalanx

Case Discussion
The fracture of the physis is apparent, while the metaphyseal involvement is more discrete and requires carefuly scrutiny, especially since true Salter-Harris I fractures have a much lower incidence than type II injuries.
