In children, it is vital to assess the physis and look for small changes in its width. When there is angulation of the epiphysis, displacement of the epiphysis on the metaphysis or widening of the physis, think of a Salter-Harris fracture.

Salter-Harris type II injuries are by far the commonest type of physeal injury. When you suspect a type I injury (epiphyseal slip), look carefully for a metaphyseal fragment which makes it a type II injury.
