Epiphysiolysis (Salter-Harris I)

Salter-Harris type-I fractures are physeal injuries without epiphyseal or metaphyseal extension. In the proximal tibia, these fractures are classified as 41t-E/1.1.

Displaced Salter-Harris type-I fractures are uncommon.

A small metaphyseal fragment is often present, and the fracture is therefore classified as Salter-Harris II.

An associated fibular fracture may have a different configuration and is classified separately.

Proximal tibial physeal fractures are associated with a high incidence of growth disturbance.

AP and lateral x-rays should be obtained.

Undisplaced Salter-Harris fractures may not be visible on plain x-rays.

These x-rays show a displaced fracture.
