$Salter I. Occurs through hypertrophic zone of epiphyseal plate. Only epiphyseal plate is fractured. Rarely produces complications. May be difficult to diagnose unless visible displacement of epiphysis on metaphysis. Slipped capital femoral epiphysis (SCFE) is an example of a Salter-Harris I fracture.$

Salter-Harris II. Most common-85%. Involves both the epiphyseal plate and the metaphysis. Small corner of metaphysis produces the 'corner sign.' Rarely produces complications.

$Salter-Harris III. Involves the epiphyseal plate and the epiphysis itself. Since the epiphysis is involved, damage to the articular cartilage can occur. Growth disturbance is uncommon. Tillaux fracture of the ankle is a Salter-Harris III fracture.$ $Salter-Harris IV. Involves the epiphyseal plate, metaphysis and epiphysis. Since it, too, involves the epiphysis, the articular cartilage can be damaged. These fractures involve the growing layer of cartilage so growth disturbance can result.$

Salter-Harris IV. CT. Involves the epiphyseal plate, metaphysis and epiphysis.

$Salter-Harris V. Rare. Compression injury of epiphyseal plate. Initial diagnosis may be difficult; not made until growth disturbance at epiphyseal plate occurs resulting in angular deformities, such as here. Have the worst prognosis of the Salter-Harris fractures.$

Which type is this? Answer on next slide.

Salter-Harris IV Fracture involving epiphysis, epiphyseal plate and a very small corner of the metaphysis.
