The Salter Harris  Classification System is used in pediatric epiphyseal fractures.  The higher the type of fracture the poorer the prognosis

Some common exam facts about Salter Harris Fractures are:

1. The type II fracture is the most common.
2. The small metaphyseal fragment in Salter Harris type II and IV fractures is called the Thurston Holland Sign.
3. Type III and IV fractures often require open reduction and internal fracture due to the fracture extending into the joint.
4. Type V fractures may appear normal, but the epiphyseal plate is crushed and the blood supply is interrupted.

The Classification system as listed by Type:

• Type I: A fracture through the physeal growth plate. Typically can not be seen on x-ray unless they growth plate is widened.
• Type II: A fracture through the physeal growth plate and metaphysis.
• Type III: A fracture through the physeal growth plate and epiphysis.
• Type IV: A fracture through the physis, physeal growth plate and metaphysis.
• Type V: A crush injury of the physeal growth plate.
