Epiphyseal Injuries

What are epiphyseal injuries?

Epiphyseal injuries are injuries that occur at the epiphyseal plate or growth plate of children and adolescents. They commonly occur near the major joints of the limbs, especially the knee, ankle, elbow and wrist.

Doctors Salter and Harris first classified these injuries according to the pattern on X-ray appearance, which also corresponded to their severity. This is the classification that is most commonly used when describing epiphyseal injuries. The Salter and Harris classification of epiphyseal injuries is as follows.

Type 1
Type I injuries occur when the fracture line is along the plane of the epiphyseal plate. If undisplaced, Type I injuries may be missed on X-rays because there is no actual "fracture line" seen.

Type 2
Type II injuries occur when the fracture line is along the plane of the epiphyseal plate, but extends into the metaphysis on one side, giving the "triangle sign" on X-rays.

Type 3
Type III injuries occur when the fracture line is along the plane of the epiphyseal plate, but extends into the epiphysis on one side.

Type 4
Type IV injuries occcur when the fracture line extends from the epiphysis through the epiphyeal plate into the metaphysis.

Type 5
Type V injuries occur when there is a crush injury to the epiphyseal plate. There may be no obvious finding on X-ray, although from the nature of the injury and the clinical signs, a serious injury is to be suspected.

What does your doctor do about it?

X-rays are done to rule out epiphyseal injuries, in children with injuries to their bones near joints. If there is displacement of the fracture, the diagnosis is usually quite obvious. If there is no displacement, especially in the Type I and V injuries, the diagnosis may be made clinically rather than on X-rays.

Type I and II injuries respond well to closed reduction if displaced, and cast immobilization. Type III and IV injuries, if displaced, usually require open reduction and internal fixation to obtain a good result. Type V injuries need to be watched over time. If deformities arise with growth, surgical correction may be needed.
