This 1963 instructional course lecture by Salter and Harris introduces the five-type classification of physeal injuries, grounded in experimental animal studies and clinical observation. It asks: can fracture pattern predict risk of growth disturbance, and what treatment principles follow? The classification links fracture line location relative to the growing cells of the physis directly to prognosis and operative decision-making.
Before this paper, physeal injuries had no unified framework linking fracture pattern to expected growth outcome — descriptions varied across institutions with no consistent prognostic or treatment guidance.
This classification gives you a decision rule at the bedside: Types I and II are managed closed; Type III may need open reduction for joint congruity; Type IV always needs open reduction when displaced; Type V warrants protected weight-bearing and honest counseling about near-certain growth disturbance.
When a child presents with ankle or knee pain after a varus/valgus force and the radiograph looks like a sprain, think Type V. The initial film is deceptively normal. The diagnosis is clinical, and the prognosis is poor regardless of how reassuring the X-ray appears.
Follow every physeal injury for at least one year. Growth arrest can be delayed six months or more, and comparative radiographs at six months are the minimum to detect it. The younger the child, the higher the stakes if you miss early closure.
