The ligaments and periosteum are stronger than the physis; therefore, they tolerate mechanical forces at the expense of physeal injury. The blood supply to the physis arises from the epiphysis, so separation of the physis from the epiphysis may result in growth arrest. The Salter–Harris classification is used to describe fractures involving the growth plate (Figs. 82-1 and 82-2).
