    Epiphyseal fractures in children - classification by Salter-Harris and Aitken

    Epiphyseal fractures are fractures that involve the epiphyseal growth plate in children and teenagers. Classificaton by Salter and Harris that was published in 1963 divides them into five types. It is a modification of previous classifications by Poland (1898) and Aitken (1936). Later, several other rare types of epiphyseal fractures were appended by other authors. Epiphyseal fractures may result in growth disturbances. A mnemonic "SALTR" can aid in memorizing the types for the purporses of examination.

    S-H Type Description Mnemonic Aitken
    I transverse fracture through the growth plate S = Slip  
    II fracture through the growth plate and the metaphysis sparing the epiphysis - most common type A = Above the physis I
    III fracture throught the growth plate and epiphysis L = Lower - below the physis II
    IV fracture through the growth plate, metaphysis and epiphysis T = Through III
    V compression fracture of the growth plate with decreased space between the epiphysis and metaphysis on x-ray R = Rammed
