Hip dysplasia, subluxation

    Newborn with suspicion of hip dysplasia was addressed to ultrasound.

    At ultrasound left hip angles: alpha = 56 deg, beta = 74 deg(Graf type - II), femoral head is lateralized, coverage 33% (Terjesen type - subluxation).

    At ultrasound: left hip angles: alpha = 45-33 deg, beta = 85 deg: Graf type IIc-IV (physiological delay in ossification - Dislocated), femoral head is lateralized, coverage 32% (Terjesen type - subluxation).

    Another example, a girl 2 months.,

    Graf III-IV(dislocated).

    file 1 - echo

    file 2 - diagram, dotted line shows the normal hip joint(N), regular line - dislocated (D).
