<prompt> Following are radio-logical features of scurvy exceptBony thickeningMetaphyseal wideningMetaphyseal calcificationEpiphyseal separation  <response>: Radiological feat res of scurvyThe typical radiological features occur at the ends of long bones, particularly around knee, i.e. lower end of femur and upper end of tibia. Other common site is proximal end of humerus.Features are -Li Ground glass appearace of bonePencil thin cortexWhite line offraenkel --- represents well calcified cartilage in metaphysis.Wimburger sign white ring surrounding the epiphyseal centres of ossification.Zone of rarefaction under the white line represents a linear break in the bone, proximal and parallel to white line and epiphyseal separation may occur along this line.Lateral part of this rarefaction is seen as a triangular defect.Palkan spur or lateral spur -- lateral prolongation of white line.During healing phase, subperiosteal hemorrhages becomes calcified and the affected bone assumes a dumbbell or club shape.RememberWhite line of fraenkel is seen in -ScurvyHealing ricketsPlumbism Acute leukemiaSevere protein energy malnutritionCongenital syphilis
