Following are radiological features of scurvy except?
Ans. is 'b' i.e., Metaphyseal wideningRadiological features of scurvyo The typical radiological features occur at the ends of long bones, paicularly around knee, i.e. lower end offemur and upper end of tibia. Other common site is proximal end of humerus.o Features are -Ground glass appearace of bone Pencil thin coex White line offraenkel --> represents well calcified cailage in metaphysic. 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 pa 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 -i) Scurvy iii) Plumbism v) Severe protein energy malnutritionii) Healing rickets iv) Acute leukemia vi) Congenital syphilis
