All the following are radiological features of scurvy except (AIIMS May 2009)
|A||White line of Fraenkel|
a. The white line of Fraenkel-a broadened irregular radiopaque line caused by calcified cartilage between the epiphyseal line and the metaphysis.
b. The Pelkan spur-a small bony spur protruding from the lateral and occasionally the medial border of the metaphysis.
c. The scurvy line-the zone of translucency in the metaphysis adjacent to the white line of Fraenkel. The Winberger line-the dense line encircling the epiphysis.
