Features are -

Li Ground glass appearace of bone

Pencil thin cortex


White 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.
