Radiographs show almost all features possible seen in scurvy. The classical ground glass
osteoporosis, cortical thinning, halo ossification center, lateral spurs, and
A deficiency of ascorbic acid causes abnormal function of the osteoblast and defective
osteogenesis resulting in osteoporosis. Clinical symptoms and signs of infantile scurvy,
in order of frequency are irritability, tenderness and weakness of lower extremities, a
scorbutic rosary of the legs, bleeding of the gums (usually where teeth have erupted), and
fever. Normal plasma level of ascorbic acid is 0.6 mg per 100 ml, so a lab value of at
least this level excludes scurvy.
Dense metaphyseal line
This is due to an intensification of the zone of preparatory calcification, resulting from
matrix formation failing, is has been referred to as the white line of Frankel, but is
non-specific, as it is also seen in healing rickets, and lead or phosphorus poisoning.
Ground Glass Osteoporosis
This appears at the end of the shaft with blurring or disappearance of trabecular
Halo Ossification Centre
Also called the Wimberger's ring, it is the same effect that produces the white line of
Frankel, affecting the epiphyseal ossification center.
Seen due to subepiphyseal infraction, or separation of the epiphysis from the metaphysis.
These metaphyseal spurs project at right angles to the axis of the shaft, they may be seen
due to mushrooming of epiphysis on the metaphysis, or may represent earliest calcification
of periosteum elevated by a subperiosteal hemorrhage.
These occur at the end of long bones, seen after about 2 weeks of onset of clinical
symptoms; it is not the periosteal hemorrhage that calcifies, but the elevated periosteum,
secondary to resumption of bone formation.
Subperiosteal comminuted fractures at the end of long bones, extending only partially
through the width of the bone.
Atrophic scurvy line
A radiolucent zone on the shaft side of Frankel's white line, it has been referred to as
the Trummerfeld Zone.
