Q. Growth arrest is radiologically seen as
a. Zebra lines
b. Dense metaphyseal band
c. Harris lines
d. Radiolucent lines
Answer -
c
Dense metaphyseal band also called as 'lead line' is seen in lead poisoning.
Zebra lines are seen as alternating pattern of bands of radioopacity seen in metaphyseal area in cases of osteogenesis imperfecta on treatment with bisphosphonates.
Radiolucent lines on the other hand are used for radiological assessment following arthroplasty for loosening of prosthesis.
Harris lines ( after Dr H. Harris) represent growth arrest and are seen as line of increased bone density. These are also called growth resumption lines.
