Q. The marked structure in AP view of spine may be useful to radiologically assess all given entities except?
a. Burst fracture
b. Tumor
c. Fixation of spine
d. Scoliosis
e. Scheurmann disease
Answer -
e
The marked round to oval structure is pedicle.
The burst fracture of vertebrae that results in decrease vertebral height can be seen with increase in distance between two pedicles ( interpedicular distance) in AP view. However the injury is clearer in lateral views.
Tumor of the spine especially at posterior location, are sometimes involve ipsilateral pedicle and the affected side pedicle is not clearly similar to normal opposite one thus displaying radiological sign known as ' winking owl sign'.
Pedicle screw fixation is popular method of fixing spine fractures and screws inside the pedicle can be appreciated in AP view.
In scoliosis like adolescent idiopathic scoliosis, there is asymmetry of size and orientation noted when comparin pedicles of convex and concave side of the scoliotic curve.
Scheurmann disease is osteochondritis or vertebral epiphysitis also known as Scheurmann or juvenile kyphosis.
