Figs. 4-A through 4-F This series of radiographs shows a type-6CN curve in a fifteen-year-old girl who had adolescent idiopathic scoliosis.

The sagittal radiograph shows a curve of +17° from the fifth to the twelfth thoracic vertebra, which is equivalent to sagittal thoracic modifier N.

The left side-bending radiograph shows the proximal thoracic curve to be nonstructural, with correction to 18°, and the thoracolumbar/lumbar major curve corrected to 25°.

The right side-bending radiograph shows correction of the main thoracic curve to 32°; thus, it is a structural minor curve.
