Q

Name the line of mensuration and explain how it is measured:

A

Thoracic kyphosis A line is drawn parallel to and through the superior endplate of the T1 body. A similar line is drawn through the inferior endplate of the T12 body. Perpendicular lines to these endplate lines are then constructed, and the resultant angle is measured at the intersection of the lines.

A

Thoracic kyphosis A line is drawn parallel to and through the superior endplate of the T1 body. A similar line is drawn through the inferior endplate of the T12 body. Perpendicular lines to these endplate lines are then constructed, and the resultant angle is measured at the intersection of the lines.
