The surface rotation of the spine is the value of the horizontal components of the surface normals on the line connecting the spinous processes of the vertebrae A. Lateral deviation of the spinal midline (from spinal process of the 7th cervical vertebra to a midpoint between DL and DR) is measured and calculated as root mean square in the frontal plane B. Kyphotic angle is measured between the surface tangents on points VP (vertebra prominence) and the calculated spinous process of the 12th thoracic vertebrae (T12) C. Lordotic angle is the angle between the surface tangents on points T12 and the midpoint (DM) between DL and DR D. (Images used with kind permission of Diers International GmbH)
