Central sacral vertical line

Last revised by Dr Sachintha Hapugoda on 08 Nov 2018

The central sacral vertical line (CSVL) is used in the assessment of spinal scoliosis

It is a line constructed on frontal films of the spine and pelvis to measure coronal balance, drawn as follows:

  1. a line connecting the top of the iliac crests is drawn
  2. a second line is drawn perpendicular to the first, which bisects the sacrum
