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: a line connecting the top of the iliac crests is drawn a second line is drawn perpendicular to the first, which bisects the sacrum. Normal: For coronal balance, a plumb line from the middle of C7 VB should be < 4 cm from [[CSVL]]. Alignment objective: Plumb line from the middleof C7 VB < 4 cm from CSVL. Positive numbers are to the right, negative to left. central_sacral_vertical_line.txt Last modified: 2024/06/07 02:55by 127.0.0.1
