From: MRI-based measurements of spondylolisthesis and kyphosis in degenerative cervical myelopathy
Spondylolisthesis slip (left) measured at the disc level between lines drawn along the posterior surface of the two adjacent vertebral bodies with the largest slip and kyphosis (right) measured using the modified K-line interval: the minimum interval between a line connecting the midpoints of the spinal cord at the level of the inferior endplates of C2 and C7 and the tip of the anterior compression factor
