(B) The disc height (DH) was the average of the disc height(ADH) and posterior disc height(PDH) in the sagittal CT. (C) The foraminal height (FH) was the distance between the inferior edge of the pedicle of the upper vertebral body of CT and the upper edge of the pedicle of the lower vertebral bodyBack to article page
