At the most compressed level, the anteroposterior diameter was defined as the distance between the posterior edge of vertebral body and spinal canal (a, b). The shortest diameter was the distance between the posterior edge of compression and spinal canal (b, c). Spinal canal occupational ratio = (anteroposterior diameter-shortest diameter) / anteroposterior diameter
