Objective To evaluate clinical and CT features of the 4 th lumbar vertebral spondylolisthesis (L 4DS ) as well as CT value in its diagnosis. Methods CT features of 36 cases of L 4DS were observed and interarticular distance (IAD) and facet joint angle (FJA) were measured and compared with control group.Results Patients with L 4DS mostly were over 40 years old. CT features included degenaration, spondylolisthesis and spinal canal stenosis. IAD and FJA were significantly narrowed.
