Morphological Features of Spondylolytic Spondylolisthesis

Abstract

The results of radiological measurement of four groups which were consisted of 100 cases of spondylolytic spondylolisthesis, 100 cases of low back pain, 100 cases of spondylolysis and 50 cases of degenerative spondylolisthesis were discussed. In spondylolytic spondylolisthesis, comparing with the other groups, significant decrease of lumbar index and increase of lordosis, laminar angle and lumbosacral angle were observed. These findings suggest that morphological variant is one of the important pathological factors in spondylolytic spondylolisthesis.
