Abstract:Objective To explore the correlation between the body mass index,lumbar facet joint angle and degenerative lumbar spondylolisthesis.Methods A total of 45 cases diagnosed as degenerative lumbar spondylolisthesis in our hospital from January 2016 to November 2017 were enrolled.And 90 cases of healthy controls who had health checkup during the same time were included in normal group.The body mass index was recorded,the lumbar facet joint angle of L4~5 at the cranial side and the caudal side as well as the facet-pedicle angle were measured,and the left and right lumbar facet joint angle were inspected for symmetry. Results Compared with the normal group,the body mass index,the lumbar facet joint angle at the cranial side and the caudal side as well as the facet-pedicle angle were significantly different in the degenerative lumbar spondylolisthesis group (P<0.05).There were possible correlations between the body mass index,the lumbar facet joint angle at the cranial side as,the facet-pedicle angle and degenerative lumbar spondylolisthesis (P<0.05).Also,there was statistical difference between the symmetry of the left and right lumbar facet joint angle and the spondylolisthesis degree in the degenerative lumbar spondylolisthesis group (P=0.04).Conclusion Compared with normal people,the lumbar facet joint angle is more sagittal and the facet-pedicle angle was more horizontal in the patients with degenerative lumbar spondylolisthesis.
