体重指数、关节突关节角度与退变性腰椎滑脱的相关性分析

Correlation Analysis of Body Mass Index,Lumbar Facet Joint Angle and Degenerative Lumbar Spondylolisthesis

目的探讨体重指数、关节突关节角度变化与退变性腰椎滑脱的相关性。方法选取2016年1月至2017年11月在我院诊断为退变性腰椎滑脱的患者共45例,通过收集同期在我院体检患者90例作为正常组,记录患者体重指数,测量L4～5头侧关节突关节角、尾侧关节突关节角、关节突-椎弓根角、左右关节突关节角是否对称,并对这些参数与退变性腰椎滑脱进行相关性分析。结果退变性腰椎滑脱组与正常组相比较,在体重指数、头侧关节突关节角、尾侧关节突关节角、关节突-椎弓根角之间差异有统计学意义(P<0.05);退变性腰椎滑脱组与体重指数、头侧关节突关节角、关节突-椎弓根角可能存在相关性(P<0.05);退变性腰椎滑脱组中左右关节突关节角是否对称与滑脱程度间差异具有统计学意义(P=0.04)。结论退变性腰椎滑脱患者与正常人相比较关节突关节角更加趋于矢状化、关节突-椎弓根角趋于水平化。

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 L 4~5 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.
