摘要
目的分析下腰椎关节突关节形态与年龄的相关性。方法选取2018年1月至2020年5月于本院体检中心进行腰椎CT检查的167例体检者为研究对象,将所有研究对象根据年龄划分为青年组(55例)、中年组(56例)和老年组(56例);在CT图像上分别测量各组L4/5关节突关节角和L4/5关节突椎弓根角,比较各组件的差异;在CT横断面图像上评估L4/5关节突关节退变程度并进行比较。结果各组间L4/5关节突关节角和L4/5关节突椎弓根角比较均具有统计学意义(P<0.05);随着年龄的增大,L4/5关节突关节角逐渐缩小,呈负相关关系,L4/5关节突椎弓根角逐渐增大,呈正相关关系;不同年龄组之间L4/5关节突关节退变程度差异具有统计学意义(P<0.05);年龄越大,关节突关节退变程度分级越高。结论年龄越大,腰椎关节发生退行性改变导致腰椎关节突关节结构发生变化的可能性越高,从而引起下腰椎关节发生水平化和矢状化的形态学改变,因而,年龄是导致下腰椎关节突形态发生变化的重要因素。
Objective To analyze the correlation between morphology of lower lumbar facet joint and age.Methods A total of 167 controls who underwent lumbar CT examination in physical examination center of the hospital from January 2018 to May 2020 were enrolled as the research subjects.According to different age,they were divided into adolescent group(55 cases),middle-aged group(56 cases)and elderly group(56 cases).The joint angles and pedicle angles of L4/5 facet joint on CT images in each group were measured.The differences among all groups were compared.The degeneration of L4/5 facet joint on CT cross-sectional images was evaluated and compared among all groups.Results There were significant differences in joint angles and pedicle angles of L4/5 facet joint among all groups(P<0.05).With advancing age,joint angle of L4/5 facet joint was gradually decreased,showing negative correlation,while pedicle angle of L4/5 facet joint was gradually increased,showing positive correlation.There were significant differences in degeneration of L4/5 facet joint among different age groups(P<0.05).The older the age,the higher the degeneration grading of facet joint.Conclusion The older the age,the higher the possibility of structure changes of the lumbar facet joints induced by degenerative changes of lumbar joints,resulting in horizontal and sagittal morphological changes in the lower lumbar joints.Therefore,age is an important factor leading to morphological changes of lower lumbar facet joint.
