【摘要】 目的:探讨下段腰椎小关节突的关节角度及其形态不对称与腰椎间盘突出的相关性。方法:在CT片上观察127例患者的小关节突关节形态、椎间盘是否突出,并测量小关节突关节角度,计算其差值。按年龄分为4组,每个每年龄组中依据两侧小关节突关节角度差值分为<5°、≥5°、≥10°三个组,并将形态不对称纳入关节角度差≥10°组中。在每个年龄组中,对L3~L4、L4~L5及L5~S1节段发生椎间盘突出的病例的不同小关节突角度差值的组间进行组间两两比较;同时,对不同小关节角度差值的各节段椎间盘突出病例的各个年龄组亦进行年龄组间的两两比较;以及不同关节角度差值中,各节段椎间盘突出的总数进行两两比较。结果:在每个年龄组中,各节段椎间盘突出与小关节突角度差值无统计学意义,在不同小关节角度差值的不同年龄组中,仅个别节段椎间盘有统计意义;而在不同小关节角度差值中L3~L4与L4~L5两节段椎间盘突出总数具有统计学意义。结论:下段腰椎椎间盘突出与小关节是否对称无相关性,大多数腰椎间盘突出的病例与年龄亦无明显相关性,而与发生的腰椎节段有相关性。更多还原

【Abstract】 Objective: To study the ralation of lumbar articular facet angle and shape asymmetry to intervertebal disc herniation.Method:The study consisted of four groups in 127 patients,according to the difference of the facet joint shape and angle between rhe right and left sides every group was divided into three of small groups(<5°、≥5°、≥10°).Compared each other of the facet joint asymmetry of the levels of intervertebal disc herniation in the age group and the relationships among the intervertebal herniation of the different age group in the different facet jiont.And compared the sum of intervertebal disc herniation of the levels of lumbar in the different division of facet jiont.Result:There were no statistical significance among the different division of the facet joint shape or angle,and the disc herniation in the age groups.There was significant difference in the sum of disc hernition between the level of L3～L4 and L4～L5 in the different of facet joint shape and angle.Conclusion:There were no correlation between the articular facet angle,shape or age and the intervertebal disc herniation.But the level of intervertebal disc was correlated with herniation.更多还原
