摘　　要：目的研究骶骨形态与L5/S1椎间盘突出之间的关系,并探讨其临床意义。方法从南昌大学第一附属医院影像科随机选取行腰骶椎MRI检查者306例,其中L5/S1椎间盘突出组185例,正常对照组121例。在T2WI正中矢状位上测量骶骨基底角与骶骨倾斜角,应用两独立样本t检验比较腰椎间盘突出组与对照组间、男女间骶骨形态的差异性。结果 L5/S1椎间盘突出组与对照组间骶骨基底角、骶骨倾斜角的差异具有统计学意义(P<0.05);L5/S1腰椎间盘突出组内骶骨基底角与骶骨倾斜角男女性别间差异有统计学意义(P<0.05)。结论骶骨的形态与L5/S1椎间盘突出具有相关性;垂直骶骨易导致L5/S1椎间盘突出。Objective To research the relationship between sacral morphology and L5/S1 disc herniation,and to explore its clinical significance.Methods According to lumbosacral spine MRI,306 patients randomly selected from the Department of Radiology of the First Affiliated Hospital of Nanchang University were divided into two groups:L5/S1 disc herniation group(185 patients)and control group(121patients).The sacral base angle and inclination angle were measured on mid-sagittal T2WI.Sacral morphology was compared between the two groups,as well as between men and women using two independent-sample T test.Results There were significant differences in sacral base angle and inclination angle between L5/S1 disc herniation group and control group(P<0.05).Furthermore,the differences were significant between men and women in L5/S1 disc herniation group(P<0.05).Conclusion There is a correlation between sacral morphology and L5/S1 disc herniation.Vertical sacrum may contribute to L5/S1 disc herniation.
