【摘要】 目的 研究青少年腰骶椎解剖结构发育变异与腰椎间盘突出的关系。方法 通过分析684例15～24岁腰腿痛患者的腰椎CT图像，观察峡部不连、侧弯畸形、移行椎、隐裂、腰骶角、其他(椎旁肌肉、棘突、两侧横突)的解剖发育变异，并分析其与椎间盘突出的相关性。结果 峡部不连、侧弯畸形、移行椎、隐裂、腰骶角、其他(椎旁肌肉、棘突、两侧横突)的解剖发育变异与椎间盘突出的相关性分别为93.6%、92.3%、87.5%、81.3%、72.1%、53.3%;有解剖变异的患者中91.4%出现椎间盘突出，无解剖变异的患者中仅36.2%出现椎间盘突出。结论 腰骶椎解剖结构发育变异是青少年腰椎间盘突出的主要原因，CT检查可以反映两者之间的相关性。更多还原

【Abstract】 Objective To study the correlations among lumbosacral anatomical structure variations and herniation of intervertebral disc.Methods Through analyzing lumbar CT images of 684 patients with lumbocrural pain between 15 to 24 years old,the anatomical variations of spondylolysis,scoliosis deformity,lumbosacral transitional vertebra,subfissure,lumbosacral angle and others(including vertebral muscles beside,spines,transverse process on both sides) were observed,and the correlations among these anatomical variations and herniation of intervertebral disc were analyzed.Results The correlations among these above mentioned anatomical variations and herniation of intervertebral disc were 93.6%,92.3%,87.5%,81.3%,72.1 %,53.3% respectively.In 91.4% of patients,the lumbosacral anatomical structure variations suffered herniation of intervertebral disc at the same time.But only 36.2% of patients suffered herniation of intervertebral disc without lumbosacral anatomical structure variations.Conclusion Lumbosacral anatomical structure variation is the main reason of herniation of intervertebral disc on teenagers.CT examination,which can reflect the correlation between them.更多还原
