| 【摘要】 目的：研究胸椎黄韧带骨化（ossification of the ligamentum flavum，OLF）发生年龄、节段分布、形态变化等的流行病学特点。方法：回顾性分析2010年2月以胸部症状来我院就诊的993例患者（男506，女487，年龄5～102岁，平均60岁）的胸部多排探测CT（multidetector computed tomography，MDCT）片、轴位片结合矢状位CT片，分析胸椎黄韧带骨化的患病率及发生的节段、厚度、位置、硬膜囊压迫等情况，观察性别、年龄及发生节段等与ＯＬＦ的关系。患病率采用《北京市2008年人口年龄构成统计》进行人群标化。结果：总体标化患病率为63.9%；男性标化患病率（68.5%）高于女性（59.0%）；50~59岁年龄组的患病率最高（79.2%），但10~19岁人群也有OLF发生，其患病率为50.0%；T10~T11（44.0%）和T11~T12（41.6%）节段ＯＬＦ的患病率亦较高。结论：被调查人群中，胸椎OLF患病率较高，出现年龄较早，发生于下胸段多于中上胸段，患病率与年龄具有一定的相关性。 |

| 【Abstract】 Objective：To evaluate the prevalence，morphology，and distribution of ossification of the ligamentum flavum in thoracic spine.Methods：Retrospective analysis was made on 993 patients（M∶F=506∶487） with chest sympotoms who underwent MDCT since February 2010 in our hospital.The mean age was 60 years(range=5-102).Sagittal and axial images were analysed together.The segment，thickness，location and the condition about the dural sac were recorded.Result：The prevalence in male（68.5%） was higher than that in female（59.0%）.The highest prevalence was in the patients in 50-59 years age group，but OLF also happened early in 10-19 years age group.The highest prevalence was in T10-11（44.0%） and T11-12（41.6%）.Conclusion：The prevalence of ossification of the ligamentum flavum was highest in 50-59 years age group but also happened in early age.OLF occurs more frenquently in the lower than upper and middle thoracic region and its prevalence is getting higher with aging. |
