【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. |
