颈椎黄韧带肥厚与性别及年龄的相关研究

Relative study of hypertrophy of ligamentum flavum of cervical vertebra with age and gender

目的:探讨黄韧带的增厚(HLF)与年龄和性别之间的关系。方法:对150例颈椎黄韧带肥厚的患者使用美国GE公司生产的1.5T超导型MRI装置,测量所有的黄韧带厚度。结果:150例患者C3～4、C4～5、C5～6、C6～7水平肥大黄韧带共计562条黄韧带,所统计的黄韧带增厚标准均在横轴位上,黄韧带厚度>3.0mm,黄韧带肥厚多发生于C3～6水平。且随着年龄的增加,黄韧带肥厚的程度也在增加;而男女性别之间黄韧带肥厚发生率无显著性差异。结论:颈椎黄韧带的肥厚与性别无关,与年龄相关,左侧黄韧带增厚几率明显大于右侧。

Objective： To explore the relation between the hypertrophy of ligamentum flavum （HLF） of the cervical vertebra and gender and age. Methods： All 150 patients＇ thickness of the ligamentum flavum in double-side of cervical vertebra were measured by an 1.5 T superconduct MRI system from GE company, USA. Results： Total 562 ligamenta flavum of C3-4、C4-5、C5-6、and C6-7 vertebral level presented hypertrophy, the mean thickness was more than 3 mm on the trans-vers section of the images. HLF was more often occurred in C3-6 level. And it becomes more serious with the age getting older. There was no any difference of the hypertrophy between male and female. Conclusion：The hypertrophy of the ligamentum flavum of cervical vertebra is not related with gender, but there is a significant relation with age. And the incidence of the thickness of left ligamentum avum is much higher than right ligamentum flavum.
