三维图像测量青少年颈椎钩突的形态特征

Three-dimensional image for measuring morphological characteristics of cervical uncinate in the adolescent

背景:钩突作为钩椎关节重要组成部分之一,其形态直接影响着颈椎的稳定性和发病率。目的:通过影像学扫描和三维重建分析青少年颈椎钩突的形态特征及发育规律。方法:选择无外伤、无神经症状和体征的6～20岁青少年66名,行多排螺旋CT薄层扫描(0.625～1.25mm),范围C1～T1,将原始数据以DICOM格式导入三维重建软件进行相关指标测量,并按性别、年龄分组进行统计分析。结果与结论:青少年钩突基底长、宽和钩突高、间距从C1～C7均呈递增趋势,且随年龄增长也逐渐递增,但上述所有指标在左右侧别和性别方面差异无显著性意义。钩突倾角在各年龄段中均无明显规律,但变异度较大。表明利用影像资料的三维重建可反映出青少年颈椎钩突随年龄变化的规律及发育特征,为颈椎病的诊断与临床应用提供详实理论依据。

BACKGROUND：Uncinate process is an important part of Luschka joint,and it direct impacts morphological stability and morbidity.OBJECTIVE：To discuss the morphological characteristics and development pattern of cervical uncinate in the youth by scanning and three-dimensional reconstruction imaging measurement.METHODS：Sixty-six young people aged 6 to 20 years were selected with the following standards：no trauma,neurological symptoms and signs.Then,thin line scans of multi-slice spiral CT（0.625-1.25 mm,scope：C1-T1） were carried out.The original data were imported to three-dimensional reconstruction software in DICOM format according to gender,age group for statistical analysis.RESULTS AND CONCLUSION：The basal length,width,height,spacing and angle of uncinate process from C1 to C7 showed an increasing trend,and also showed an increasing trend with age.However,these indicators were not significantly different in gender and side.Uncinate angle in all age groups had no obvious rules,but the variation was larger.Three-dimensional reconstruction of cervical uncinate process by image data reflects the variation of age and developmental characteristics of cervical disease diagnosis and provides detailed theoretical basis for clinical application.
