CT三维重建青少年颈椎钩突与椎体各结构的相关性

Correlation of uncinate process and various vertebral body structures in adolescents: three-dimensional reconstruction based on CT images

背景:随着现代生活习惯的改变,使得颈椎病和颈椎相关疾病的发病愈来愈趋于低龄化,基于这一特征,探讨青少年颈椎钩突和椎体间的关系和规律特征,可为颈椎病的早期诊断与预防、治疗提供理论依据。目的:对青少年颈椎钩突与椎体和椎间孔间相关结构进行相关性分析。方法:选取无外伤、无神经症状和体征的6-20岁青少年66例,行多排螺旋CT薄层扫描,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和后期统计分析。结果与结论:(1)除钩突高与椎体中高无显著相关性外,钩突间距与椎体上横径、钩突基底宽与椎体上横径、钩突基底长与椎体上矢径之间均存在正相关性(P<0.05);(2)除椎间孔宽与钩突高以及椎间孔宽与钩突基底宽间无相关性外,钩突高与椎间孔高、钩突基底长与椎间孔高、钩突基底长与椎间孔宽、钩突基底宽与椎间孔高之间均存在正相关性(P<0.05);(3)结果说明,青少年颈椎钩椎关节中钩突与椎体和椎间孔之间存在着一定的相关性,随着年龄的增长、颈椎活动度的增加及脊柱的生长发育,钩突增生、外伤、骨折等因素均可压迫椎间孔内的脊神经从而引起相应的神经根型颈椎病。

BACKGROUND： With the change of modern living habits, the incidence of cervical disease and cervical related diseases is increasingly at younger age. Based on this feature, the discussion of the relationship between the cervical spine and vertebral body as well as regular feature can provide theoretical basis for early diagnosis, prevention and treatment of cervical spondylosis.OBJECTIVE： To analyze the correlation structure of the cervical vertebra uncinate process with the vertebral body and intervertebral foramen among adolescents. METHODS： A total of 66 cases without injuries, neurological symptoms or signs of 6 to 20 years old were scanned with multi-row thin-slice spiral CT from C1-T1. The original data were loaded in DICOM format into three-dimensional reconstruction software for measurement and statistical analysis. RESULTS AND CONCLUSION：（1） In addition to uncinate process height and vertebral body height, the uncinate process spacing, uncinate base width and diameter between the vertebrae and a uncinate process base radius vector length and vertebral bodies were positively correlated（P〈0.05）.（2） Uncinate high uncinate base long uncinate base width and height between the foramen in addition to the uncinate process had a positive correlation with the length of the substrate（P〈0.05）.（3） In conclusion, there is a certain correlation in juvenile cervical uncovertebral joint between the uncinate process and vertebral body and intervertebral foramen. With the growth of age, cervical activity is increased and the uncinate hyperplasia, trauma, and fracture can oppress spinal nerve within the intervertebral foramen to cause corresponding nerve root type of cervical spondylosis.
