摘要

目的　获取健康人群下颈椎矢状位曲度的相关基础参数，分析其临床意义。方法　选取本院150例健康体检者的站立中立位颈椎侧位片，按照年龄及性别进行分组，测量下颈椎曲度（cervical spinal angle，CSA）、T1倾斜角（T1-slope，TS）、C2~7矢状位轴向距离（C2~7 sagittal vertical axis，C2~7 SVA），并进行统计学分析。结果　健康成人CSA、TS、C2~7 SVA分别为（20.28±6.86）°、（25.81±5.54）°、（15.74±5.96）mm。经独立样本t检验，男女组间CSA、TS有统计学差异（P<0.05），C2~7 SVA无统计学差异（P>0.05）。单因素方差分析显示，CSA、TS、C2~7 SVA随年龄增长逐步增大，TS、C2~7 SVA在不同年龄段差异有统计学意义（P<0.05），女性不同年龄段CSA差异有统计学意义（P<0.05），但男性各年龄段CSA差异无统计学意义（P>0.05）。Person相关分析发现，TS与CSA（r=0.592，P<0.01），TS与C2~7 SVA（r=0.308，P<0.01）呈正相关。结论健康人群CSA，TS存在性别差异，CSA，TS，C2~7 SVA随年龄增长呈现增大趋势；CSA，TS，C2~7 SVA的正常值及TS与CSA和C2~7 SVA正相关性，为颈椎手术中下颈椎矢状位曲度固定提供参考。

Abstract

Objective 　To obtain the basic parameters of sagittal curvature of subaxial cervical spine in normal population and analyze its clinical significance.　Methods　150 healthy volunteers who underwent standing neutral cervical spine lateral X-ray in our hospital were selected and divided into different groups according to age and gender. The data of cervical spinal angle (CSA) ,T1-Slope (TS) and C2~7sagittal Vertical Axis (C2~7 SVA）were measured and recorded.　Results　The CSA, TS and C2~7 SVA values of 150 healthy subjects were (20.28±6.86)°, (25.81±5.54)° , (15.74±5.96) mm, respectively. The independent sample T-test showed that there were significant differences in CSA and TS between male and female groups (P<0.05), and there was no significant difference in C2~7 SVA (P>0.05). One-way ANOVA showed that the values of CSA, TS, C2~7 SVA increased gradually with the increasing of age and the differences of TS, C2~C7 SVA in different age groups were statistically significant (P<0.05). The differences of CSA in different age in female group were statistically significant (P<0.05), but there was no statistical significance in male group (P>0.05). Person correlation analysis showed that TS was positively correlated with CSA and C2~7 SVA (r= 0.592, P<0.01; r= 0.308, P<0.01).　Conclusions　There are differences in CSA and TS between different genders. CSA, TS, C2~7 SVA show an increasing trend with the increasing of age. The values of CSA, TS, C2~7 SVA in normal population and TS are positively correlate with CSA and C2~7 SVA, which can provide reference for the fixation of sagittal curvature of subaxial cervical spine during cervical surgery.
