目的:通过颈椎X线片测量不同年龄人群正常枕颈角度变化。
方法：选取150例不同年龄组健康体检者，男女各75例，年龄20~70（44.83±13.88）岁；共分为5个不同年龄组（20~29岁；30~39岁；40~49岁；50~59岁；60~70岁），每个年龄组30例，每组男女各15例。拍摄150例不同年龄组健康体检者包括头颅在内的颈椎中立位侧位X线片，测量McGregor线（硬腭后上缘与枕骨鳞部外板最低点连线）与C2椎体下缘切线所成的夹角（occipitocervical angle，OCA）及C2椎体后缘连线与硬腭平行线相交所成的角（Takami's occipitocervical angle，TOCA），获得正常人群OCA及TOCA角影像学参数。将所得数据分别按男女组及不同年龄组进行统计学处理，分析OCA及TOCA角之间的相关性。
结果：75例不同年龄人群男性OCA角组平均为（14.71±3.09）°，75例不同年龄人群女性OCA角平均为（14.22±4.27）°；75例不同年龄人群男性TOCA角组平均为（90.50±4.63）°，女性组TOCA角平均为（90.57±6.67）°；不同性别组间OCA及TOCA差异无统计学意义（P>0.05）。将本组150例样本按照5个不同年龄组进行单因素方差分析结果显示各年龄组间OCA及TOCA差异无统计学意义（P>0.05）。相关性研究发现OCA与TOCA角呈正相关（r=0.454，P<0.01）。
结论：该研究提供了西南地区不同年龄组人群的枕颈角度影像学数据，为枕颈融合术确定理想的固定角度提供参考。 |

Abstract:
Objective: To measure imaging data of occipitocervical angle in healthy people at different ages by X-ray.
Methods: One hundred and fifty asymptomatic volunteers(75 males and 75 females) aged from 20 and 70 years old with an average of(44.83±13.88) years old were divided into 5 groups according to different ages(20 to 29 years old,30 to 39 years old,40 to 49 years old,50 to 59 years old and 60 to 70 years old),and 30 people in each group. All people underwent lateral radiography of neck on neutral position. McGregor line (the lowest connection line between upper margin of hard palate and occipital scales of plating),occipitocervical angle(OCA) formed by edge of C2 vertebral body,takami's occipitocervical angle formed between connection line of posterior marginal of C2 vertebral body and parallel lines of hard palate were collected. The data were performed statistical analysis according to gender and different ages,and analyzed correlation between OCA and TOCA.
Results: OCA of 75 males at different ages were (14.71±3.09)° and(14.22±4.27)° in 75 females. TOCA of 75 males at different ages were (90.50±4.63)° and (90.57±6.67) ° in 75 females. There were no statistical difference in OCA and TOCA in people at different ages(P<0.05). There were no significant meaning among 5 groups at different ages in OCA and TOCA(P>0.05). The relation analysis results showed positive correlation between OCA and TOCA(r=0.454,P<0.01).
Conclusion: The paper provided normal values for occipitocervical angle in population of southwestern China between 20 and 70 years old,and results may be useful for posterior occipitocervical fixation and fusion. |
