  【摘要】 目的：比较6种颈椎曲度测量方法的可信度及可重复性。方法：随机选取在我科接受颈椎X线检查的80例患者进行标准颈椎侧位拍片，由3名放射科医生采用基于距离[①Borden氏测量法；②颈椎曲度指数（CCI）法；③椎体质心测量法（CCL）测量方法]和基于角度（①C1-C7 Cobb角测量法；②C2-C7 Cobb角测量法；③Harrison氏测量法）共6种测量方法分别测量颈椎曲度。以2周为间隔分别独自测量两次，对测量结果进行统计分析。结果：6种测量方法均具有良好的可信度（r=0.752～0.968）和可重复性（r=0.703～0.915）。基于距离的测量方法中可信度以Borden氏测量法最高（r=0.938～0.968），其次为CCL法（r=0.855～0.908）及CCI法（r=0.775～0.821）；可重复性以Borden氏测量法最好（r=0.888～0.915），其次为CCI法（r=0.819～0.862）及CCL法（r=0.810～0.859）。基于角度的测量方法中可信度以C2-C7 Cobb角测量法最高（r=0.871～0.895），其次为Harrison氏法（r=0.830～0.885）及C1-C7 Cobb角测量法（r=0.752～0.836）；可重复性以Harrison氏法最好(r=0.868～0.880)，其次为C2-C7 Cobb角测量法（r=0.859～0.876）及C1-C7 Cobb角测量法（r=0.703～0.837）。结论：6种不同的颈椎曲度测量方法均具有良好的可信度及可重复性。基于距离的曲度测量方法以Borden氏测量法可信度及可重复性最好，基于角度的曲度测量方法以C2-C7 Cobb角测量法可信度最高，以Harrison氏法可重复性最好。

英文摘要:

  【Abstract】 Objectives: To compare the reliabilities and repetitiveness of six standard methods of assessing cervical sagittal alignment. Methods: Eighty patient′s lateral cervical radiographs were selected. Three radiologic doctors independently evaluated the sagittal alignment by using six standard methods which were divided into distance and angle group. The distance group included cervical curvature index(CCI), cervical vertebra centroid line(CCL) and the Borden methods. The angle group included C1-C7 Cobb, C2-C7 Cobb and the Harrison method. The measurements were performed again two weeks later. Intraobserver and interobserver reliabilities and repetitiveness were measured. Results: The reliabilities and repetitiveness of six standard methods were good. In the distance group, the method with the highest reliability was Borden method(r=0.938-0.968), the next two were CCL(r=0.855-0.908) and CCI method(r=0.775-0.821); the method with the best repetitiveness was Borden method(r=0.888-0.915), the next two were CCI(r=0.819-0.862) and CCL(r=0.810-0.859) method. In the angle group, the method with the highest reliability was C2-C7 Cobb(r=0.871-0.895) method, the next two were Harrison(r=0.830-0.885) and C1-C7 Cobb(r=0.752-0.836) method; the method with the best repetitiveness was Harrison method(r=0.868-0.880), the next two were C2-C7 Cobb(r=0.859-0.876) and C1-C7 Cobb method(r=0.703-0.837). Conclusions: All six methods have good reliabilities and repetitiveness. The Borden method has the highest reliability and repetitiveness in the distance group. The C2-C7 Cobb has the highest reliability and the Harrison method has the highest repetitiveness in the angle group.
