摘要
目的 评价颈前路减压融合术后椎间高度变化的四种测量方法的可靠性。方法 由2名医师分别采用前椎间隙高度直接测量法、椎间隙高度指数法、盘-椎比值法、颈前柱高度测量法,测量68例脊髓型颈椎病手术前后颈椎X线侧位片的椎间高度,计算相应结果,再进行相关性分析。结果 以颈前柱高度测量法的相关系数(0.836)最大,前椎间隙高度直接测量法相关系数(0.639)最小。结论 四种测量方法中,以颈前柱高度测量法最为可靠,测量方法简单实用。
Objective To study the reliability of four methods for the measurement of intervertebral height after anterior cervical decompression and fusion. Methods The intervertebral heights of cervical spine at sixty-eight lateral X-ray films taken preoperatively and postoperatively for the patients with cervical spondylotie myelopathy were measured by two surgeons u-sing four different methods, respectively. The correlation of measurement results was analyzed. Results The method for the measurement of anterior column height had the highest correlation coefficient than other methods, while the method of directly measuring anterior cervical disc space had the lowest correlation coefficient in all the groups. Conclusion This study demonstrated that the method of measuring anterior column height was the most reliable one for the measurement of intervertebral height and it was easy and practical in use.
