中文摘要：

目的：探讨肌骨超声（ musculoskeletal ultrasound， MSUS）评估颈椎钩椎关节有无横向增生的效度。方法23例临床诊断为椎动脉型颈椎病（ cervical spondylosis of vertebral artery type ，CSA）的患者，均行颈部MSUS及CT三维重建与血管成像（3D-CTA）检查，分别评估钩椎关节有无横向增生。以3D-CTA为金标准，对MSUS与3D-CTA的评估结果进行比较和相关性、一致性分析，计算MSUS评估钩椎关节有无横向增生的灵敏度、特异度等指标。结果 MSUS评估钩椎关节有无横向增生的灵敏度、特异度、假阳性率、假阴性率、阳性预测值、阴性预测值、诊断符合率分别为：86.44％、96.80％、3.20％、13.56％、92.73％、93.80％和93.48％。 MSUS和3D-CTA评估结果比较差异无统计学意义（χ2＝0.25，P ＞0.05），两者存在关联性（χ2＝132.52，P＜0.05），相关性较好（ r＝0.65）；并具有极好的一致性（ k＝0.848）。结论 MSUS评估颈椎钩椎关节有无横向增生具有较好的效度。

英文摘要：

Objective To investigate the validity of musculoskeletal ultrasound （ MSUS） for assessing cervical Luschka＆#39;s joint （ UJ） with lateral osteophyte formation .Methods Twenty-three patients clinically diagnosed as arteria vertebral cervical spondylosis （CSA） were examined with both MSUS and 3-dimensional computer tomography angiography （3D-CTA） to assess whether there was a lateral hyperplasia in uncovertebral joint .Use 3D-CTA as the gold standard,the assessment results of MSUS and 3D-CTA were com-pared and the relevance between them were analyzed .The validity of MSUS assessing UJ with lateral osteophyte formation was also cal-culated.Results There was no significant difference between the assessment results of MSUS and 3D-CTA.A good correlation and consistency （Pearson r=0.65,Kappa value=0.848） were found between the two methods .The sensitivity,specificity,positive predic-tive value,negative predictive value and accuracy rate of MSUS were 86.44%,96.80%,3.20%,13.56%,92.73%,93.80% and 93.48%,respectively .Conclusion MSUS has good validity in assessing UJ with lateral osteophyte formation .
