摘　　要：目的:研究一种能够显示颈椎关节突关节及关节间隙的最佳投照摄影位置的疗法。方法:观察50例非脊柱疾病患者,在透视下利用传统颈椎斜位的基础上,继续增大角度20°～25°,使人体冠状面与床面的夹角逐渐增大至65°～70°角的范围,此时颈椎(C_3～C_7)关节突关节在电视上显示最佳时,然后进行点片获取C_3～C_7关节突关节X线照片。结果:经透视点片获取422个关节突关节,其中C_3显示48个,C_4为96个,C_4为98个,C_6为98个,C_7为82个;经统计学x^2检验,颈C_3～C_7关节突关节在同一椎体的不同侧面及性别间显示率无差异(P>0.05)。在摄影时,笔者设计将躯干冠状面与胶片成65°～70°角的范围,颈椎略呈屈曲位,头部略向对侧外旋,使头部冠状面与胶片成45°角,中心线下移至第五椎体下缘平行射入,经透视确定位置后点片,可得到清晰的关节突关节影像,此摄影位置称可视颈椎关节突关节投照位。结论:可视的颈椎节突关节投照位置能清晰显示颈椎关节突关节及关节间隙。Objective：To study the best projection position of cervical articular facet.Methods：The cervical facet angle which was the join angle between sagittal plane of body and the continual line of cervical facet was measured on cervical X-rayed images showed and to the film in 50 healthy people.Results：The facet angle was 65°-70°,during projection, the coronal plane of body in the form of 65°-70°to the film,this projection position was called cervical facet position.Conclusion：seeingredients cervical facet and its interspaces of join can be showed clearly in the cervical facet position of projection.
