摘要:目的:研究一種能夠顯示頸椎關節突關節及關節間隙的最佳投照攝影位置的方法。方法:觀察50例非脊柱疾病患者,在透視下利用傳統頸椎斜位的基礎上,繼續增大角度20°～25°,使人體冠狀面與床面的夾角逐漸增大至65°～70°角的范圍,此時頸椎(C3～C7)關節突關節在電視上顯示最佳時,然后進行點片獲取C3~C7關節突關節X線照片。結果: 經透視點片獲取422個關節突關節,其中C3顯示48個,C4 為96個,C5 為98個,C6 為98個,C7為82個;經統計學χ2檢驗,頸C3~C7關節突關節在同一椎體的不同側面及性別間顯示率無差異(P gt;0.05)。在攝影時,筆者設計將軀干冠狀面與膠片成65°～70°角的范圍,頸椎略呈屈曲位,頭部略向對側外旋,使頭部冠狀面與膠片成45°角,中心線下移至第五椎體下緣平行射入,經透視確定位置后點片,可得到清晰的關節突關節影像,此攝影位置稱可視頸椎關節突關節投照位。結論:可視的頸椎節突關節投照位置能清晰顯示頸椎關節突關節及關節間隙。
Abstract: 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.
