【摘要】：目的:分析正常人群、寰樞關(guān)節(jié)脫位患者的薄層螺旋CT表現(xiàn),篩選出最有效的診斷指標(biāo),制定寰樞關(guān)節(jié)脫位的影像學(xué)診斷標(biāo)準(zhǔn)。方法:收集頸椎正常人群(n=501)、寰樞關(guān)節(jié)脫位患者(n=51)的薄層螺旋CT資料,測量比較2組寰齒前間隙(anterior atlanto-dental interval,AADI)、寰齒后間隙(posterior atlanto-dental interval,PADI)、寰樞椎垂直脫位指數(shù)(vertical atlanto-axial index,VAAI)、寰樞側(cè)方間隙(lateral mass interval,LMI)、寰樞椎相對旋轉(zhuǎn)角度(rotating angle of atlas on dentata,RAAD)、齒突側(cè)方間隙(lateral atlanto-dental interval,LADI)、寰樞椎側(cè)方距離差、寰樞關(guān)節(jié)側(cè)方成角多個參數(shù),統(tǒng)計各型寰樞關(guān)節(jié)脫位例數(shù)并進行統(tǒng)計學(xué)比較。結(jié)果:寰樞關(guān)節(jié)脫位組,AADI、LADI、側(cè)方成角均大于頸椎正常組;PADI、VAAI、LMI均小于頸椎正常組,差異有統(tǒng)計學(xué)意義(均P0.01)。AADI(0.795)、PADI(0.825)、VAAI(0.821)、LADI(0.890)的ROC曲線下面積大,診斷價值高。若滿足下列任意一項,高度提示寰樞關(guān)節(jié)脫位:AADI≥2.2 mm、PADI≤15.4 mm、VAAI≤0.65、LADI≥4.4 mm。寰樞關(guān)節(jié)脫位的類型中,前后脫位7例(13.7%),垂直脫位11例(21.6%),旋轉(zhuǎn)脫位1例(2.0%),側(cè)方橫向平移脫位2例(3.9%),側(cè)方成角脫位1例(2.0%),復(fù)合脫位29例(56.9%)。結(jié)論:AADI、PADI、VAAI、LADI為診斷寰樞關(guān)節(jié)脫位高有效性指標(biāo),根據(jù)測量結(jié)果對寰樞關(guān)節(jié)脫位分型,采取合理的方法進行治療具有重要意義。
[Abstract]:Objective: to analyze the thin slice spiral CT findings of patients with atlantoaxial dislocation and to screen the most effective diagnostic index. Methods: the imaging diagnostic criteria of atlantoaxial dislocation were established. Methods: thin slice spiral CT data were collected from patients with atlantoaxial dislocation of the atlantoaxial joint. The anterior atlanto-dental intervalation, posterior atlanto-dental intervalation, vertical atlanto-axial index and lateral mass intervalation were measured and compared in two groups. The relative rotation angle of atlantoaxial atlanto-axial was rotated angle of atlas on dentate RAADA, the lateral atlanto-dental intervalLADIA of odontoid process, the distance difference of lateral side of axis, and so on were measured and compared between the two groups. The cases of atlantoaxial joint dislocation were counted and compared statistically. Results: the lateral angle of atlantoaxial joint dislocation group was larger than that of normal cervical vertebrae group. The difference was statistically significant (P 0.01. AADI 0.795). The area under the ROC curve was large and the diagnostic value was high. If any of the following items were satisfied, the height indicated that the atlantoaxial dislocation of the atlantoaxial joint was less than 15.4 mm and VAAI 鈮，
