X-ray study of this region in lateral projection was did, in neutral position and flexion-extension of the neck. The distance between the anterior arch of the atlas and odontoid process as well as the displacement of the basion in relation to the first cervical vertebrae were examined. Twelve patients (17.14 percent) exhibited motion alterations of the region studied: atlanto-axial instability in eight cases (interval bigger than 4.5 mm) and atlanto-occipital instability in four cases.
对70名年龄在5至17岁之间的唐氏综合征患儿（22名男孩和48名女孩）进行了上颈椎不稳的评估。对该区域进行了颈部中立位及屈伸位的X线侧位片检查。测量了寰椎前弓与齿突之间的距离以及颅底相对第一颈椎的移位情况。12例患者（17.14%）表现出所研究区域的运动改变：8例为寰枢椎不稳（间隙大于4.5毫米），4例为寰枕不稳。
