Results In 7 cases of odontoid process fracture, X-ray demonstrated 4 cases and CT demonstrated 5 cases, whereas the spiral CT reconstruction diagnosed 7 cases, which could display the displacement of fracture clearly. The X-ray and CT showed asymmetric space between left and right gaps of atlantoaxial joint in 6 cases, while spiral CT reconstruction showed normal and excluded the possibility of atlantoaxial dislocation. There was one case of lateral atlantoaxial joint dislocation, which was demonstrated by the spiral CT reconstruction clearly but not by the X-ray and CT scan. There were 3 cases of atlantoaxial congenital deformity (1 case of absence of both posterior arch of atlas and odontoid process and 2 cases of maldevelopment of the odontoid process), which were displayed clearly by spiral CT reconstruction, but misdiagnosed as odontoid process fracture and atlantoaxial subluxation by X-ray and CT scan.

结果 7例齿状突骨折中，X线显示4例，CT显示5例，CT重建确诊7例，且清楚显示骨折移位情况；6例X线、CT显示寰枢椎左右间隙不对称，通过CT重建排除寰枢关节半脱位；寰枢外侧关节脱位1例，CT重建可清楚显示，而X线片和CT平扫均未能显示；寰枢椎畸形3例，分别为齿状突、后弓缺如1例，齿状突发育不良2例，CT重建均能清楚显示，而X线、CT均误诊为齿状突骨折、寰枢椎半脱位。
