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。

Methods: Injured patients of cervical spine was cayyied on X-ray inspection.,then according to the result of ADI and LADS ,next to CT or MRI inspection ,and that was to guide clinical diagonosis and treatment.To observe atlanto-dental interval (anterior arch of atlas posterior border to odontoid process anterior border) and odontoid process caster(included angle between axis of ordinate of odontoid process and axis of ordinate of odontoid vertebra) on the X-ray lateral projection.

对有颈部外伤史的病人常规行X线检查，然后根据寰齿间距和齿突侧块间隙的结果，行下一步CT检查或者MRI检查，指导临床治疗方法的选择。X线侧位片观察寰齿前间隙(为寰椎前弓后缘与齿突前缘距离)，齿状突后倾角(齿突纵轴与枢椎体纵轴的夹角)；开口正位片上测定齿突侧块间隙。

Results: the ratio of cerebellar dentate nucleus volume and the cerebellar volume is 0.6% to 3.9%, the cerebellar dentate nucleus' shape and size is similar;nuclear length(18.12±3.78)mm, height (7.05±3.25)mm, width(7.25±2.20)mm, the nuclear door towards dorsal- medial, 4 tooths account for 55.6%, 5 tooths account for44.4%.

From the simulations, we can see the distributions and transmission of strain and stress in model under different loadings, and the results explained the fractures very well. 4. Similarly, a axis FEM model was constructed to simulate the axis fracture, emphasized on the odontoid process. Three kind of odontoid process fracture were analysed on this model, which occurred respectively on the tip, the middle and the fundus. The results gave the best angle to fracture the odontoid process of the axis.
