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。

Results Seven cases were basilar impression,nine cases were dearticulation of atlantoepistrophic articulation,and five caces were Chiari abnormity.In the X-ray pictures,it showed the abnormal form of the atlas and axis,it also showed the Chamberlain line, according to which we could diagnose the basilar impression.
结果 21例中，颅底凹陷为7例，寰枢椎脱位9例，Chiari畸形5例。X线平片主要表现为寰椎、枢椎形态构异常，并且能显示Chamberlain线，借此可作出颅底凹陷的诊断。

The odontoid vertebra space in the model was divided into lattices and the stress area of the odontoid vertebra was identified by force loading and analyses. It was found that the structure of the stress concentration area was closely related to the development of split sections. Therefore,when the odontoid process is attacked by the external force along its vertical plane,its waist is likely to break and type II fracture occurs. And the break also possibly appears in its base,in this way,type HI fracture occurs.
确定其材料性质、单元类型并控制好网格划分精度后，通过力的加载与分析，找出枢椎的结构应力区，根据结构的应力集中区与其断裂时断裂面走向的密切关系，从而判断出当外部载荷沿齿突中性矢状面不同角度作用，即齿突受到来自其矢状面的外部冲击时，容易在齿突腰部发生断裂，形成枢椎齿突Ⅱ型骨折，也可能在基底部发生断裂，形成枢椎齿突Ⅲ型骨折。

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.
四、建立了枢椎的三维有限元模型，对枢椎齿状突骨折机理进行了理论上的研究，重点针对临床上齿突骨折的三种分类：1、齿突尖骨折；2、齿突腰部骨折；3、齿突基底部骨折，赋予齿状突在矢状面沿各种角度下受力条件，模拟衰椎前弓、襄椎横韧带以及CZ－3棘间韧带对枢椎造成的暴力破坏，确定了最可能引起齿状突暴力骨折的受力角度。
