The diagnosis of dearticulation of atlantoepistrophic articulation mainly according to measure the ADI. The X-ray pictures and CT were important.

寰枢椎脱位主要通过测量寰枢椎间距离诊断，主要依靠X线平片和CT测量诊断。

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。

Methods A total of 15 cases were fixed and fused with lateral mass screw of atlas and vertebra dentata pedicle screw.

方法采用寰椎侧块螺钉与枢椎椎弓根螺钉技术对15例寰枢椎不稳的患者进行固定。

Objective To summary the results of fixation and fusion with lateral mass screw of atlas combined with vertebra dentata pedicle screw for treatment of atlantoaxial instability and discuss the corresponding therapy methods.

目的总结侧块螺钉与椎弓根螺钉技术治疗寰枢椎不稳的效果，探讨寰枢椎不稳的固定方法。

The huge interarticular contact force of artificial atlanto-odontoid joint at shear and flexion/extension will bring about abrasion, mobilization and destruction of bone or prosthesis. There is potential instability in rotation after replacement operation.

人工寰齿关节置换术后前后向剪切和屈伸运动时人工寰齿关节间的接触应力过大，易造成磨损、引起假体松动和骨或假体的破坏；并且潜在旋转不稳的趋势。

The MPR was used to measure the height and width of posterior arch in the point of vertebra artery overpass, the height of lateral mass benenththe posterior arch and the height and width ofC2 interarticular isthmus.

结果 寰椎椎动脉沟处后弓高度为4.54±1.17mm，椎动脉沟处后弓宽度为8.69±1.12mm，寰椎后弓下侧块高度为4.98±1.07mm，枢椎峡部高度6.95±2.24mm，枢椎峡部宽度6.75±1.39mm，男、女2组之间没有统计学差异。

The new idea, such as the"rotation"of atlas in 3 direction in some of AADs with intact axis, vertebrated odontoid, complete dislocation of AADs with detached odontoid, and differentiation of"dislocation of atlantoaxial joint"and"stenosis of canal"in atlantoaxial subluxation with detached odontoid, are established in this report.

1、本研究提出了一些新的概念，如枢椎完整型AADs时其寰椎在三个方向上的&旋转&脱位、椎体化齿突畸形、齿突不连型AADs的完全脱位、齿突不连的寰枢半脱位时&脱位&和&狭窄&的区分、枕大孔不规则狭窄等为本研究的新的发现或提出的新概念。

Methods the angles from the body surface of yamen (gv 15) to the joint line between the level opposide atlas and axis, and the joint line between body surface of yamen point and posterior margin of the great occipital foramen, upper margin of arcus posterior atlantis were measured respectively in 1120 cases of t1 weighted image of median sigittal position with mri, and the data were processed by computer.

取1120例mri正中矢状位t1加权像，分别测量体表哑门穴至水平相对寰、枢椎椎间的连线与体表哑门穴至枕骨大孔后缘连线、寰椎后弓上缘连线所夹的角度，并由计算机进行数据处理。

It is an effective method to make three-dimensional diagnosis of atlantoaxial subluxation with X-ray photograph and thereafter adopt therapies of acupotomy and spinal manipulation technique.

通过X线片对寰枢椎半脱位作出三维诊断并依此选择针刀和相应的手法整脊治疗，是寰枢椎半脱位诊疗的有效方法。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.
