Methods MSCT data of 20 cases of traumatic atlantoaxialjoints were analyzed, the ability of different reconstruction methods in showing the traumatic aspects were evaluated.
方法分析20例环枢关节外伤病例的MSCT资料，观察各种重建方法对病变的显示情况。

The lateral atlantoaxial joint surface is tilted in the sagittal plane or occipito-atlanto-axial joints are asymmetric. Each of the case may result in atlantoaxial dislocation.
寰枢外侧关节面在矢状面上倾斜，枕骨髁、寰椎、枢椎关节发育不对称，可能是导致寰枢椎脱位的另外原因。

The imageology showed that forward atlantoaxial subluxation was verified in 16 cases, which was related with erosive osteoclasia in the atlantoaxial, atlanto-odontoid and atlanto-occipital joints.
