BACKGROUND
Nontraumatic spontaneous atlanto-occipital dislocation (AOD) is rare. In this report, we discuss the technical steps of condylar joint fusion and stabilization (by screws and plates) in nontraumatic AOD. To the best of our knowledge, it is the first report of such techniques.
MATERIAL AND METHODS
A young girl and a young man with progressive quadriparesis due to nontraumatic spontaneous atlanto-occipital dislocation were managed by microsurgical reduction, fusion, and stabilization of the joint by occipital condylar and C1 lateral mass screw and plate fixation after mobilization of vertebral artery.
RESULT
In both cases, condylar joints fixation and fusion were done successfully.
CONCLUSION
Condylar joint stabilization and fusion may be a good or alternative option for AOD.
背景
非创伤性自发性寰枕关节脱位（AOD）较为罕见。在本报告中，我们讨论了非创伤性AOD中髁关节融合及稳定术（通过螺钉和钢板）的技术步骤。据我们所知，这是此类技术的首次报告。
材料与方法
一名年轻女孩和一名年轻男性因非创伤性自发性寰枕关节脱位导致进行性四肢瘫，在椎动脉松解后，通过枕髁和C1侧块螺钉及钢板固定进行显微外科复位、关节融合及稳定术。
结果
两例均成功完成髁关节固定及融合。
结论
髁关节稳定及融合术可能是AOD的一种良好或替代选择。
