Abstract
BACKGROUND: Nontraumatic spontaneous atlanto-occipital dislocation (AOD) is very rare. In this report, we discuss the technical steps of condylar joint fusion and stabilization (by screws & plates) in nontraumatic AOD. So far our knowledge it is probably the first report of such techniques.
MATERIAL AND METHODS: A young girl and a young man with progressive quadriparesis due to non traumatic 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 joints stabilization and fusion may be a good /or alternative option for AOD.
