Abstract

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.
