C1-C2 Joint Distraction and Fusion: A Robust Surgical Technique for Atlantoaxial Dislocation with Basilar Invagination

Background: Atlantoaxial dislocation (AAD) and Basilar invagination (BI) are complex craniospinal alignment pathologies with significant clinical morbidity at presentation and a potential for life threatening complications. To realign the craniospinal complex optimally various strategies have been employed over the years ranging from, transoral odontoidectomy to sublaminar wire fixation and in situ screw fixation with significant morbidity and sub-optimal outcomes. This study focuses on our experience with the current treatment strategy of C1-C2 joint distraction and fusion, in managing this complex pathology. Purpose: To study the clinical and
