Posterior Facet Distraction and Fusion Technique: Driving a Paradigm Shift in the Surgical Algorithm for Atlantoaxial Dislocation

The PFDF technique provides a safe, effective, and standardized posterior approach for the management of AAD. By achieving reduction through sequential joint release and distraction, PFDF achieves high reduction and fusion rates while minimizing surgical morbidity. This method simplifies the treatment algorithm for AAD, allowing most patients to avoid anterior surgery and its associated complications.
