Plough Fracture (Anterior Arch Fracture Type Traumatic Posterior Atlantoaxial Dislocation, TPAD‐AOT Type III): A Retrospective Study of Nine Clinical Cases With Complete Imaging Data

BioMed Research International, Volume 2026, Issue 1, 2026.
Fracture of the anterior arch of the atlas, accompanied by posterior atlantoaxial dislocation, typically presents on CT imaging as the odontoid process penetrating through and causing a high‐energy shear fracture of the anterior arch. This injury may occur with or without retained fracture fragments.
