This injury may occur with or without retained fracture fragments. Its characteristic appearance resembles that of a plough traversing the earth, and it has historically been termed the plough fracture. Published case reports documenting this specific fracture pattern remain extremely rare in the literature. In our research group\u2032s earlier study on traumatic posterior atlantoaxial dislocation (TPAD), this fracture pattern was categorized as anterior arch fracture type TPAD (TPAD\u2010AOT Type III\n                    <jats:bold>)<\/jats:bold>\n                    . It was further subclassified based on transverse ligament integrity into: (1) Anterior arch fracture type TPAD with intact transverse ligament, and (2) Anterior arch fracture type TPAD with transverse ligament injury, reflecting a progressive increase in instability severity across these subtypes. Hyperflexion and hyperextension injury mechanisms play significant roles in the pathogenesis of this fracture pattern, with definitive diagnosis typically established via CT imaging. The integrity of the transverse ligament is critical for atlantoaxial stability. For patients with an intact transverse ligament, rigid external fixation or internal fixation may be indicated based on fracture displacement and reducibility. However, in cases with transverse ligament injury, posterior C1\u2013C2 fusion typically achieves favourable functional outcomes.\n
