Abstract
"Reverse cortical sign" is a rare entity described in lumbar burst fracture that corresponds to the fracture fragment of the posterior wall of vertebral body, which has rotated 180 degrees with the cortical surface facing anteriorly and the cancellous surface facing posteriorly in the canal. Identifying this sign is crucial in deciding the line of management as it is a contraindication for ligamentotaxis. The advent of computed tomography scans with axial and sagittal reconstruction has allowed us to better describe these rare entities. We present a lumbar burst fracture with a reverse cortical sign describing its appearance in axial computed tomography scans, sagittal reconstruction, and magnetic resonance imaging.
