title: Hyperextension spinal fracture.
abstract: Hyperextension thoracolumbar spinal fractures are unusual and occur primarily in patients with ankylosed spines. Early diagnosis to avoid neurologic deterioration requires a high index of suspicion, given the paucity of radiographic findings. The biomechanics of the fracture and its treatment differ from more typical spinal fractures in several important aspects.
