Review Question - QID 8247

A 23-year-old man was a restrained backseat passenger in a head-on motor vehicle collision. Examination revealed extensive bruising diagonally across his chest and abdominal areas and extreme pain at the thoracolumbar junction posteriorly. The lateral chest radiograph showed splaying of the spinous processes and increased disk height at the level of the injury, but no fracture of the vertebral bodies. He underwent a posterior spine fusion with instrumentation to stabilize the spine after a full trauma workup revealed the spine to be his only injury. Where is the center of rotation for this injury?
