Trauma of Spine • Motor vehicle accident • Falls • Sport injuries

Trauma of Spine Most common: Upper (C1-C2) cervical spine Lower (C5-C7) cervical spine Thoracolumbar junction (T9-L2)

Imaging studies • X-rays • CT -bones fractures • MRI- soft tissues, spinal cord, CSF, neural roots

Radiology of trauma • Always get two radiographs at 90 degrees to each other! • Look for the second fracture!
