What should be done after the dislocation of cervical check?

　　1, X-ray in the cervical violence disappear, because of neck muscle contraction, dislocation of the cervical spine may be ordered back to normal, so ordinary X-ray can show signs of as normal. However, the structure may occur after a small fracture pieces. Thickened prevertebral soft tissue swelling. Intervertebral space in front of the opening increases, the front edge of vertebral body avulsion fracture can occur.
　　In flexion and extension dynamic lateral view, the injured segments showed marked instability, particularly in the extended position, upper body posterior shift, this injury is just the opposite with the buckling, the latter mainly for the upper vertebral body forward flexion shift.
　　2 Magnetic resonance imaging as a high rate of spinal cord injury, magnetic resonance images can show edema in the spinal cord damaged plane, signal enhancement. Cross-section image shows the spinal cord gray and white matter boundaries blurred. In addition, they can still show the rear facet joint capsule impaired.
