Whiplash causes fracture of odontoid and displaced spinal cord.
Two different types of odon- toid fractures, agenesis and neck. Fracture of odontoid body affects articulation of C1 and C2. Severe neck trauma results in paralysis due to severed cord. Burst fracture of C7 causes contusion of cord with hematoma. Burst fracture at C5 results in typical contused spinal cord.
