Abstract
The radiographs and initial clinical findings of 73 patients who had sustained trauma to the cervical spine without bony injury in vehicle collisions were reviewed. The patients were also re-examined clinically two years after the injury. Forty eight (65.8%) had abnormal radiographs at presentation — prevertebral soft tissue swelling in 15 (20.6%), degenerative changes in 15 (20.6%), and an angular deformity between two adjacent vertebral bodies in 27 (37.0%). Prevertebral soft tissue swelling was found to have no significance with respect to clinical outcome and showed no association with the presence of an angular deformity. Degenerative changes are associated with a poor prognosis. The presence of an angular deformity was found to carry a good prognosis in this group of patients. The exact mode of injury is not associated with any specific radiographic appearance except that “roll overs” and side collisions are more likely to cause angulation in the cervical spine.
