Abstract

To determine which clinical factors are useful for predicting concomitant injuries of the cervical spine and cervical spinal cord in persons with head injuries, we examined the nature and mechanisms of cervical injuries. For 109 forensic autopsies of persons with head injuries, the cause of injury, mechanism of cervical injury, survival time, and anatomic injury severity (1990 revision of the abbreviated injury scale [AIS] and injury severity score) were determined. Traffic accidents were the most common cause of injuries (41.3%), followed by slips and falls (24.8%), assaults (17.4%), and falls from height (9.2%). The mean maximum AIS scores and the AIS scores of the head or neck were similar in the 4 groups. Cervical spine injuries and epidural or subdural hemorrhages of the cervical spinal cord were more common in persons dying in traffic accidents and falls from height than in persons dying in slips and falls or assaults. Cervical injuries were significantly more common in persons sustaining frontal impacts than lateral or rear impacts. The most common cervical hyperextension injuries were atlanto-occipital and atlantoaxial dislocation and injuries of the 5th intervertebral disc. Our results suggest that persons with injuries of the head due to high-energy frontal impacts should be carefully examined for concomitant cervical injuries. These findings should be helpful for decreasing preventable deaths from undiagnosed cervical injuries in head-injured persons.
