One hundred and twenty-six cases of injuries to the cervical spine seen between 1968 and 1973 were analyzed with regard to the clinical patterns of neurological damage and the roentgenographic patterns of skeletal injury. Those patients with spinal-cord damage could be divided into five groups according to the clinical pattern of neurological damage. Each group had certain characteristic injuries roentgenographically. It is suggested that the proposed classification according to the patterns of neurological damage can be related to the bone injury and that this relationship has a definite place in the initial diagnosis of the mechanism, particularly in difficult cases. The prognosis of the spinal-cord deficit also correlated with the mechanism of injury in the series of cases studied.
