Acute injuries of the cervical spine are the most common causes of severe disability following trauma, yet the diagnosis of these injuries are often delayed an dthe treatment, inadequate. Traumatic injuries of the cervical spine are diagnosed by radiological examinations And complete evaluations of bony structures and soft tissue changes on conventional radiograms are very important for determining the therapeutic plans and prognoses of the injuried patients. During the period fo 5 years from June 1976 to May 1981, the radiological and clinical evaluation had been made on 38 patients suffered from acute cervical spinal injuries wihich were confirmed by the radiological examinations. The results were as follows : 1. Age distribution of total 38 patients was broad ranging from 19 years to 72 years. 2. The most common cause of injury was traffic accident, next fall down, other accident respectively. 3. Levels of the cervical spinal injuries were as follows ; Upper cervical spine in 15.8%, lower cervical spine in 84.2%, and the most common injuried level was C5. Most of the lower cervical spinal injuries were located in the vertebral body and spinous process. 4. Anatomical sites of the cervical spinal injuries were as follows ; vertebral body in 55.3%, spinous process in 23.7%, neural arch in 15.8%, and locked facet in 18.4%, etc. 5. Most of the patients with severe mental changes were injuried in upper cervical spine rather than lower. And most of the patients with quadriplegia or paraplegia were shown marked disrruption of spinal canal.
