We had a retrospective study for traumatic fracture of spines with simple X-ray and CT. During the period of 2 years from June 1983, the radiological and clinical evaluation had been made on 36 patients suffered from traumatic fracture of spines which were confirmed by the radiological examination. The results were as follows; 1. Among 36 patinets, single spinal injury was 26 cases(72.2%), multiple level injuries was 10 cases(27.7%). 2. Level of spinal injuries were as follows; Most frequent site was thoracolumbar junction(T11-L2) in 19 cases(52.7%), and lower cervical spine(C3-C7) in 9 cases(25%). 3. Simple fracture was in 15 cases(41.6%), burst fractures was in 21 cases(58%). Neurologic symptoms were appeared in 11 cases(52%) in 21 cases of burst fractures. 4. Manifestations of spinal canal narrowing. 2 of 15 cases in simple fracture, all of 21 cases of burst fractures, and we were found exactly posterior element fractures with CT, which were difficult to detect with simple -ray film. 5. Multiplanar reconstruction images were more favorable to detect the distraction of facet joint, fracture through the vertebral endplate, subluxation and kyphosis, which were difficult to detect with axial CT images.
