Objective To study the value of common X-ray and CT scanning in the spinal bursting fracture (abridged English:BF).Methods By the frontal,lateral X-ray film and CT scanning,the imaging manifestations of BF in 43 cases were analysed,contrasted,summarised and classified .Results Among the BF 43 cases,the classifications were type A(10 cases),type B(15 cases),type C(2 cases),type D(9 cases) and type E(7 cases).The three-post injure had 34 cases,the two-post injure had 9 cases,the spinal canal narrowing:0?was 8 cases,1?was 12 cases,2? was 23 cases;the rear spinal edges discontinuation was 35 cases.Conclusion The diagnostic value of X-ray film to BF is reflecting the bones injured change of spinal fracture type,flexion and damaged rear edge.The CT scanning advantage is showing the fracture lines trend,relative scope,degree of spinal canal deformation and narrow,infering the pressed situation and injured spinal cord.The two methods combine and confirm each other in order to help clinical diagnosis the right treating.
