Abstract：Objective:To investigate clinical application value of spiral CT three-dimensional reconstruction in diagnosis of upper cervical spine injury. Method:18 cases of patients with cervical spine injury on X-ray and spiral CT images in our hospital from January 2010 to April 2013 were reviewed.The value of spiral CT three-dimensional reconstruction in diagnosis of upper cervical spine injury were analysed.Result:18 patients,fracture spiral CT findings of 20 parts:2 cases of atlas burst fracture,12 cases of odontoid fractures,2 cases of atlantoaxial vertebral fractures,4 cases of atlantoaxial arch fracture;4 cases of found dislocation:1 case of atlanto-occipital dislocation,3 cases of atlantoaxial dislocation.X-ray examination revealed the fracture site of 12 parts:1 case of fracture of the atlas,7 cases of odontoid fracture,2 cases of atlantoaxial vertebral fractures,2 cases of atlantoaxial arch fracture,misdiagnosis rate of 40%;2 cases of found dislocation:2 cases of atlantoaxial dislocation,misdiagnosis rate of 50%;Including 4 cases of atlantoaxial fractures misdiagnosed as atlantoaxial dislocation. Conclusion:Anatomy of the upper cervical spine because of its complex and subtle,upper cervical spine injury combined with three-dimensional reconstruction of spiral CT scans,can be clearly demonstrated upper cervical spine fracture,dislocation and secondary spinal stenosis,etc.Contribute to the clinical development of treatment programs timely and accurate.
