摘　　要：目的探讨多层螺旋CT对小儿寰枢椎损伤的诊断价值。方法回顾性分析21例小儿寰枢椎损伤的CT扫描资料。结果齿状突骨折4例,单纯性寰枢关节脱位15例,颈2/3椎体右侧椎小关节半脱位1例,寰枕关节半脱位1例。CT全部诊断正确;X线平片诊断正确13例。结论多层螺旋CT能够清楚地显示小儿寰枢椎骨折和脱位的情况,能准确确定损伤的类型。多层螺旋CT是小儿寰枢椎损伤最好的检查方法,应该常规应用。Objective To evaluate the diagnostic value of multi-slice spiral CT （MSCT） for the atlantoaxial spine injuries in children. Methods The CT findings of 21 cases with the atlantoaxial spine injuries in children were reviewed retrospectively. Results Fractures of dens occurred in 4 cases, isolated atlantoaxial dislocation in 15 cases, sublnxation of the C2/3 right vertebra facet in 1 and atlanto-occipital suhluxation in 1, CT diagnosis was correct in all cases. And plain film diagnosis was correct in 13. Conclusion MSCT could clearly demonstrate the fractures and dislocations of the atlantoaxial spine injuries in children and correctly determine the type of the atlantoaxial spine injuries in children. MSCT is the modality of choice in diagnosis of the atlantoaxial spine injuries in children and should be performed routinely.
