摘　　要：目的　研究寰枢关节旋转脱位的CT表现并探索其诊断价值。方法　 3 6例寰枢关节旋转脱位患者行CT扫描 ,9例同时行平片侧位或张口位检查 ;6例正常人行功能性CT扫描。结果　 3 6例寰枢关节旋转脱位CT均可清晰显示寰枢椎间固定角度及寰椎移位、寰枢椎骨折、骨性椎管的形态及周围病变等。平片不能显示寰枢椎之间的旋转情况。正常人寰枢关节可向左右旋转 3 3°～60°。结论　CT可以清晰显示寰枢椎之间旋转情况 。Objective To study the appearance of atlantoaxial rotatory dislocation with CT and to evaluate its value.Methods 36 patients with atlantoaxial rotatory dislocation(AARD) were examined by CT scan.Among them, 9 cases were examined with lateral radiograph and anteroposterior open-mouth radiograph in addition. 6 normal subjects were examined with functional CT scan.Results According to 36 cases with AARD,the fixed angle of atlantoaxial, altas dislocation, fracture, shape of spinal canal and the lesions around could be clearly found on CT image. It was difficult for radiograph to find out atlantoaxial rotatory. The largest atlantoaxial rotatory angle of normal cases was from 33 degree to 60 degree.Conclusion Atlantoaxial rotatory can be properly found with CT scan and atlantoaxial rotatory fixtion is the important foundation for diagnosis of AARD.
