颈椎损伤的CT诊断

CT Diagnosis of the Injury of Cervical Vertebrae

目的： 分析颈椎损伤的ＣＴ 表现，评价其诊断意义。材料与方法： 回顾分析２６ 例颈椎损伤的ＣＴ 扫描资料。结果： 椎体骨折３４ 节；单椎体骨折７ 例，多椎体骨折６ 例，骨折伴脱位１１ 例，单纯关节脱位２ 例；三柱中以后柱（４７ ％ ） 和前中后柱（２１ ％ ） 骨折多见；椎管和神经孔狭窄率分别为５９ ．１ ％ 、１６ ．２ ％ 。结论： ＣＴ 是颈椎损伤的重要检查手段，是诊断椎管和神经孔狭窄，横突孔破裂、出血，环椎横韧带损伤的有效方法。

Objective: To analyze CT findings of cervical injury and to evaluate them in making diagnosis.Materials and Methods:CT features of cervical injury in 26 cases were retrospectively analyzed.Results:CT findings were as follows: fracture of vertebral body (n=34), single body fracture (n=7), multiple body fracture (n=6), fracture with dislocation (n=11), pure articular dislocation (n=2). Fractures were mostly located in posterior column (47%) and anterior, middle, posterior column (21%). Spinal canal stenosis and neural foramen stenosis were found in 59.1% and 16.2%, respectively.Conclusion: CT is a valuable modality in examining cervical injury and, also, an effective imaging method in demonstrating of spinal or neural foramen stenosis, burst of transverse process foramen, hemorrhage, and the injury of transverse ligament of atlas.
