摘　　要：目的：比较Ｘ线摄片和ＣＴ扫描在脊柱骨折中的应用价值。方法：分析了我院１９９３～１９９５年４６例脊柱骨折者的Ｘ线和ＣＴ表现，男３０例，女１６例，年龄２２～８０岁。结果：Ｘ线摄片和ＣＴ扫描发现，Ｘ线片对脊柱单纯屈曲压缩型骨折、椎体脱位、半脱位容易确诊，而对某些类型骨折较易误诊和漏诊，诊断符合率８１．６％。ＣＴ扫描可显示骨折部位、类型、骨折片的移位以及骨折片突入椎管，椎管狭窄，还能显示多节段椎体骨折和附件骨折。椎体骨折均为粉碎性。椎体后缘骨折片不同程度突入椎管，占４８％，与椎体骨折类型有关。ＣＴ扫描诊断符合率达９８．６％。结论：在脊柱损伤的诊断中必须Ｘ线摄片和ＣＴ扫描相结合才能提高脊柱损伤的诊断水平。Objective:In order to compare the value of X—ray film and CT scanning in diagnosis of spinal fracture. Methods: X—ray and CT charecteristic findings of 46 cases with spinal fracture in our hospital from 1993 to 1995.were analysed, There were 30 males and 16 females, age ranging 22～80 years. Results: We found that it is easy to get definite diagnosis with X—ray film in case of simple fiexional compressive, complete and partial dislocation of spine vertebrae, while in distinguishing the type of fracture,X—ray film might mistake or led to misdiagnosis,the total diagnostic corresponding rate was 81.6%. The CT scanning had much advantage in determineing definite location and type of fracture, migration of bone chips in spinal canal,narrowing of spinal canal, and multiple fracture of lumbar body and its appendixes. The rate of the fractre pieces ruptured in varying degrees from the posterior border of vertebral body into the vertebral canal was 48% and it was related to the type of fracture. The diagnostic corresponding rate of CT was 98.6%. Conclusion:the X—ray film combine with CT is very useful in improving the correct diagnostic rate of spinal frature in clinic.
