目的：探讨脊柱损伤的ＣＴ 诊断。材料与方法：脊柱损伤８０ 例，其中颈椎６ 例，胸椎１８ 例，腰椎５０ 例，另６ 例为胸１２、腰１ 同时受损。均用ＳＣＴ４５００ ＴＥ ＣＴ 机扫描。结果：（１） 骨折：单纯屈曲压缩型２２ 例，爆裂型３８ 例，安全带型４ 例，骨折脱位型６ 例，其它型１０ 例。（２） 并发症：椎管内血肿４ 例，椎旁血肿２５ 例，椎间盘脱出１０ 例，其它８ 例。结论：ＣＴ 可全面了解骨折程度、范围及细微改变；准确显示椎管变形狭窄程度及范围；准确判断脊柱稳定性；了解是否有并发症。对脊柱序列观察，对脊髓受压、受损的判定有一定局限性。
Objective: To investigate CT diagnosis of spinal injury. MATERIALS AND METHODS: Eighty cases of spinal injuries were obtained, of which 6 were cervical, 18 were thoracic, 50 were lumbar, and 6 were thoracic 12 and 1 were simultaneously impaired. SCT 4500 TE CT scanners were used. Results: (1) Fracture: Simple buckling compression type in 22 cases, burst type in 38 cases, seat belt type in 4 cases, fracture dislocation in 6 cases, the other 10 cases. (2) complications: intraspinal hematoma in 4 cases, 25 cases of paravertebral hematoma, disc herniation in 10 cases, the other 8 cases. Conclusion: CT can fully understand the degree of fracture, range and subtle changes; accurately show the extent and scope of spinal stenosis; accurately determine the stability of the spine; to understand whether there are complications. The observation of the spine sequence, spinal cord compression, impaired judgment has some limitations.
