目的 探讨脊柱爆裂性骨折 (简称BF)在普通X线与CT扫描中各自的优势、限度及其价值。方法 通过X线正侧位平片和CT轴位扫描对 43例BF的影像学表现进行分析、对比和总结 ,并予以综合分类。结果 43例BF中A型 10例 ,B型 15例 ,C型 2例 ,D型 9例 ,E型 7例 ;三柱损伤 34例 ,二柱损伤 9例 ;椎管狭窄 0度 8例 ,Ⅰ°12例 ,Ⅱ°2 3例 ;脊柱后缘线不连续 35例。结论 X线平片对BF的诊断价值在于反映骨折类型 ,脊柱屈曲、错位和后缘线的改变等骨性改变 ;CT扫描的优势是显示骨折线的走行、范围 ,椎管变形及狭窄程度并推测脊髓神经受压和损伤情况。二者紧密结合 ,相互印证 ,综合分析可提高诊断正确率并协助临床设计正确的治疗方案。
Objective To investigate the advantages, limitations and their respective values of routine spondylectomy (BF) in common X-ray and CT scan. Methods The imaging findings of 43 cases of BF were analyzed, compared and summarized by positive radiographs and CT axial scans and classified. Results Among the 43 BF cases, 10 cases were type A, 15 cases were type B, 2 cases were type C, 9 cases were type D and 7 cases were type E; 34 cases were injured by three columns and 9 cases were injured by two columns; Ⅰ ° 12 cases, Ⅱ ° 2 3 cases; spine posterior margin discontinuous in 35 cases. Conclusion The diagnostic value of X-ray in diagnosis of BF lies in reflecting the changes of bone type such as fracture type, spinal buckling, dislocation and the change of trailing edge. CT scan has the advantage of displaying the fracture line, the extent, the degree of spinal canal deformation and stenosis Speculate spinal nerve compression and injury. The two closely combined, confirming each other, a comprehensive analysis can improve the diagnostic accuracy and help clinical design the correct treatment.
