X线片和CT在胸腰椎爆裂性骨折的临床应用效果比较分析

目的比较X线片和CT在爆裂性胸腰椎骨折中的应用效果以及诊断价值。方法通过对2008年1月～2009年9月收治的胸腰椎外伤80例患者中,50例爆裂性胸腰椎骨折患者进行X线片和CT片的特点进行回顾性的分析。其中胸椎15例,腰椎33例,胸腰椎2例,外伤后全部进行正侧位X线片拍摄以及CT扫描,其中5例行冠矢状位重建。结果 50例爆裂性胸腰椎骨折患者中X线片清楚显示33例椎体为爆裂性骨折,CT清楚显示50例爆裂性骨折,与X线片的诊断结果相比差异有统计学意义(P<0.01),椎体内水肿25例,椎板骨折14例,骨折片突入椎管内22例。结论与X线片相比,CT能够更有效地判定爆裂性椎体骨折,并且在显示附件骨折、椎管狭窄、脊神经损伤方面要明显优于X线片。

Objective To investigate the clinical value of X-ray and CT in thoracolumbar bursting fracture. Methods Eighty patients were selected from January 2008 to September 2009,and 50 of them was diagnosed of thoracolumbar bursting fracture,which were 15 cases of ofthoracic vertebra,33 cases of lumbar vertebra, and 2 cases of thoracolumbar vertebra. X-ray and CT scan were performed in all these 80 patients after injury,and the plain film and CT findings were retrospectively analyzed in them. Results In 50 cases,plain film revealed 33 burst facture,and CT findings diagnosed 50 patients,there was statistics significant difference （P0.01）.Fouteen cases of appendix fracture,25 cases of hematoma in vertebral canal and 22 cases if vertebral canal fragment protruded. Conclusion Compared to the plain film,CT is more superior in the diagnosis of thoracolumbar bursting fracture. And CT is more superior in revealing spine three pole structure, and protrusion of interverbral disk and injury of spinal cord and nerve root.It is worthy of clinical application.
