目的比较X线、CT影像学检查在 胸腰椎严重爆裂骨折治疗前、后的应用效 果。方法 选择我院2012年6月-2014年12 月收治的63例胸腰椎严重爆裂骨折患者进 行研究，分别行X线及CT扫描，比较Denis 分型诊断准确性、椎体前缘受压分度诊断 准确性。结果 CT检查的Denis分型与椎体 前缘受压分度确诊准确性分别达95.2%、 92.0%，高于X线84.1%及79.4%，差异有统 计学意义(P＜0.05)。结论 X线可明确损 伤椎体的骨折平面、损伤范围及程度，CT 检查优势更大，可清楚显示骨折细节、脊 柱后柱骨折移位程度、椎管狭窄情况，利 于诊断骨折类型并为手术方案的制定提供 指导，客观条件允许下可联合X线及CT检 查。

Objective To compare the application effect of X-ray and CT examination before and after the treatment of severe burst fractures of thoracolumbar spine. Methods A total of 63 patients with severe burst fractures of thoracolumbar spine admitted into the hospital during June 2012 to December 2014 were studied. X-ray and CT scan were performed, respectively. The accuracy of Denis classificatory diagnosis and diagnosis of vertebral anterior edge compression graduation was compared. Results The diagnostic accuracy of CT in Denis classification and vertebral anterior edge compression graduation were 95.2% and 92.0%, respectively. Compared with 84.1% and 79.4% of X-ray and the difference was statistically significant (P<0.05). Conclusion X-ray can definite the injured vertebral fracture plane, damage extent and degree clear. CT examination is of greater advantage. It can clearly show the fracture details, spinal posterior column displacement fractures and spinal canal stenosis, which is beneficial to define the type of fracture and provide guidance for the formulation of surgical treatment. Objective conditions allowed, X-ray can be combined with CT examination.
