目的 探析综合治疗胸腰椎爆裂 型骨折效果及CT与MRI应用价值。方法 选择我院2013年1月～2015年5月收治75 例胸腰椎爆裂骨折患者作为研究对象， 分别于术前及术后行CT与MRI检查，比较 手术前后疼痛情况及后凸Cobb角。结果 患者术后，疼痛VAS评分由(6.5±1.6) 分降低至(3.2±0.8)分，凸Cobb角由 (21.8±3.8)°降低至(5.7±1.7)°， 前后差异P＜0.05；并发症总发生率为 21.3%。螺旋CT对患者椎体骨折线、水平 方向的细小骨折、椎管结构、轻微关节 脱位、椎弓骨折、关节内骨折等方面信 息的显示达72.0%，高于MRI的63.2%， MRI对脊髓与损伤及椎体骨髓挫伤的显 示达84.2%，高于螺旋CT的57.3%。结论 综合治疗胸腰椎爆裂型骨折患者疗效满 意，而CT及MRI在患者术前活术后的应 用均具有较大价值，利于诊断及预后评 估。

Objective To ecplore the effects of combined therapy in the treatement of patients with thoracolumbar burst fractures and the imaging application value of CT and MRI. Methods 75 cases of patients with thoracolumbar burst fractures treated in our hospital from January 2013 to May 2015 were taken as the research objects. MRI or CT examination was performed before and after surgery. The pain and kyphose Cobb angle of patients were compared before and after operation. Results After surgical treatment, the pain VAS score (6.5±1.6) was reduced to (3.2±0.8) and convex Cobb angle (21.8±3.8)°decreased to (5.7±1.7)°. The differences were P<0.05. The total incidence rate of complications was 21.3%. The information displayed by spiral CT such as vertebral fracture line, horizontal small fractures, spinal structure, mild joint dislocation, fractures of vertebral arch and intra-articular fracture accounted for 72.0% which was higher than that by MRI 63.2%. The spinal cord injury and vertebral bone marrow contusion showed by MRI accounted for 84.2%which was higher than that by spiral CT 57.3%. Conclusion The curative effect of combined therapy in the treatement of patients with thoracolumbar burst fractures is satisfactory and the application of CT and MRI in patients before and after operation is of great value, which is helpful for the diagnosis and comprehensive evaluation analysis of prognosis.
