脊椎爆裂性骨折合并脊髓损伤的MRI诊断价值

MRI diagnosis of burst fracture of verte-brae merging spinal cord injury

目的探讨脊椎爆裂性骨折合并脊髓损伤的MRI诊断价值。方法对68例脊椎爆裂性骨折合并脊髓损伤的临床及MRI资料进行回顾性分析。结果骨折椎体分布:颈椎6例,胸椎38例,腰椎24例;按神经指标分类:A级16例,B级19例,C级8例,D级12例,E级13例;骨折类型:三柱损伤42例,二柱损伤26例;椎管狭窄程度:0°2例,Ⅰ°20例,Ⅱ°32例,Ⅲ°14例;脊髓损伤程度:脊髓震荡6例,脊髓挫伤45例,脊髓横断17例。结论MRI具有高清晰度、高分辨率并能进行多方位扫描,能够显示骨折程度、骨块移位情况及局部椎管狭窄程度,尤其对脊髓损伤程度能够进行准确评价,能够为临床治疗提供可靠依据。

Objective To evaluate the MRI manifestations and its diagnostic value of burst fracture of vertebrae fracture merging spinal cord injury. Methods The cilinical and MRI data in 68 cases of burst fracture of vertebrae fracture merging spinal cord injury were reviewed. Results Among 68 cases, there were cervical vertebrae burst fractures in 6 cases, thoracic vertebrae in 38 cases, lumbar vertebra in 24 cases; according to the severity of nerve index, type A in 16 cases ,type B in 19 cases ,type C in 8 cases, type D in 12 cases, type E in 13 cases. Fracture type included threecolumn injury in 42 cases ,two-column injury in 26 cases ;the spinal canal narrowing revealed 0° in 2 cases, Ⅰ° in 20 cases, Ⅱ° in 32 cases, Ⅲ° in 14 cases .According to the severity of spinal cord, there were 6 cases with concussion, 45 cases with contusion, 17 cases with transsection. Conclusion With high definition and resolution and the ability of multiaspect scan, MRI can demonstrate the degree and severity of fracture displacements as well as the local spinal stenosis, especially evaluate the severity of spinal cord injury precisely, and provide a reliable basis for clinical treatments.
