目的探讨螺旋CT在胸腰段脊椎爆裂性骨折的临床应用价值。方法回顾性分析45例63个脊椎爆裂性骨折的X线及螺旋CT影像资料。结果在63个椎体爆裂骨折中,累及T12～L2 51个椎体,占总数的80.95%,L1受累最高,达25个椎体,占39.68%;椎管狭窄的程度与神经损伤的关系:椎管狭窄程度较轻者,神经损伤较少,椎管狭窄程度较重者,神经损伤较多;单纯依靠CT显示的骨折片向椎管内移位及椎管受压程度判断神经损伤有一定的局限性。结论螺旋CT扫描能很好地显示脊椎爆裂骨折和椎管狭窄的程度,是诊断胸腰椎爆裂骨折的重要方法,并对临床制订治疗方案以起着重要的指导作用。
Objective To investigate the clinical value of spiral CT in the diagnosis of thoracolumbar burst fractures. Methods A retrospective analysis of 45 cases of 63 spondylolisthesis fractures by X-ray and spiral CT image data. Results Of the 63 vertebral burst fractures, 51 of T12 ~ L2 vertebral bodies were involved, accounting for 80.95% of the total. L1 had the highest involvement of 25 vertebral bodies, accounting for 39.68%. The relationship between spinal stenosis and nerve injury: Lesser degree of spinal stenosis, less nerve damage, severe spinal stenosis were more nerve damage; simply rely on CT fracture fragments to spinal canal displacement and spinal nerve compression to determine the extent of a certain Limitations. Conclusion Spiral CT scan can well show the degree of spinal burst fracture and spinal canal stenosis. It is an important method to diagnose thoracolumbar burst fracture. It plays an important guiding role in clinical treatment planning.
