目的 :通过 CT及 X线影像观察胸腰椎骨折及椎管损伤程度 ,从解剖学角度提出胸腰椎骨折综合分型评分法。方法 :回顾我院 1992— 1998年 12 5例胸腰椎骨折 ,以 Denis三柱理论为基础 ,以 CT及 X线片为依据 ,进行分型评分。结果 :(1)胸腰椎骨折分为六型及相关亚型 ,(2 )骨片突入椎管诊断 ,CT优于普通 X线 ,(3)评分≤ 4分可保守治疗 ,≥ 6分可手术治疗。结论 :CT扫描和 X线片必须相结合才能正确分型评分 ,了解胸腰椎骨折的程度 ,更好指导治疗。 Objective: To observe the degree of thoracolumbar fractures and spinal canal injury by CT and X-ray images, and put forward the comprehensive classification score of thoracolumbar fractures from the perspective of anatomy. Methods: A total of 125 cases of thoracolumbar fractures in our hospital from 1992 to 1998 were retrospectively studied. Based on the Denis three-column theory, CT and X-ray films were used as the basis for classification. Results: (1) The thoracolumbar fractures were divided into six types and related subtypes. (2) The bone chips broke into the spinal canal and CT was superior to the common X-ray. (3) The scores of ≤4 can be conservative treatment, treatment. Conclusion: CT scan and X-ray must be combined to correctly score, to understand the degree of thoracolumbar fracture, better guiding treatment.
