外伤性骨折中以脊柱爆裂性骨折为常见,脊椎受到垂直轴向压力,加上不同程度的屈曲或旋转力作用,髓核向下位椎体内疝入,导致下位椎体内压急剧上升,使椎体由内而外爆裂,常见于高处坠落伤或摔伤,好发于胸腰段[1]。近几年来,螺旋CT后处理软件技术日益成熟,强大而又优越的技术,使用二 In traumatic fractures, spondylolisthesis fractures are common, and vertebrae are subjected to vertical axial compression. Combined with varying degree of flexion or rotation force, the nucleus pulposus is displaced into the lower vertebral body by hernia, resulting in a sharp increase in the pressure of the lower vertebral body. Vertebral body burst from the inside out, common in falling or falling injury, occur in the thoracolumbar [1]. In recent years, spiral CT post-processing software technology is more mature, powerful and superior technology, the use of two
