| 摘要: |
| 分析25例脊椎损伤患者的受伤机制与CT表现,认为屈曲性损伤的表现主要是椎体的压缩性骨折;伸展性损伤为脊柱后部结构受损和破裂;纵轴挤压性损伤常伤及脊椎的三柱结构,多为不稳定性骨折;旋转性损伤常造成椎体移位和小关节损害。还对脊柱各段的解剖特点、受伤时生物力学改变进行了讨论。 |

| Abstract: |
| The mechanisms of spinal trauma and their CT images were analysied in the scanning layer of depths 5 to 10 mm for 25 patients with clear cut injury, of which 10 cases are from high falling, 7 from traffic accidents, 5 from slipping and 3 in being blown by a heavy object. The crooked shows the compressive fracture in the front of spine structure and the stretch means the ruptrue in the rear, and the vertical extrusions are mostly unstable fracture, usually touched upon the three column spine structure, and the revolvings often makes spondylolisthesis and harmed the facet joint. The dissect characterristics of parts of spine and the changes of the biomechanics in spinal traumas are also discussed. |
