目的：探讨压缩性脊椎骨折各节段形态学变化特点。
方法：对412例共448处楔形和爆裂骨折各节段形态学变化进行分析,比较楔形骨折和爆裂骨折各节段的发生概率,计算各节段楔形骨折椎体前缘压缩率、爆裂骨折椎体前后缘压缩比。
结果：中下部胸椎发生楔形骨折概率较高,即使发生爆裂骨折,其椎体前后缘压缩比常较大。腰椎,尤其下腰椎,发生爆裂骨折的概率较高,即使发生楔形骨折,其椎体前缘压缩率相对胸椎而言常较小。
结论：脊椎骨折类型或形态学变化除与暴力、受伤瞬间体位相关外,与骨折发生部位也存在一定关系。 |

Abstract:
Objective:To investigate the morphological charcteristics of compressive fractures in different spinal segments.
Methods:412 cases of patients with 448 wedge and burst thoracic and lumbar fractures were analysed for comparison of the incidence of wedge and burst fractures in different segments,and to calculate compression rate of anterior height of verterbral body to posterior height for burst fracture in every segment.
Results:The incidence of wedge fractures in the middle and lower thoracic spine was comparatively high while during the occurrence of burst fractures in the thoracic segments the ratio between the compression ratio of the anterior and posterior height is comparatively high.In the lumbar spine,especially in the lower lumbar,the incidence of burst fractures was higher than other segments.The compression ratio for burst fracture in the middle and lower thoracic spine was bigger while the compression rate for wedge fracture in the lumbar spine,especially in the lower lumbar in comparison with the thoracic segments,was smaller.
Conclusion:Besides the external violence force and the posture of the patient at the moment of injury,the type or morphologic characteristics of spine fracture is also related to the spinal segments where the fractures take place. |
