胸腰椎爆裂性骨折形态学异常的放射学测量及其与脊髓损伤的关系

目的：探讨胸腰椎爆裂性骨折形态学异常与脊髓损伤的关系。方法：回顾性分析７８例胸腰裂性骨的，根据椎管正中矢状状径计算椎管狭窄率，并按Ｃｏｂｂ法测量后凸畸形角度，同时记录ＡＳＩＡ下肢运动评分结果：无脊髓损伤、不完全脊髓损伤及完全脊髓损伤三组的椎管狭窄率及后凸畸形角度相差无显著统计撑意义（Ｐ〉０．０５），椎管狭窄率及后凸畸形角度与ＡＳＩＡ评分相关笥无显著统计学意义（ＰＭ〉０．０５）。结论：胸腰椎爆裂性骨

Radiographic measurement of morphological abnormalities in thoracolumbar burst fracture: relationship to spinal cord lesion

Objective: To investigate the relationship between morphological abnormalities and spinal cord deficit in thoracolumbar brust fractures. Methods: Seventy eight patients with thorcolumbar burst fractures were retrospectively reviewed to calculate the stenotic ratio of spinal canal based on the midsagittal diameters, and to measure the kyphosis angle according to Cobb, and to record the ASIA scoring of motor function of lower extremities. Results: There was no significant difference ( P >0.05) of the stenotic ratio of spinal canal and the kyphosis angle among the patients without neurological deficit, with incomplete and complete lesions. No significant correlation ( P >0.05) of the stenotic ratio of spinal canal and the kyphosis angle with ASIA scoring was noted. Conclusion: Th severity of spinal cord injuries in thoracolumbar burst fractures in not predicted according to the percentage of spinal canal stenosis or the degree of kyphosis induced by thoracolumbar burst fractures.
