Using CT scans of 112 consecutive patients with thoracolumbar burst fractures, we investigated the relationship between traumatic spinal canal stenosis and neurologic deficits. We calculated the stenotic ratios of the area occupied by the retropulsed bony fragments to the estimated area of the original spinal canal. We also examined the shape of the narrowed canal and the disruption of spinal elements. Burst fractures having the following ratios are at significant risk of neurologic involvement: at T11 to T12 with 35% more, at L1 with 45% or more, and at L2 and below with 55% or more.
通过对112例连续的胸腰椎爆裂骨折患者进行CT扫描，我们研究了创伤性椎管狭窄与神经功能缺损之间的关系。我们计算了后凸骨块占据的面积与原始椎管估计面积的狭窄率。我们还检查了狭窄椎管的形状以及脊柱结构的破坏情况。具有以下狭窄率的爆裂骨折有显著的神经受累风险：胸11至胸12节段超过35%，腰1节段45%或更高，腰2及以下节段55%或更高。
