Twenty-one patients with thoracolumbar spinal fractures were studied with computed tomography (CT). A vertebral body was involved in 20; 12 had additional fractures of the posterior elements. Five had multiple level injuries. Neurologic deficits occurred in nine and were more common in combined vertebral body and posterior element injury. Five patients had surgical exploration of the spinal canal. CT provided more information than plain films, which missed a vertebral body fracture in one of 20, spinal canal compromise in four of 17, and posterior element fracture in one of 12. CT showed the posterior element injuries in greater detail. CT with intrathecal contrast material showed dural tear in one case. Dural tears were found at surgery in two additional patients studied without intrathecal contrast. All three had lamina fractures and cauda equina symptoms. Prompt repair of associated nerve root herniation led to rapid recovery in two of these patients.
对21例胸腰椎骨折患者进行了计算机断层扫描（CT）研究。20例累及椎体；12例伴有后部结构骨折。5例为多节段损伤。9例出现神经功能缺损，在椎体和后部结构联合损伤中更为常见。5例患者接受了椎管手术探查。CT提供的信息比平片更多，平片漏诊了20例中的1例椎体骨折、17例中的4例椎管受压以及12例中的1例后部结构骨折。CT更详细地显示了后部结构损伤。鞘内注入造影剂的CT显示1例硬脑膜撕裂。在另外2例未注入鞘内造影剂的研究患者中，手术时发现硬脑膜撕裂。这3例均有椎板骨折和马尾神经症状。及时修复相关神经根疝导致其中2例患者迅速康复。
