The X-ray films of 40 patients with thoracolumbar fractures were studied in order to classify the fractures, to investigate the causes of neural compression, and to define which fractures were unstable. Each fracture could be classified as a wedge fracture, a burst fracture, or a fracture-dislocation. The fragment of bone that produced neural compression in wedge and burst fractures almost always arose from the upper half of the vertebral body and had a characteristic triangular shape, as viewed on lateral x-ray films of the spine. Based on radiographic evidence, fracture-dislocations, severe burst fractures, and wedge fractures associated with marked subluxation, traumatic spondylolisthesis, or horizontal fractures of a pedicle were considered to be unstable. Mild burst fractures and most wedge fractures were considered to be stable.
对40例胸腰椎骨折患者的X线片进行研究，以对骨折进行分类，调查神经受压的原因，并确定哪些骨折是不稳定的。每一骨折可分为楔形骨折、爆裂骨折或骨折脱位。在楔形和爆裂骨折中产生神经受压的骨碎片几乎总是来自椎体上半部分，从脊柱侧位X线片上看呈特征性的三角形。根据影像学证据，骨折脱位、严重爆裂骨折以及伴有明显半脱位、创伤性椎体滑脱或椎弓根水平骨折的楔形骨折被认为是不稳定的。轻度爆裂骨折和大多数楔形骨折被认为是稳定的。
