Abstrakt		Vertebral stability is defined as the ability of the vertebral column to maintain its normal alignment, to provide support for the head and torso, and to protect neural elements under normal physiologic stress. Stability of the vertebral column depends on the integrity of the major skeletal components, the intervertebral discs, facet joints and the ligaments. Unstable injuries are those that have the potential to cause progressive neurologic deterioration or skeletal deformity under normal physiologic motion or loading. In 1983 Denis developed a new biomechanical theory and classification of vertebral injury. Denis classification was based on the concept of dividing the vertebral column into three distinct anatomic columns.The anterior column extends from the anterior longitudinal ligament to a vertical line drawn trough the junction point of the middle and posterior third of the intervertebral disc. The middle column extends from this line to posterior longitudinal ligament. The posterior column extends from the posterior longitudinal ligament through the supraspinous ligament and thus includes all the posterior skeletal and ligamentous structures. Denis demonstrated that instability would result only when disruption occured in two contiguous zones or when the middle zone was disrupted. This can occur only in conjuction with anterior or posterior disruption, middle zone disruption never occurs alone. Plain radiography, computed tomography (CT) and magnetic resonance imaging (MRI) are imaging tehniques used for the evaluation of spinal trauma. However MRI is not routinely used and its utility as a frontline diagnostic modality in evaluation of spinal trauma is not settled. The purpose of our study was to assess the reliability of each imaging tehnique for evaluation stability of thoracolumbar spinal fractures and compare it with operative findings.
