CT of Facet Distraction Flexion Injuries of the Thoracolumbar Spine : The " Naked " Facet 97 . In

چکیده
Vertical distraction of the articular processes is an important sign of ligamentous disruption due to flexion injuries of the thoracolumbar spine. In addition to illustrating this finding in cross section (the "naked" facet), computed tomography in the transaxial plane allows assessment of the presence and position of fracture fragments that may encroach on the spinal canal. Image reconstruction in sagittal and coronal planes provides a clear demonstration of the degree of bony compression, facet distraction, and kyphosis associated with flexion injuries without additional patient manipulation or radiation exposure.

is at the thoracolumbar region, of which more than 50% occur at T11 to L1 levels. More than half of such injuries are sustained in vehicle accidents and 25% are secondary to a fall from a height (usually exceeding 3 meters). Complete neurological deficit has been reported in 25% of such patients and incomplete deficit in about 15%.1 Considerable anatomic differences exist throughout the spinal ...

Background: Thoracolumbar spinal fractures include a range of injuries of various severities from simple apophysealfractures to neurological injury and complex fractures associated with vertebral dislocation. The treatment ofthoracolumbar fractures is challenging, especially due to the difficulty of evaluating the posterior ligamentous complex(PLC). The purpose of this study w...

In thoracolumbar spinal fractures with posterior column injury for applying proper management, it is important to distinguish a flexion-distraction injury (FDI) from a three column burst fracture (BF) as in clinical examination, both may have a similar significant tenderness on direct spinal palpation. Careful attention to the comprehensive clinical examination and detailed imaging features are...

fragments, secure ligaments or tendon to bone, and improve stability in weakened constructs.1–5 The spinous ligaments, ligamentum flavum, facet capsular ligament, and posterior longitudinal ligaments collectively form the natural posterior spinal tension band. The integrity of the posterior spinal ligamentous structures is critical, as they function to limit translation (anterior and posterior)...
