Stability of spinal fractures and fracture dislocations

Posterior longitudinal ligament status in cervical spine bilateral facet dislocations

“…Complete disruption of the posterior column ligament complex, the posterior longitudinal ligament, the intervertebral disc, and the anterior longitudinal ligament have all been described [2,3]. In addition to the previously mentioned injuries, fractures of the articular pillars may be present in bilateral facet dislocation, although these have been thought to be clinically less relevant in comparison to the ligamentous injuries [4]. Bilateral facet fracture-dislocation has traditionally been considered a variation of bilateral facet dislocation, and often has less severe anterolisthsis.…”

Bone Cement Augmentation of Short Segment Fixation for Unstable Burst Fracture in Severe Osteoporosis

“…To overcome these issues, postural reduction using a soft roll can be performed for 2 days when there is not enough space for the transpedicular screw. The usefulness of postural reduction in acute thoracolumbar spinal fracture and conservative treatment of compression fracture with postural reduction have been advocated by many authors 2,15) . Bedbrook noted that 90% of the fractures of the thoracic and lumbar spine could be treated using this closed method.…”

The radiologic assessment of post-traumatic vertebral stability

“…However, he did not take into account impingement of posteriorly extruded bone fragments on the neural elements. Although Holdsworth's work was held in high regard for many years, a number of experimental studies demonstrated that instability could occur only after the additional rupture of the posterior longitudinal ligament and a portion of the annulus fibrosis [1,5,6,13,[15][16][17]. As a result of the work of these investigators Denis, in 1983, developed a new biomechanical theory and classification for vertebral injuries [5,6].…”
