The motion and facet load changes at the adjacent segment after lumbosacral immobilization (with different angles) were quantified in vitro using canine spines. Changes were examined under flexion, extension, and lateral bending. An increase (extension: 62%; flexion: 85%; left bend: 30%; right bend 26%) in motion at the adjacent segment was found for all(More)
BACKGROUND Among all facial fractures, nasal bone fractures are the most common, and they have been reduced by closed reduction (CR) for a long time. But several authors have reported suboptimal results when using CR, and the best method of nasal bone reduction is still being debated.
