Are Pedicle Screws Dangerous?

World Neurosurgery, 2015
Performing each step is crucial to a high rate of accuracy, and this begins with preoperative assessment of the pedicle anatomy. At a minimum, plain radiographs are reviewed to determine the morphology of the pedicle, and advanced imaging such as computerized tomography (CT) or magnetic resonance imaging can also be of value. Meticulous exposure of the

Lumbar Pedicle Screw Salvage

Journal of Spinal Disorders, 1995
Although research has determined pedicle screw pullout strengths for normal and osteoporotic bone, this study provides the first biomechanical analysis of pedicle screw salvage. Ten fresh frozen human lumbar spines were separated into individual vertebrae; 6.0 x 40 mm pedicle screws were placed in each pedicle; and an axial pullout test was performed ...

Editorial: Pedicle screw navigation

Journal of Neurosurgery: Spine, 2012
In their paper, Mr. Shin and colleagues present a metaanalysis comparing the accuracy of computer-navigated pedicle screw insertions versus nonnavigated techniques.1 The authors only included studies in which both techniques were performed. A total of 18 cohort studies and 2 randomized controlled trials, performed between 2000 and 2011, were evaluated.
