Complications Associated with Pedicle Screws*
The Journal of Bone & Joint Surgery, 1999The safety and the effectiveness of pedicle-screw instrumentation in the spine have been questioned despite its use worldwide to enhance stabilization of the spine. This review was performed to answer questions about the technique of insertion and the nature and etiology of complications directly attributable to the screws.We performed a retrospective ...

The Effect of Pedicle Morphometry on Pedicle Screw Loading
Spine, 1997Static nondestructive bending analysis of pedicle screws inserted into vertebral analogues was conducted. Pedicle screw bending load was studied as a function of pedicle morphometry.To determine how sagittal bending moment in pedicle screws is affected by changes in pedicle height, length, and width.An unexpectedly high rate of clinical failure has ...

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, 2012In 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.

Minimally invasive techniques in pedicle screw insertion provide an additional option to a spine surgeon’s armamentarium in dealing with various spine pathologies. It can be applied to practically any surgical setting where conventional open technique is indicated.

During the last two decades transpedicular fixation systems became standard for stabilization in thoracal and lumbar spine surgery [15]. For example, the number of fusions operations, especially for lumbar and lumbosacral degenerative diseases, has increased during that period [36]. In trauma spine surgery it is common to use these implants as well. In
