Axial translaminar screw placement using three-dimensional fluoroscopy-based navigation.
Journal Title: Singapore Medical Journal - Year 2011, Vol 52, Issue 1
Abstract
To circumvent the risk to the vertebral artery with C2 pars or pedicle screws, C2 laminar screws were considered as a method for rigid fixation of the axis. Although considered to be a relatively safe method, ventral spinal canal violations have been reported. Three-dimensional (3D) fluoroscopy-based image guidance may enhance the accuracy and safety of the technique. There is only one previous report in the literature on its use in the placement of C2 laminar screws. The purpose of this study was to assess the accuracy of C2 translaminar screws inserted using 3D fluoroscopy-based navigation.
