OBJECTIVE C2 screw fixation through the pars or pedicle involves a small but finite risk of vertebral artery injury. Recently, C2 crossing laminar screws were described as a method for rigid fixation of the axis. This technique, confined to the dorsal aspect of C2, presents minimal chance of injury to the neighboring neural or vascular structures. METHODS Morphometric analysis was performed on 38 cadaveric spines obtained from the Keck School of Medicine at the University of Southern… CONTINUE READING
