ABSTRACT

Cross C2 laminar screwing is a potentially safe and effective technique for both initial and salvage applications of craniocervical and atlantoaxial fixation as well as for incorporation of C2 into sub-axial fixations especially in cases having unsuitable anatomy for pedicle screw fixation. However, a careful preoperative radiologic evaluation is essential to determine the suitability of laminar anatomy for the screw placement on an individual basis. Our purpose of this study is to review previous literature on the anatomical, clinical and radiological basis and to create a useful guidance for C2 translaminar screw fixation.
