ABSTRACT
<p><b>OBJECTIVE</b>To investigate the relationship of upper cervical pedicle and vertebral artery (VA) location in order to improve the safety of transpedicular screw insertion.</p><p><b>METHODS</b>The vertebral arteries on 12 sides of 6 adult pate cadaverous specimens were dissected. The distance between VA and VA groove at the atlas needling point of transpedicle screw, and the distance between VA and the inner edge of axis cervical foramen, and the VA external diameter in axis cervical foramen were measured respectively.</p><p><b>RESULTS</b>The distance between VA and VA groove was (1.96 ± 0.72) mm on the left and (1.99 ± 0.61)mm on the right at the atlas needling point of transpedicle screw, the distance between VA and the inner edge of axis cervical foramen was (2.23 ± 0.43) mm on the left and (2.30 ± 0.39) mm on the right, the VA external diameter in axis cervical foramen was (3.03 ± 0.48) mm on the left and (2.98 ± 0.75) mm on the right.</p><p><b>CONCLUSION</b>It is unlikely to injury VA when the transpedicle screws of upper cervical vertebrae were implanted correctly besides high straddled VA, and the individualization must be performed in the process.</p>
