An Intraoperative Trajectory‐Determined Strategy of Patient‐Specific Drill Template for C 2 Transoral Pedicle Insertion in Incomplete Reduction of Atlantoaxial Dislocation: An In Vitro Study

Objectives This study aims to explore a novel intraoperative trajectory‐determined strategy of grouped patient‐specific drill templates (PDTs) for transoral C 2 pedicle screw insertion (C 2 TOPI) for atlantoaxial dislocation (AAD) with incomplete reduction and to evaluate its efficiency and accuracy. Methods Ten cadaveric C 2 specimens were scanned by computed tomography (CT) and randomly divided into two groups (the PDT and freehand groups). A...
