Alterations in axial curvature of the cervical spine with a combination of rotation and extension in the conventional anterior cervical approach

摘要

PurposeAlterations of three-dimensional cervical curvature in conventional anterior cervical approach position are not well understood. The purpose of this study was to evaluate alignment changes of the cervical spine in the position. In addition, simulated corpectomy was evaluated with regard to sufficiency of decompression and perforation of the vertebral artery canal.
