Transpedicular screw fixation in the thoracic and lumbar spine with a novel cannulated polyaxial screw system

摘要

Objective:Transpedicular screws are commonly and successfully used for posterior fixation in spinal instability, but their insertion remains challenging. Even using navigation techniques, there is a misplacement rate of up to 11%. The aim of this study was to assess the accuracy of a novel pedicle screw system.
