Morphometric evaluation of subaxial cervical spine using multi-detector computerized tomography (MD-CT) scan: The consideration for cervical pedicle screws fixation

Cervical pedicle screw (CPS) insertion is a technically demanding procedure. The quantitative understanding of cervical pedicle morphology, especially the narrowest part of cervical pedicle or isthmus, would minimize the risk of catastrophic damage to surrounding neurovascular structures and improve surgical outcome.
