  Abstract Study background: Although cervical pedicle screw method is the most stable instrumentation, which is useful for reconstruction of unstable or deformed cervical spine, to insert cervical pedicle screw accurately is sometimes challenging at the risk of the neurovascular injuries due to the anatomical features of cervical pedicles. The purpose of this study is to introduce our Screw Guide Template (SGT) system developed to insert mid-cervical pedicle screws accurately and safely with less risk. Method: Preoperatively, the bone image on CT was analyzed by the multiplanar imaging software and then the trajectory and the depth of the screws were designed three-dimensionally. Three types of transparent templates were created for each lamina: location template, drill guide template and screw guide template. During the operations, after engaging the templates directly with the lamina.. Read More»
