Core Tip	It was difficult to implant traditional trajectory (TT) pedicle screws in the cemented vertebrae. Cortical bone trajectory (CBT) may be a feasible method because of short implantation depth and location at the rear of the vertebrae. We successfully implanted CBT screws in the cemented vertebrae. The application of CBT provides a new method for the fixation of the cemented vertebrae and expands the indication for CBT. Meanwhile, we concluded two tips to decrease the rod curvature and simplify assembly in the hybrid screw technique in which CBT and TT were used in the same set.
