Traditional and cortical trajectory screws of static and dynamic lumbar fixation- a finite element study

BACKGROUND: Two types of screw trajectories are commonly used in lumbar surgery. Both traditional trajectory (TT) and cortical bone trajectory (CBT) were shown to provide equivalent pull-out strengths of a screw. CBT utilizing a laterally-directed trajectory engaging only cortical bone in the pedicl...
