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

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

Abstract 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 th...
