The static plate (ATLANTIS system with fixed-angle screws), the rotationally dynamic plate (ATLANTIS system with variable-angle screws), and the translationally dynamic plate (PREMIER).



The mean percentage (and standard deviation) of load-sharing for the static anterior plate, rotationally dynamic system, and translationally dynamic system with the full-length grafts and

with the grafts that had simulated subsidence of 10%.



The mean range of motion (and standard deviation) after the specimens were loaded in flexion-extension with the static anterior cervical plate, the rotationally dynamic plate, and the

translationally dynamic plate.



The mean range of motion (and standard deviation) after the specimens were loaded in lateral bending with the static anterior cervical plate, the rotationally dynamic plate, and the




The mean range of motion (and standard deviation) after the specimens were loaded in axial rotation with the static anterior cervical plate, the rotationally dynamic plate, and the
