Comparison of the maximum axial (Z-axis) displacement of the vertebral defect area when the downward inserted angle between the long axis of the screws and superior endplate of the adjacent vertebrae was set to 0° (group A), 5° (group B), 10° (group C), and 15° (group D) during flexion/extension, lateral bending, and rotation. The axial displacement of the injured vertebrae increased with the increase of the angle during flexion/extension, lateral bending, and rotation, but there was no statistical difference among the four groups (P > 0.05)
