A shear force of 450\u00a0N was applied to the finite element models at 30\u00b0 flexion to simulate the failure condition. The displacement of the bony fragment and the volume of the bone above 25,000 \u00b5-strain (damaged bone volume) were calculated around the screw path.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>When the screw was implanted through CTP, the displacement of the bony fragment reached the maximum displacement which was 1.10\u00a0mm and the maximum damaged bone volume around the screw path was 148.70 mm<jats:sup>3<\/jats:sup>.
