Then, three cannulated screws (3CS), dynamic hip screws (DHS), dynamic hip screws\n        combined with an anti-rotation screw (DHS + ARS), one-hole femoral neck system (1HFNS), and\n        two-hole femoral neck system (2HFNS) were assembled with the reduction models, respectively,\n        to simulate the internal fixation surgical procedure. All models had a load of 2100\u00a0N in\n        line with the femoral mechanical axis applied. The implant stress, the head and implant\n        displacements, and the rotational angles of all models were recorded and analyzed.<\/jats:p><jats:p>Compared to 3CS and 2HFNS, 1HFNS had higher implant stress (higher than 92.5\u00a0MPa and\n        46.3\u00a0MPa, respectively) and displacement (higher than 0.9\u00a0mm and 0.8\u00a0mm, respectively) in\n        the anatomical reduction. 2HFNS exhibited the highest stress values (225.5\u00a0MPa) in the\n        anatomical reduction but the lowest values (159.8\u00a0MPa) in the positive buttress reduction\n        when compared to the other implants. 2HFNS showed the best rotational stability in the\n        negative and positive buttress reduction (rotational angels of 0.8\u00b0 and 0.6\u00b0,\n        respectively).<\/jats:p><jats:p>Based on the outcome of this computational study, it might be concluded that 2HFNS was\n        an alternative fixation for the treatment of Pauwels type III femoral neck fracture,\n        especially when anatomical reduction cannot be perfectly attained.
