The tension of the bone under torsion. On the right: The tension of the nail varying the level of osteotomy. We noted an increase near the osteotomy, which was more pronounced in the 2 cm osteotomy/2 screw configuration. When the tension near the first locking screw is greater (~ 65 Nm), and the stiffness of the bone increases the load forces on the proximal screw
