“Equivalent von Mises stresses” for two different screw configurations. Superior screw 105 mm, inferior screw 105 mm (a). Superior screw 90 mm, inferior screw 90 mm (b). Highest stress levels observed at the superior aspect of the screw (1136 MPa) and at the superior site of the screw hole in the nail (1146 MPa) for both configurations
