A Biomechanical Comparison of Trochanteric Nail Proximal Screw Configurations in a Subtrochanteric Fracture Model

Abstract

This study shows that axial failure loads of the crossed-screw configuration were greater than those of the parallel screw configuration. Clinically, this provides the surgeon more options for stabilizing a subtrochanteric femur fracture. This decision may be made intra-operatively if necessary, facilitating fracture fixation and providing a stable construct.
