Biomechanical Consequences of Nail Insertion Point and Anterior Cortical Perforation for Antegrade Femoral Nailing

Figure 5

Stiffness and stress results: (a) axial stiffness, (b) coronal 3-point bending stiffness, (c) sagittal 3-point bending stiffness, (d) torsional stiffness, (e) proximal stress, and (f) distal stress. INT: intact femur; ANT: anterior nail insertion without perforation; NEU: neutral nail insertion without perforation; POS: posterior nail insertion without perforation; POS-P: posterior nail insertion with perforation. Each bar represents the . Symbols indicate all statistical differences detected for pairwise comparisons ().
