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

Figure 4

Rosette locations: (a) proximal rosette, (b) distal rosette, and (c) close-up of rosette with linear strain gages , , and . Wire leads are not shown so rosettes are clearly visible. Only a typical POS-P specimen (i.e., with perforation) is shown, but even for INT, ANT, NEU, and POS groups (i.e., without perforation), the rosettes were at the same corresponding locations to make direct comparisons of bone stress possible.
