Biomechanical Comparison of Three Different Intramedullary Nails for Fixation of Unstable Basicervical Intertrochanteric Fractures of the Proximal Femur: Experimental Studies

Figure 3

Illustration showing the test setup and 3D motion tracking system (stereophotogrammetry) for the proximal fragment including attachment of black pen markers. Two cameras were placed at 30 degrees to the center of the specimen to establish the experimental environment for stereophotogrammetry.
