In this study, in order to clarify the limitations of most commonly used mechanical characterization techniques, both three point (3P) and torsional testing devices which are mobile and low-cost, have been designed and set up to measure mechanical properties of femur tissues. In order to evaluate efficiency and compatibility of testing systems, femur tissues have been mechanically tested and characterized. The low-cost mobile test systems and their calculation methods presented in the literature were defined and compared with the experimental results. It is determined that the values of maximum stress, modulus of elasticity, shear stress and shear modulus are well compatible with the literature values in +/- 10% error band. In the study advantage and disadvantages of the each method are discussed as the application hints about specimen preparation, data processing, stability, device selection etc. According to the fracture types, it is concluded that the 3P Bending methods can simulate the butterfly, compound, crush, greenstick and incomplete fracture types that take place by bending moments caused to tensile stresses. On the other hand torsional testing method can simulate spiral, high-energy and other kinds of femoral shaft fractures.
