Biomechanical analysis of the fractured femur. Torsional testing was applied to the fractured and unfractured femur of each animal. Maximum torque [Nmm] and angle of failure [°] were determined and used for calculation of torsional stiffness [Nmm/°]. The ratio of fractured femur/non-fractured femur [%] was calculated. Wild type: n = 8, hTNFtg: n = 6, hTNFtg + TNFi: n = 7, * p < 0.05; dashed line: p < 0.1, tendency.
