Why does trabecular bone fracture more readily under torsional stress than cortical bone, despite both experiencing similar applied torque?

💡 Explanation

Trabecular bone fractures more easily under torsion due to its anisotropic material properties, where its lower density and less organized structure provide weaker resistance to shear stresses compared to cortical bone's greater homogeneity; because of these weaker shear properties, the torsional load causes failure. Therefore, trabecular bone is weaker under torsion rather than the alternative properties.
