Bone fractures and treatments

The bones of the lower leg were examined from the viewpoint of strength of materials. The area, the moment of inertia of area and the polar moment of inertia of area of the cross-section at the middle of the lower leg bones were calculated. The resistance of the bone against the normal force, against the bending moment and against the torsion can be shown by these properties of the cross-section. The properties of the shape of the bones do not correlate with the age of the specimen. The sexual dimorphism is clear. The fibula is very much weaker than the tibia. The index of cross-section has no direct correlation with the strength of bones nor with the curvature of tibia shaft.
