Bone Mechanics Copy

TRUE or FALSE: If a bone has trabecula aligned mostly vertically (up and down), then it is more likely to be able to resist compression forces which are also vertical.

True
False

If the same forces is applied to each of the following three bones, which one is most likely to break more easily, given it’s geometry and make-up?

A bone with a diameter of 5 mm, a thin cortical shell surrounding normal density cancellous bone
A bone with a diameter of 3 mm, a thick cortical shell surrounding normal density cancellous bone
A bone with a diameter of 3mm, a normal cortical shell surrounding low density cancellous bone

Which is the correct pair of fracture forces and patterns?

Bending force: fracture on convex surface
Torsion fracture: produced by a force parallel to the bone
Compressive fractures: produced by forces twisting the bones
