Holographic measurements of fresh- and dry-bone elasticity

To compare the elasticity of bones covered with soft tissue and the elasticity of defleshed and dried bones we used sampling screws to make the surface movements of the bones visible through the soft tissue. We compared fresh and dry European moose skulls with antlers before and after skinning. External forces were focused on the skull bones through the antlers and on the metatarsal bones through the distal epiphysis. A high correlation in fringe orientation was observed in the case of thick skull bone structures with rigid interdigited sutures. We also compared compression dynamics of fresh and dry moose antler cubes.
