TLDR
Compared with the bone of adults, that of children had a lower modulus of elasticity, a lower bending strength, and a lower ash content, but the children's bone deflected more and absorbed more energy before breaking.Abstract:
Specimens of femoral cortical bone from eighteen subjects between two and forty-eight years old were loaded in bending. Compared with the bone of adults, that of children had a lower modulus of elasticity, a lower bending strength, and a lower ash content. However, the children's bone deflected more and absorbed more energy before breaking. It also tended to absorb more energy after fracture had started. The typical greenstick fracture surface of many specimens of children's bone requires more energy for its production than the relatively smooth surface of adult specimens.read more

Skeletal Tissue Mechanics
TL;DR: This poster presents a probabilistic procedure for estimating the mechanical properties of bone based on known mechanisms, including compressive forces, compressive strength, and the compressive properties of Bone.

The mechanical behaviour of cancellous bone
TL;DR: The results of this previous study are applied to cancellous bone in an attempt to further understand its mechanical behaviour and the results agree reasonably well with experimental data available in the literature.

Age-related changes in the tensile properties of cortical bone. The relative importance of changes in porosity, mineralization, and microstructure.
TL;DR: The quantitative changes in aging bone tissue, rather than the qualitative changes, influence the mechanical competence of the bone.
Journal ArticleDOI
Predicting the compressive mechanical behavior of bone
TL;DR: The results indicate that the mathematical dependency of bone compressive mechanical properties on composition is closely dependent upon the density and mineral content range examined and, in terms of a single compositional measure, is best predicted by apparent ash density expressed as a power function.

The elastic moduli of human subchondral, trabecular, and cortical bone tissue and the size-dependency of cortical bone modulus
TL;DR: The surface area to volume ratio proved to be a key variable to explain the size-dependency of the modulus and the values decreased as the specimens became smaller, whereas for relatively large specimens, the values remained fairly constant.

TL;DR: In this article, the relationship between the ash content of rabbits' metatarsals and their modulus of elasticity, static strength, work-to-failure and impact strength was determined.

The ultimate properties of bone tissue: The effects of yielding
TL;DR: An elastic perfectly plastic mathematical model for the behavior of bone tissue is presented in an attempt to reconcile previous discrepancies in the literature in the calculated ultimate tensile strength from bending and tensile tests.

Traumatic bowing of the forearm in children.
TL;DR: Reduction under general anesthesia corrected the bowing of both radius and ulna in one patient, while manipulative reduction decreased the radial and ulnar deformities in a second patient.
