Collagen fiber organization is related to mechanical properties and remodeling in equine bone. a comparsion of two methods
TL;DR: It was concluded that, in the equine cannon bone, longitudinal collage fiber orientation is regionally variable, contributes to increased modulus and strength but not fatigue life, and is reduced by osteonal remodeling.

Calcium buffering is required to maintain bone stiffness in saline solution
M. B. Gustafson,R. B. Martin,V. A. Gibson,D.H. Storms,Susan M. Stover,J. C. Gibeling,L. V. Griffin +6 more
TL;DR: This work determined whether mineral dissolution due to prolonged testing or storage of bone specimens in normal saline would alter their elastic modulus, which significantly diminished 2.4%, whereas the modulus of those soaked in calcium-buffered saline did not change significantly.

Osteon pullout in the equine third metacarpal bone: effects of ex vivo fatigue
L. P. Hiller,Susan M. Stover,V. A. Gibson,J. C. Gibeling,C. S. Prater,Scott J. Hazelwood,Oscar C. Yeh,R. B. Martin +7 more
TL;DR: The data suggest that tensile fatigue loading of cortical bone eventually introduces damage that results in osteonal debonding and pullout, which is also associated with increased fatigue life via mechanisms that are not yet clear.

Osteonal effects on elastic modulus and fatigue life in equine bone.
TL;DR: The hypothesis that remodeling extends load-controlled fatigue life both through the creation of osteonal barriers to microdamage propagation and modulus reduction and the relationships between these variables, elastic modulus (E), and the logarithm of fatigue life (logN(F)).

Residual strength of equine bone is not reduced by intense fatigue loading: Implications for stress fracture
TL;DR: Loading equivalent to a lifetime of racing does not significantly weaken equine cortical bone ex vivo, suggesting that the biological repair of fatigue damage can actually contribute to stress fracture if pressed too far.
