In vitamin D–deficient sample, the crack takes a tortuous breaking path across the osteons with no crack bridging. These 3D reconstructions of crack paths show in the normal bone (left) pronounced crack deflection by splitting along the interfaces of the osteons accompanied by the formation of crack bridges. ![]()
