Determination of mineral-organic bonding effectiveness in bone-theoretical considerations

Abstract: It is postulated that the effectiveness of bonding between the mineral and organic phases could be an important influence on the behavior of bone with respect to its mechanical properties, metabolic activity, and aging effects associated with these factors. Changes in bonding effectiveness might also be related to the etiology of osteoporosis. If this hypothesis is correct, it would be of interest to determine the amount of debonding present in bone. An analysis that employs both macromechanical and micromecha… Show more

“…Bone itself has a broad spectrum of mechanical properties, depending on its type, [52][53][54][55][56] humidity, 57 mineral content, [58][59][60] density, 58,61 porosity, 58 collagen fiber orientation, 58,62 and interfacial bonding between constituents. 14,15 The reinforcement and toughening mechanisms of bone [63][64][65] lie in its complex hierarchical structure, as well as its inorganic and organic constituents. In addition, the mineral phase is not a discrete aggregation of the calcium phosphate crystals.…”

“…The preferential orientation of bone minerals and the interfacial bonding between the mineral and organic constituents play an important role in determining the overall mechanical behavior of bone. [13][14][15] Furthermore, the assembly of the minerals and matrix is accomplished in aqueous media at ambient conditions.…”

“…SAXS is well suited to determine the size, shape and orientation of the mineral crystals within the collagen matrix, since the large electron density di erence between mineral and organic matrix leads to a strong SAXS signal. It is known that in the microstructure of bone, the mineral crystals have a large aspect ratio and align along collagen ÿbers with a preferred orientation parallel to the longitudinal axis of the bone (Bundy, 1985). Non-hydrostatic thermodynamics predicted that crystal growth is parallel to the principal stress directions and suggested the possibility that mineral orientations in biological tissues can be in uenced by functional loading (Williams, 1989).…”

“…The initial studies assumed bone as a unidirectional reinforced mineral-collagen composite [18,26,38]. This model was later modified considering the orientation distribution of mineral crystals [15,39,40]. However, unlike fiber-reinforced engineering composites, there are mixed views about the reinforcing component in bone at the nanoscale level.…”
