Skeletal fragility definition.

Strategies to reduce fracture risk must be based on the understanding of the mechanisms that underline the increased incidence of fractures with age and with bone diseases that reduce bone stock. There is evidence that in addition to bone minerals density, other factors influence bone strength. This study reviews the biomechanical aspects of age-related fractures, including the interacting roles of traumatic loading and bone strength, and the factors that determine the resistances of bones to fracture.

Bone fragility: current reviews and clinical features.

Bone strength is determined by a number of important factors, including bone mass and bone shape. A reduction in bone strength is clearly related to fracture. Bone fragility results from a reduction in bone mass and density.
