abstract：:The incidence of fractures increases with age. This is partly due to extraosseous factors and partly to the increased fragility of the bone material itself. Ageing adversely affects the "quality" of human bone material, its elastic and ultimate properties. The hypothesis here is that these effects are caused by factor...
