Bone fracture is the most common effect in osteoporosis. one the reason is the impact of osteoporosis on the density of the cortical bone. So I'm looking for the role of the density disorder which is caused by osteoporosis in bone fracture.
You will find below the reference of an excellent review, very complete, that describes the link between the mechanisms leading to the reduction of bone mass, bone fragility and the occurrence of fractures, with data on both the trabecular and cortical bone tissues.
