[Pathophysiology of osteoporosis].
3-dimensional analyses of trabecular bone structure in osteoporosis reveal that perforations of individual trabeculae are common. They result in a reduction of the stability of the trabecular network by inducing mechanically incompetent trabeculae. Reparative mechanisms, like microcallus formations, may also lead to errors when measuring trabecular bone density.
