[Bone micro-structural changes following osteoporotic drug treatment].

Osteoporotic drugs improve bone mechanical integrity by increasing bone mass and also by improving bone structure and quality, where controlling bone metabolism. Changes in trabecular microstructure can be detected since early period after starting drug treatment. Effects on bone metabolism of anti-resorptive agent of bisphosphonates are totally opposite from those of anabolic agent of teriparatide, however these different drug treatments results in the improvement of trabecular microstructure as well.
