The risk of having a new vertebral fracture decreases between 65% to 69%, and the increase of bone mass ranges between 9% to 11%. This is similar to the range reached by bisphosphonates as alendronate and risedronate at 7 years of treatment. Moreover, recent studies have shown that a secuential treatment with bisphosphonates and teriparatide the increase of bone mass reaches 23,6%. The prescription of teriparatide in Spain is only for postmenopausal establish osteoporosis, that means with fractures.
