The role of certain treatments in the development of bone fragility is well known. Since the 2000s, several studies, conducted in patients on long-term anticoagulants have suggested the involvement of vitamin K antagonist (VKA) in the occurrence of osteoporotic fractures. Since their launch in 2008, the new oral anticoagulants (NOACs) have been widely used. Compared to VKA, this drugs' class is associated with a lower fracture risk. Therefore, the presence of risk factors for fracture should be considered when prescribing long-term anticoagulants. In this line, the NOACs seem to be an interesting alternative for patients at risk of fracture requiring a long-term anticoagulation. Nevertheless, certain aspects remain to be clarified.
