Indications for long-term anticoagulation are expanding. Osteoporosis is a complication which can develop after prolonged treatment with unfractionated heparin and is probably multifactorial. Data on osteoporosis associated with low-molecular-weight heparins (LMWH) are contradictory. Vitamin K participates in bone metabolism and since oral anticoagulants antagonize vitamin K, their use may also increase the risk of osteoporosis.
