Findings of reduced bone mineral density and osteoporosis in hemophilia patients are gradually increasing and will certainly increase with successful treatment and increasing life expectancy. Older, not very numerous studies are being replaced by large meta-analyses showing significant reduction of bone mineral density in hemophiliacs. However, it is not only the effect of increasing age that is being demonstrated, but also the direct and indirect pathobiochemical links between coagulation factor deficiency and the effect of their therapeutic administration on bone tissue metabolism. A crucial role is played by the influence of the RANK/RANKL/OPG system and the direct binding of factor VIII or IX and their complex with von Willebrand factor to its components. The influence of different therapeutic pathways in the treatment of hemophiliacs is not negligible.
