[Osteomalacia]

Osteomalacia is a metabolic bone disease caused by deficiency of vitamin D or its active metabolites. Despite a very typical X-ray picture and laboratory finding, it is very poorly diagnosed in the field and thus not treated. This may be due to its atypical clinical picture and also because this disease is frequently omitted in diagnostic considerations. After assessment of the diagnosis the vitamin D treatment or treatment with its metabolites is rapid and successful moreover these substances have also an immunomodulating and anabolic effect.
