In 1999 a paper published in Science suggested that 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins) increased bone formation in rodents by effects on a potent bone forming cytokine bone morphogenetic protein-2 (BMP-2).1 Subsequent studies have suggested that statins increase bone mineral density (BMD) in humans2 and have investigated whether statin use is associated with reduced fracture risk. The fracture risk studies include four casecontrol studies, five cohort studies in which fracture end points where documented, and the post hoc analysis of the effect of statins on fracture in two cardiovascular outcome studies. To date there are no prospective
