Osteoporosis and Fracture Risk in Patients with Type 2 Diabetes Mellitus

Type 2 diabetes mellitus (T2DM) is associated with an increased risk of fragility fractures compared to the general population. The pathogenesis of the elevated fracture risk is multifactorial and still largely elusive. In contrast to primary osteoporosis, in T2DM the bone mineral density (BMD) is increased compared to controls, suggesting that specific alterations in bone quality occur in diabetic patients. Even more, the specific increase in BMD observed in these patients impairs at least in part both the classical diagnosis of osteoporosis by dual-energy X-ray absorptiometry (DXA) and the current fracture risk estimation by FRAX (fracture risk assessment tool). Trabecular bone score (TBS) and TBS-adjusted FRAX could improve fracture risk estimation in patients with T2DM but improved tools are needed in the future as well as specific risk stratification criteria. Decreases in the fracture risk of patients with T2DM can be obtained by optimal diabetes control and standard treatment of osteoporosis (most drugs appear to have similar efficacy in patients with T2DM and primary osteoporosis).
