Summary

The aim of this study is to analyze the hereditary determinism of bone microarchitecture measured at the distal radius and distal tibia from a case control-study of mother-daughter pairs.

Detailed description

Many factors influence the risk of osteoporosis but one of the most important is a positive family history, emphasizing the importance of genetics in the pathogenesis of osteoporosis. Till now, most genetic studies in osteoporosis have focused on the phenotype of BMD. However, areal BMD (bone quantity per unit bone area measured) does not provide information regarding bone distribution (between cortical and cancellous compartments) or bone microarchitecture (trabecular number, thickness, spacing and distribution) and cortical (thickness, porosity). We are planning to analyze the hereditary determinism of bone microarchitecture assessed non invasively with HR pQCT at the distal radius and the distal tibia in a case-control study with fractured and not fractured mothers and their daughters. Additionally, the role of the bone turnover, hormones involved in regulating bone metabolism , bone geometry measured at the proximal femur and bone strength estimated by finite element analysis (μFE)in the hereditary determinism of bone fragility will be analyzed.
