In this study, the investigators would like to analyze the bone mineral density (BMD) , bone turnover makers, and fracture prevention effects of denosumab in Japanese patients under clinical practice. The participants are treated in the investigators hospital, who are under severe osteoporotic condition.
The main objective of this study is to investigate effects of denosumab. The researchers also investigate the effects of Effects of previous osteoporotic therapy to denosumab treatment. In this study, the investigators analyse the determinants of subsequent BMD increase and fracture preventing effect by teriparatide.
Registry criteria: Patients treated in the investigators hospital using denosumab. Enrolled patients are severe osteoporosis; more than two previous osteoporotic fractures, low BMD (< young adult mean 65%).
Interventions: blood analyses and dual-energy X-ray absorptiometry (DXA) every 4 months Informed consent: Written informed consent will be obtained. Sample size: Five-hundreds participants
