骨质疏松症是一种全身性骨疾病,其特点是骨量减少和骨组织的微细结构破坏导致骨脆性增加,骨强度降低而容易发生骨折。我国部分地区统计资料表明由于骨质疏松导致骨折的发生率达7.31%～12.2%。目前临床上主要依靠DEXA测定骨密度来诊断骨质疏松,被称为金标准。但将近一半的脆性骨折发生在骨量减少中。在一项671例绝经后妇女的前瞻性研究中,发 Osteoporosis is a systemic bone disease characterized by reduced bone mass and destruction of the fine structure of bone tissue leading to increased bone fragility and reduced bone strength and prone to fractures. Statistics in some parts of China show that the incidence of fractures due to osteoporosis reached 7.31% ~ 12.2%. Currently clinically rely mainly on DEXA measurement of bone mineral density to diagnose osteoporosis, known as the gold standard. But nearly half of the fractures occur in bone loss. In a prospective study of 671 postmenopausal women,
