骨质疏松症(osteoporosis,OP)是一种以骨量低下,骨微结构损坏,导致骨脆性增加,易发生骨折为特征的全身性骨病(世界卫生组织,WHO)。2001年美国国立卫生研究院(NIH)提出骨质疏松症是以骨强度下降、骨折风险性增加为特征的骨骼系统疾病。骨质疏松症分为原发性和继发性二大类。原发性骨质疏松症又分为绝经后骨质疏松症(Ⅰ型)、老年骨质疏松症(Ⅱ)和特发性骨质疏松3类。特发性骨质疏松主要发生在青少年,病因尚不明。继发性骨质
Osteoporosis (OP) is a type of systemic bone disease characterized by low bone mass, damaged microstructure of the bone, increased bone fragility and fractures (World Health Organization, WHO). In 2001, the National Institutes of Health (NIH) proposed that osteoporosis is a skeletal system disorder characterized by decreased bone strength and increased risk of fracture. Osteoporosis is divided into two major categories of primary and secondary. Primary osteoporosis is divided into postmenopausal osteoporosis (type Ⅰ), senile osteoporosis (Ⅱ) and idiopathic osteoporosis. Idiopathic osteoporosis occurs mainly in adolescents, the etiology is unknown. Secondary bone
