骨质疏松症是一种以骨量低下,骨微结构损坏而导致骨脆性增加,易发生骨折为特征的全身性骨病(世界卫生组织,WHO)。美国国立卫生院(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性疾病,骨强度反应骨骼的两个主要方面,即骨矿密度和骨质量。骨质疏松分为原发性和继发性两大类,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型)和特发性骨质疏松3类。老年骨质疏松症一般指老年人70岁后发生的骨质疏松。骨质疏松的严重后果是发生骨质疏松性骨折,即在受到轻微创伤或日常活动中即可发生的骨折。骨质疏松骨折的常见部位是脊柱、髋部和前臂远端。骨质疏松性骨折的危害很大,病残率和死亡率高。骨质疏松骨折是可防、可治的。尽早预防可以避免骨质疏松及其骨折的发生。
