骨骼是人体的支架,人之所以能行动自如,是由于骨骼、肌肉、神经等共同协作的结果。随着年龄的增长,骨骼中的有机成分,如骨胶原、骨粘蛋白等逐渐减少,无机盐成分逐渐增加,因而骨骼变脆,容易发生骨折。据研究,40岁以后逐渐出现骨质疏松及骨质萎缩,骨密度减少。70岁～80岁的老人,骨密度相当于青年时期的50％左右。所以,45岁以后,骨、关节的疾病逐渐增多,例如骨质疏松症、老年人骨折、老年性关节炎、肩周炎、颈椎病等。骨质疏松症,是一种全身代谢性疾病,以骨质减少、骨的微观结构退化、骨的脆性
Bone is the body’s support, people have been able to move freely, due to the bones, muscles, nerves and other collaborative results. As the age increases, the organic components in the bone, such as collagen and osteocalcin, gradually decrease, and the inorganic salt component increases gradually. As a result, the bone becomes brittle and fractures easily occur. According to the study, after the age of 40, osteoporosis and bone atrophy gradually appeared and the bone density decreased. 70 years old to 80 years old, bone mineral density equivalent to about 50% of youth. Therefore, after the age of 45, bone and joint diseases gradually increased, such as osteoporosis, fractures of the elderly, senile arthritis, frozen shoulder, cervical spondylosis and so on. Osteoporosis is a systemic metabolic disease characterized by osteopenia, deterioration of the microstructure of the bone, fragility of the bone
