Osteoporosis is a systemic bone disease characterized by a decrease in bone mass and microstructural degeneration of bone tissue, a constant decrease in the ratio of bone mineral components and bone matrix, a thinning of the bone cortex, and a decrease in the number of bone trabeculae, resulting in an increase in bone fragility and a tendency to fracture. Under normal conditions, the whole skeletal system of the body is always in a dynamic balance between bone destruction and bone formation. The rate of bone turnover in the body is significantly accelerated, and the rate of bone resorption exceeds the rate of bone formation, resulting in bone loss, decreased bone density, and increased bone fragility, leading to the occurrence of osteoporosis. The main manifestations of osteoporosis are the decrease in bone mass, the increase in bone fragility, the appearance of generalized bone pain, joint pain, and the high risk of osteoporotic fractures in the elderly.
