Auntie Wang is 55 years old and has been menopausal for 3 years. Before that, she had been in good health and went to the community square every day to work out. Some time ago, the back of the waist began to hurt. Auntie Wang did not care, thought it was the chores to do more tired, rest a few days on the good. But I did not want to start back pain, and then slowly the whole body bones began to hurt, standing for a long time more obvious. Auntie Wang rushed to the hospital to check, took a film. See the medical record diagnosis column big five words: osteoporosis, Wang aunt a little blind. Usually eat well, sleep well, diligent exercise, how osteoporosis it? What is the problem of osteoporosis? What are the dangers and how to prevent and treat it? In the next period of time, I will talk to you about the topic of osteoporosis. Osteoporosis is not a new word, every day on TV put a lot of advertising claim to be able to treat osteoporosis. So what exactly is osteoporosis? In 2001, the National Institutes of Health (NIH) proposed that osteoporosis is a disease of the skeletal system characterized by a decrease in bone strength and an increased risk of fracture. According to the WHO definition, osteoporosis (OP) is a systemic bone disease characterized by low bone mass and destruction of bone microarchitecture, leading to increased bone fragility and susceptibility to fracture. There are several key words here, low bone mass and destruction of bone microarchitecture: these are the pathological manifestations of osteoporosis; increased bone fragility and susceptibility to fracture: these are the serious consequences of osteoporosis. Bone is the scaffolding of the human body, playing an important role in support and protection. Imagine if the scaffold is loose, once encountered some blow, even if it is very slight, the consequences will be very serious. The bones of a normal person are built up by tiny bone trabeculae, with various cells hiding in the pores. In osteoporosis, the number and quality of trabeculae in the bones are greatly reduced, which visually means that the bones are loose. The most vulnerable areas of the body are the spine, hip and distal forearm. First, these areas are mainly cancellous bones and are most vulnerable when osteoporosis occurs; second, these areas are weight-bearing and injury-prone and are susceptible to injury. Therefore, the three most common osteoporotic fractures in clinical practice are the spine, hip, and distal radius.
