Lecture 1: “Potential killer” – osteoporosis Hello, elderly people! Today I would like to introduce you to a disease called “potential killer” – osteoporosis. I remember that last year, a female patient was transferred to my ward from the Department of Orthopedics, Zhang Lao, who was said to have stayed in the Department of Surgery for nearly three months. She fell off the chair accidentally and fractured her left femoral neck, so she returned to the hospital and could only be bedridden. But less than a week later, I met her again in the emergency room, and her family told me helplessly that Zhang had fractured her right forearm at home when she reached for something and propped her hand on the ground. Think about how terrible it is when a person has three fractured limbs. This is a patient with obvious fractures, but some fractures are not obvious, there was an elderly female patient, early dementia, expression is unclear, but every night shouting chest and back pain, do not want to go to bed, the family is no peace at night, the daughter is very filial, take her everywhere to see a doctor, what ECG, cardiac ultrasound, chest X-ray, CT have been done, eat a lot of medicine does not work, but we Just feel the spine you can find the thoracic vertebrae protrude backwards, in a look at the lateral thoracic spine film, found two thoracic vertebrae fracture, that is already three months ago, still do not know when the fracture, neither fell nor hit, this is the characteristics of the elderly vertebral fracture, often without a clear history of trauma, sometimes coughing and lifting heavy objects will also vertebral fracture, after the osteoporosis treatment effect is very good, the The family can also sleep peacefully. Do you think it is normal for older people to be shorter or to have a hunched back? Is it normal to have back pain? Some people are in so much pain that they want to jump off a building, but their families and even the people themselves do not realize that these people have been suffering from osteoporosis for a long time before the fracture, before the hunchback, before the pain, and it is this “potential killer” that makes people’s quality of life decline. The question is whether you are aware of the existence of this disease. Unlike hypertension, which can start with dizziness, headache and unstable walking, and can lead to cerebral hemorrhage and cerebral infarction if left untreated, osteoporosis can be asymptomatic for a long time and can lead to serious complications – fractures. This can cause a lot of distress to yourself and your family. To know why some people fall several times without problems? And some people break their bones when they fall? First of all, let’s introduce our bones. Our bones are living tissues, from our birth, growth, development and maturity to aging throughout our life, old bones are constantly removed and new bones are formed, experiencing a journey from bone growth and improvement of bone quality to bone loss and bone deterioration.
