Fractures can cause great pain and anguish to the elderly and their relatives, and they often leave behind functional impairment after fractures. The most common fall injury among the elderly is periprosthetic fracture, which is difficult to treat, takes a long time in bed and is prone to serious complications, and foreign statistics show that the mortality rate of periprosthetic fracture is as high as 20%. In the cold winter, the elderly should not only prevent cold and disease, but also prevent falls, specifically from the following aspects: 1, strengthen nutrition and exercise to reduce osteoporosis: the elderly should eat more food rich in protein and vitamin D. Regular physical exercise within their reach, winter exercise is best combined with “sunbathing”, such as outdoor walking, sun exposure, to promote the synthesis of more vitamin D in the body to help calcium absorption. Under the guidance of doctors, according to the bone density test, calcium, active vitamin D, bisphosphonates, Chinese medicine and other drugs can be applied to slow down bone loss, improve bone mineralization, inhibit bone resorption, improve bone density, enhance muscle strength and balance of the elderly, and reduce the risk of falling. 2.Strengthen the care for the elderly: Try not to let the elderly live alone. Older seniors who have outings should be accompanied by someone, and crutches can be used as appropriate. In winter, the indoor temperature should be kept above 10 degrees Celsius, so that the elderly can wear less clothes and move around lightly (the popular “thermal underwear” is more suitable for the elderly). Winter shoes should also be selected, not only to keep warm, but also to prevent slippery, hard plastic soles and other shoes are the most inappropriate. The ground of the elderly living place (especially the bathroom) should be kept dry to prevent water accumulation and icing. 3, strengthen the control of weight, avoid excessive obesity, timely treatment of related diseases: family members and children should pay attention to the characteristics of certain drugs commonly used by the elderly, follow the instructions and medical advice, as far as possible to reduce the side effects of drugs, such as antihypertensive drugs, can cause postural hypotension, which can easily lead to falls. In addition, the elderly drink too much alcohol, or too emotional, but also easy to lead to body balance disorders, need to be controlled. Of course, once the elderly have fallen, pick up and carefully ask and check whether there are any injuries. If the pain is heavy, local swelling, can not move, should be suspected of fracture or dislocation, should be immediately sent to the hospital to check, confirm the diagnosis, treatment, to avoid more serious consequences.
