The elderly need to rest in bed when they have a back fracture, and the reduced activity will easily lead to slowed gastrointestinal motility and constipation. In the early stage, the elderly should be told to eat more light foods, such as cabbage, spinach, celery and other coarse fiber foods, which help the elderly digest and can prevent constipation. In the middle and late stages of a lumbar fracture, the fracture site needs bone scabs to grow and increase local stability. The elderly should be instructed to eat more food with high calcium content, they can drink more carp stewed tofu soup, pig trotters stewed soybean soup, eat more sea rice, shellfish, and also eat more dairy products, soybean products and other foods, all of which help the fracture recover as soon as possible.
