After orthopedic surgery, patients need to rest in bed and reduce their activities, so gastrointestinal motility is slowed down and constipation is likely to occur. Therefore, in the early post-surgery period, patients are instructed to take coarse fiber food orally to promote gastrointestinal motility and prevent constipation, and to eat more light food such as cabbage, cabbage, celery and other coarse fiber food. In the middle and late stages of surgery, the fracture site needs bone scabs to grow, so the patient should be told to eat more calcium-rich foods such as sea rice, shellfish, or more soybeans, lean meat, dairy products, soy products, etc., to help the fracture site heal as soon as possible.
