Varies from person to person 1. Patients with less severe fractures can ingest food via mouth early after fixation; 2. Patients with more severe fractures show multiple fractures, or open fractures with more bleeding, or with more severe soft tissue contusions. The patient’s consumption increases significantly and may also affect gastrointestinal function. Consider giving intravenous nutrition therapy, which is beneficial to the healing of trauma and control of complications, and gradually transition to transoral feeding after the condition improves and stabilizes, and reduce the dosage of parenteral nutrition preparation until it is finally discontinued; 3. 4.After fracture and other trauma fixation, the repair and growth of tissues will consume more calcium, magnesium, zinc and other minerals and trace elements, so attention should be paid to giving supplements from veins or food. There are differences between different periods. The early stage, within 2-3 weeks after fracture, is the period of hematoma mechanization. According to Chinese medicine, “if the stasis does not go away, the bone cannot be born”. The diet should focus on reducing the swelling and dispersing the stasis, avoiding large supplements. Western medicine believes that in the early stage of fracture, the body and physical strength are under attack, and most of them go through surgery, so the patient usually has poor appetite and impaired gastrointestinal function. During this period, it is best to give priority to light and easy digestion, such as vegetables, milk, fish soup, lean meat porridge, etc. Avoid smoking, alcohol, spicy and oily food, etc. The middle period, 12-24 weeks after fracture, is the period of bone scab formation. At this time, the patient has already adapted to the situation after the fracture physiologically and mentally, the pain caused by the fracture has been relieved, most of the stasis and swelling have disappeared, and the appetite and gastrointestinal function have been restored. The diet should be changed from light to appropriate high nutrition. Mainly protein, calcium and vitamin rich foods such as bone broth, dairy products, soy products, C meat, animal offal, and vegetable foods such as mushrooms and black fungus. However, care should still be taken not to be too greasy or to consume too much and cause obesity or other discomfort. The late stage, several months-2 years after the fracture, is the period of bone scab plasticity. During this period, there are no special dietary contraindications, and an ordinary daily diet is sufficient. In the case of middle-aged and elderly people with combined osteoporosis, attention should also be paid to the intake of calcium.
