The basic principle of diet supply for orthopedic patients is to meet the energy and water needs of patients. To this end, attention should be paid to the combination of main and side dishes, meat and vegetable blends, and fancy varieties. In addition, the patient’s usual eating habits should be taken care of. 1, early fracture: newly injured patients, there will be changes such as loss of appetite and reduction in the amount of food eaten, with the passage of time, the patient’s appetite will gradually recover. Therefore, attention should be paid to correcting the loss of water and salt. It is advisable to use low-fat, high vitamin, high sodium, high iron, more water content, light taste, easy to digest semi-liquid diet. 4~5 meals per day. For lightly injured patients with fractures of the extremities, ordinary meals are available, with 3 meals per day and additional meals of vitamin AD milk or fortified calcium yogurt in the afternoon. 2.Middle fracture: choose foods such as green vegetables, radish, broth, thin rice (can add vegetable juice, minced meat, drugs, etc.), lotus root powder; supplemented with fruits after meals, such as bananas, apples, oranges and the like. The amount of food should not be too much at a time, it is advisable to eat less and more meals. Do not rush to take tonic products, avoid fatty, oily and greasy too much, as well as cold, raw and cold, coarse and hard food to prevent damage to the spleen and stomach. With wound infection, fever, avoid eating meat and spicy food, such as chicken, carp, beef, sheep and dog meat, shrimp, crab and seafood; onion, pepper, leek, cauliflower and wine are not suitable for consumption. 3, late fracture: can give high protein, high fat, high sugar, high calorie, high vitamin, high calcium, high zinc, high copper diet, in order to facilitate fracture healing and the replenishment of the body consumption. The following should be noted in the diet: 1. Avoid foods that are too cold to reduce the stimulation of the gastrointestinal tract and prevent diarrhea caused by excessive intestinal peristalsis and inflammation of the gastrointestinal tract. 2. For bedridden patients with fractures of the spine, pelvis and lower extremities, it is advisable to eat more vegetables containing more fiber and to eat foods that promote defecation, such as bananas and honey. If necessary, take laxative drugs. 3.Bedridden patients are also prone to urinary tract infection and urinary tract stones, so it is advisable to drink more water diuretic, more than 2000ML per day. 4.For patients who cannot eat by themselves due to upper limb fracture, they should be fed regularly and regularly, pay attention to the slow feeding speed and swallow after full chewing, so as to facilitate digestion and absorption. 5, the elderly fractures due to osteoporosis, in the treatment of fractures, must be actively supplemented with calcium, but also vitamin D, to assist absorption. For those who cannot go outdoors in the sun, cod liver oil drops or vitamin D tablets or vitamin D fortified milk or yogurt should be supplemented. 6. For fracture patients with diabetes, kidney disease or liver disease, dietary principles must be taken into account, otherwise it is not conducive to the recovery of overall health. 7.A special reminder: fracture patients should not smoke, as smoking can affect fracture healing.
