There are many causes of fractures such as: car accidents, falls, impacts, etc. Many carelessness in life may also cause fractures, so what should I do if I break a bone? The ultimate goal of treating fractures is to maximize the injured limb. Maximize the restoration of its function. Therefore. In fracture treatment, the three basic principles of its reset, fixation and functional exercise are very important. Displacement: It is the process of restoring the fracture end that has been displaced after the fracture to its normal or near normal position in order to regain the brace role of the bone. The methods of repositioning include closed repositioning, surgical repositioning, and external fixation brace repositioning. Fixation: After the fracture is repositioned, it is prone to re-displacement because of its instability, so different methods should be used to fix it in a satisfactory position to make it heal gradually. Commonly used fixation methods are: small splints, plaster bandages, external fixation braces, traction brake fixation, etc. These are called external fixation. If the surgical incision on the plate, steel pins, intramedullary pins, screws, etc., it is called internal fixation. Functional exercise: through the muscle contraction of the injured limb, increase the blood circulation of the tissue around the fracture, promote fracture healing, prevent muscle atrophy, through active or passive activities The diet of the fracture should follow the following points: 1, avoid blindly supplementing calcium Calcium is an important raw material for the composition of the bones, some people think that after the fracture more calcium can accelerate the healing of broken bones. But scientific research has found that increasing calcium intake does not accelerate the healing of broken bones, and for patients with long-term bedridden fractures, there is a potential risk of increased blood calcium, accompanied by a decrease in blood phosphorus. This is the result of prolonged bed rest, which inhibits the absorption and utilization of calcium on the one hand, and increases the reabsorption of calcium by the renal tubules on the other. Therefore, for patients with fractures, there is no lack of calcium in the body, as long as the condition and according to the doctor’s orders, strengthen the functional exercise and early activity, it can promote the absorption and utilization of calcium in the bone and accelerate the healing of broken bone. Especially for patients who are bedridden after a fracture, blindly supplementing calcium is not beneficial and may be harmful. Some people think that eating more meat and bones after a fracture can make the fracture heal early. In fact, modern medicine has proven many times that eating meat and bones after a fracture does not lead to early healing, but rather delays the healing time of the fracture. The reason for this is that the regeneration of bone after injury mainly depends on the role of periosteum and bone marrow, which can only function better under the condition of increasing collagen, while the ingredients of meat and bones are mainly phosphorus and calcium. If a large amount is ingested after a fracture, it will contribute to the increase of inorganic components in the bone, resulting in an imbalance in the ratio of organic matter in the bone, so it will have a hindering effect on the early healing of the fracture. But fresh meat and bone soup tastes delicious and stimulates the appetite, so there is no harm in eating less. 3, avoid partial food Fracture patients, often accompanied by local edema, congestion, bleeding, muscle tissue damage, the body itself has the ability to resist repair, and the body repair tissue, bone growth, bone scab formation, stasis and swelling of the raw material is to rely on a variety of nutrients, it is clear that the key to ensure the smooth healing of fractures is nutrition. 4. Avoid indigestible things Fracture patients are restricted in their activities because of the fixed cast or splint, coupled with the swelling and pain of the injury, mental anxiety, so appetite is often poor, and sometimes constipation. Therefore, food should be nutritious, but also easy to digest and laxative, avoid eating yams, taro, glutinous rice and other easily flatulent or indigestible food, it is appropriate to eat more fruits and vegetables.
