After a fracture, it is essential to take proper calcium supplements in the diet because the deposition of calcium salts during the healing process of the fracture is very helpful for bone healing. In addition to calcium supplementation also sun exposure, otherwise the calcium is not absorbed and it is useless to eat how much is finally excreted from inside the feces. In the process of calcium supplementation, 1-25 hydroxyvitamin D3, or ossification triol, is a very important component that can take the calcium we eat into the intestine, absorb it into the bloodstream, and finally complete the deposition in the bones. Bone soup inside the composition is very complex, the main component of the bone is hydroxyapatite, which is very hard, boiling water is not boiled calcium, so the content of calcium in bone soup is very, very low. Therefore, if you want to drink bone broth to replenish calcium is not enough, it is better to eat some shrimp skin, or buy some calcium tablets in the pharmacy is more helpful. So active vitamin D is very important for calcium supplementation, how is it produced? There is a kind of cholesterol in the skin, which turns into vitamin D3 in the body under the sunlight, and then the conversion is done in our liver and kidneys before it finally becomes active vitamin D, which acts in the intestine. Therefore, it is important to take the patient outside in the sun after the fracture to promote the production of vitamin D in order to promote the absorption of calcium. One of the most important objectives of surgical treatment is to enable the patient to move early. For example, if a patient has a lower extremity fracture, getting out of bed and going to the bathroom is a process that will not affect the healing process. The healing process of a fracture is very complex and is clinically divided into four phases: 1. early after the fracture, a local hematoma forms, just like a blood tofu, a pool of blood around the fracture, which we call the hematoma phase; 2. 3-7 days later, due to the activation of the internal and external coagulation system, the hematoma at the fracture end coagulates into a blood clot and the hematoma mechanizes to form granulation tissue, which becomes the hematoma mechanization phase; 3. When the hematoma is replaced by cells in the body, it is called the period of bone scab formation; 4. Finally, the original bone scab is replaced by lamellar bone to form a strong bony connection at the fracture site, which is called the period of plasticity. And there is no mention of water in this process. In addition, there are two types of cells inside this process – osteoblasts, osteoclasts – that play a very important role in the fracture healing process. Osteoblasts produce a large number of osteoclasts like a house builder, secrete and synthesize some collagen, matrix, fibers, and absorb calcium and phosphorus into the pores of the fibers for precipitation and crystallization, and finally calcium salts settle on top, and like building a house, the building is stacked layer by layer to form new bone. Osteoclasts eat the old, bad bones and let the new bones grow again. And this process also has nothing to do with water. However, water is also important because it is an important substance in the metabolic process. Normal water consumption is usually enough, and you should drink at least 2,000 ml per day.
