A cracked bone is clinically called a fracture of the bone and is a mild type of fracture, so its treatment is usually conservative, including fixation of the affected limb in a cast or brace for about 6-8 weeks. During immobilization, care should be taken to elevate the affected limb above the heart, which helps to reduce local pain. It also helps to reduce the swelling by facilitating the venous return. In addition, you can also apply some traditional Chinese medicine with blood circulation and blood stasis effect, such as safflower oil or orthopedic water, which can promote local blood circulation and facilitate the repair of the fracture. These medications can significantly reduce local pain, and also intravenous medications to promote fracture healing, such as bone peptide injection.
