There are several ways to promote rapid healing of fractures: first, strengthen nutrition, eat more food rich in protein, vitamins and calcium, such as bone soup, tofu soup, and seafood with high calcium content, etc., which can promote rapid healing of fractures. Second, firmly fixation, using small splints, plaster, braces, plates, screws, intramedullary pins, etc. to effectively fix the fracture site, so that the newly grown bone scabs will not be broken, so that the fracture can be quickly healed. Third, strengthen functional exercise to promote local blood circulation, under effective fixation, encourage the patient to carry out functional exercise of the affected limb as soon as possible. The muscle contraction can stimulate the fracture end to produce new bone scab, which can make the fracture end squeeze tighter and make the osteoblast osteogenesis more active, so that the fracture can heal quickly.
