After a fracture, there are generally several stages a person will go through. These can typically be divided into the following stages: hematoma organization stage, fibrous connection stage, initial callus stage, mature callus stage, and then the remodeling stage. During these periods, the area of the bone is undergoing a metabolic process involving both osteoclasts and osteoblasts. During this metabolic process, calcium is required, and a deficiency in calcium can affect the healing of the fracture. Therefore, it is advised that patients with fractures should take calcium supplements. Along with calcium, it is also recommended to supplement with vitamin D, which can enhance bone absorption and calcium absorption, aiding in the healing of fractures. Thus, the conclusion is that fracture patients can indeed take calcium tablets.
