<span>When a bone breaks your body immediately begins working to heal it. Within the first hours of a fracture a blood clot forms around the break and special cells call phagocytes begin cleaning germs from the bone fragments. Then, a soft callus composed of collagen is created around the break. Next, a hard callus forms as osteoblast cells work to create new bone to aid in the reconstruction process.
