How does a bone heal?
The immediate response to a fracture is bleeding from the blood vessels dotted throughout our bones.New bone starts to form mostly at the edges of the fracture.To fill the void space between the broken ends, cells produce soft cartilage. Then, special cells called osteoblasts create a hard bony callus using collagen and minerals like calcium and phosphorus. Thus forming our new bone. However, this new bone is irregular in shape. Hence, cells called osteoclasts start remodeling the bone. Resulting in the formation of bone similar to the original shape.Cartilage, or soft callus, formation peaks around 8 days after injury.
