3) after the break in the bone occurs, blood vessels in that area are damaged and blood surrounds the fracture. The blood solidifies to form a clot, which reduces bleeding. White blood cells migrate into the area to remove bacteria and damaged cells. Osteoclasts migrate in to remove dead bone matrix. Secondly, fibroblasts migrate into the fracture to form a plate of cartilage to prevent further movement and damage at the fracture site. Thirdly, osteoblasts invade to replace the cartilage with bone matrix in the form of spongy bone. Lastly, the bone matrix will be remodeled as compact bone replaces spongy bone.
