4 steps to fracture healing
Bony Callus Formation (2)
osteoblast and osteoclast migrate into th area and multiply. Fibrocartilage is replaced by callus made of spongy bone, the bony callus
Bone remodeling (1)
the bony callus is remodeled in response to the mechanical stressed placed on it, it forms a strong permanent patch at the fracture site.
Fibrocartilage Callus Formation (4)
the break is splinted by fibrocartilage callus.Growth of new capillaries and disposal of dead tissues by phagocytes.Connective tissues for a repair tissue to splint the bone.
hematoma formation (3)
blood vessles are ruptured when the bone breaks. blood-filled swelling forms. bone cells deprived of nutrients die.
