1. Hematoma develops: Blood clot
2. Callus formation:internal calus unites the inner edges and external callus stabilizes the outer edge
3.Chondrocyte activities: external callus has been replaced by bone. Dead bone near the break is removed and replaced.
4. Osteoblast activity: Osteoclast and osteoblast remodel the region. little or no evidence once healed |

1.Catilage enlarges, chondrocytes enlarge and die. Leaving cavities in cartilage
2. Blood vessels grow on the edges of cartilage. cells convert to osteoblast. shaft becomes enshealthed in a superficial layer of bone.
3.Blood vessels invade the central region.Osteoclast begine producing spongey bone. Bone formation spreads on the shaft
4. Remodeling occurs.shaft becomes thicker. Cartiledge near epiphysis is replaced by bone
5.cappilaries and osteoblast migrate into the epiphysis create secondary ossification centers
6. Epiphysis filled with spongey bone. Articular cartiledge remain. Metaphysis and epiphysis from the diaphysis. |
