What is a fracture? | Cracks or breaks in bones due to physical stress |
Compound fracture | Open fracture |
Simple fracture | Closed fracture |
How are fracture repaired? | 1. Fracture hematoma formation 2. Callus formation 3. Spongy bone formation 4. Compact bone formation |
How does fracture hematoma formation happen? | -production of a large blood clot between bone fragments -fibroblasts, chondrablasts and osteoblasts establish a fibrous network -bone cells in the area die |
Callus formation | -cells of endosteum and periosteum ducks and migrate into fracture zone to create soft callus -callus stabilize the break and bridge bone fragments together |
Spongy bone formation | -osteoblasts replace Central cartilage of external callus with spongy bone and begin to form a bone (hard) callus |
Compact bone formation | -bone callus is remodeled and replaced with secondary bone -repaired bone may be slightly thicker and stronger than normal |
