- 1. Hematoma Formation
- 2b. Fibrocartilage Callus
Formation
- 3. Bony Callus of Trabecular Bone
- 4. Healed
- 5. Much later remodeling
occurs to polish up
- Excess diaphysial tissue removed
- Excess material within medullary cavity also removed
- Callus= Hardened Bone
- 2a. New Blood Vessels
- Phagocytes invade
- Phagocytes clear away the debris
- Fibroblasts invade
- Produce collagen
- Precursor osteogenic cells invade
- Chondroblasts
- lay down
cartilage
framework
- Osteoblasts
- Start forming
Spongy Bone
- Usually within one week of fracture
- Bone breaks so the
periosteum blood
vessels break
- Need to form hematoma
- WOUND HEALING
- Very
Similar to
