Osteogenisis vs Ossification?
Osteogenisis: Process of bone formation
Ossification: Process of formation of the bone matrix and deposition of minerals
Stages of Bone Healing
1: Hematoma formation
2: Fibrocartilaginous callus formation
3: Bony callus formation
4: Remodeling
When does stage 1 of bone healing take place?
1- 2 days after fracture
What happens in stage 2 bone healing?
Fibroblasts and osteoblasts migrate to fracture site
What happens in stage 3 of bone healing?
Ossificaiton begins in 3rd or 4th week
What happens in stage 4 of bone healing?
Osteoclasts remove necrotic bone
