1. Bone Fractures

2. Simple fracture – bone does not break the skin (closed)
Compound fracture – bone breaks through skin (open)

3. Comminuted – many fragments

4. Compression – crushed, (typical in vertebrae)

5. Depressed – pressed inwards (typical in skull)

6. Impacted – ends forced into each other (ex. break a fall)

7. Spiral – ragged, slanted break from twisting (sports, child abuse)

8. Greenstick – incomplete (more common in children)

9. Treatment & Healing
Reduction – realignment of bone

10. Hematoma forms
Fibrocartilage callus forms – a mass of repair tissue, acts to close gaps

11. Bony callus forms – osteoblasts and osteoclasts migrate and work to replace fibrocartilage callus with spongy bone
Bone remodeling (osteoclasts and osteoblasts)
