1. Bone Fractures

2. Bone fractures Question: What is the difference between a bone fracture and a bone break?

3. Bone fractures Answer: There is no difference. They are 2 terms describing the same thing--- The bone is broke

4. Bone Fractures Types: 1. Simple 2. Compound 3. Complete 4. Incomplete

5. Bone Fractures Complete Fracture- The bone breaks into two or more parts

6. Bone Fractures Incomplete Fracture- bone cracks but does not break all the way through.

7. Bone Fractures Compound Fracture also called an open fracture the bone breaks through the skin it may then recede back into the wound and not be visible through the skin

8. Bone Fractures Simple Fracture- also called a closed fracture the bone breaks but there is no open wound in the skin.

9. Bone Fractures Simple Fracture- Greenstick : an incomplete fracture in which the bone is bent. This type occurs most often in children.

10. Bone Fractures Simple Fracture- Impacted fracture is one whose ends are driven into each other. commonly seen in arm fractures in children A.k.a. buckle fracture

11. Bone Fractures Treatment: Reduction: realignment of the broken bone ends

12. Bone Fractures Reduction Closed Reduction- Bones are coaxed back into their normal position by the physician’s hands

13. Bone Fractures Reduction- Open Reduction: surgery is performed and bone ends are secured together with pins or screws

14. Bone Fractures Immobilization- After bone is reduced Cast or traction allows the healing process to begin

15. Bone Fractures Healing Process: 6-8 weeks for a simple fracture much longer for large bones much longer for bones of elderly people (poor circulation)

16. Bone Fractures 4 major events in bone repair

17. Bone Fractures Bone Repair step one: Hematoma is formed— a blood filled swelling caused from blood vessels rupturing when bone breaks

18. Bone Fractures Bone Repair step two: Fibrocartilage callus forms— Cartilage, bone and collagen fibers laid down Acts as a splint Closes the gap

19. Bone Fractures Bone Repair step three: Bony Callus formation— Osteoblasts and osteoclasts come to the area Fibrocartilage is replaced by spongy bone

20. Bone Fractures Bone Repair step four: Bone Remodeling— In response to mechanical stress Strong permanent bone formed at site of injury
