4 steps to repair a bone fracture?

Answer 1

1, Blood escapes from ruptured blood vessels and forms a hematoma.

2, Spongy bone forms in regions close to developing blood vessels, and fibrocartilage forms in more distant regions.

3, A bony callus replaces the fibrocartilage.

4, Osteoclasts remove excess bony tissue, restoring bone structure much like the original.

Answer 2

1. Hematoma formation- blood vessels, tissues in broken bone are torn resulting in a Hematoma mass of clotted cells. Bone cells with no nutrition will die and area will become irritated.

2. Fibrocartilaginous callus formation- phagocytic cells invade the area and begin cleaning up the debris.

3. Bone callus formation- about 1 week into repair, new bone begins to repair. This is called a bony callus. This continues for about 3 months.

4. Bone remodeling- excess material removed, shaft was reconstructed.

Answer 3

1. First Aide measures - control of bleeding with open fracture; splinting of area

2. Assessment - skin color; type of fracture; etc.

3. X-Ray prior to reduction. A fracture may need surgical reduction. Reduction means re-aligning the bone into its proper position.

4. After re-setting the bone, casting is done.

5. Casting is a muti-step process that protects the skin; application of the cast; allowing the cast to "set".

6. Often a re-X-Ray to check alignment.

7. Re-assessment in the hospital or at home for 24-48 hours for swelling of fingers or toes, skin temperature, pain, etc. The cast may need removed, and the area re-casted.

8. Casts generally stay on anywhere from 2 to 6 weeks at which time a physician re-evaluates. Another cast may be needed.

Bones heal almost like building a bridge. The body begins filling in the "space" between the broken ends, which is why it is important to have the broken ends as close as possible and in proper alignment. The body continues to "fill in" new bone cells but the bone needs time to harden and become stronger at the point of the break. Healing of bone continues even after the cast is removed.

Kids

Sometimes your bone breaks when you fall over.To treat it, you go to hospital.

1. The doctors will X-ray the bone and work out what type of broken bone it is.

2. The doctors move the bone into the right place.

3. The doctors put a plaster cast on to keep it in place.
