1. Fractures:

2. What is a Fracture? A fracture is the medical term for a broken bone.
Fractures are common; the average person has two during a lifetime.
Fractures occur when the physical force exerted on the bone is stronger than the bone itself.

3. Types of bone fractures
All are classified within the following 4:
open
closed
complete
incomplete
There are further classifications after that

4. Open Fracture:
An open fracture is a fracture where the broken bone is exposed.
That is dangerous because of increased chances of infection.
It is also called compound fracture.

5. Closed Fracture: Also known as simple fracture
A closed fracture is a fracture where the bone is broken, but the skin is intact.

6. Complete Fracture:
The two pieces of the bone, resulting from the fracture, completely separate from each other.

7. Incomplete Fracture:
In an incomplete fracture, the two pieces of bone, resulting from the fracture do not completely separate from each other; the bone pieces are still joined to some extent.
This happens when the crack (or fracture) does not break completely through the entire width of the bone.

8. Comminuted Fracture:
In this the bone splits into multiple pieces.

9. Avulsion Fracture:
An avulsion fracture is a closed fracture where a piece of bone is broken off by a sudden, forceful contraction of a muscle.
This type of fracture is common in athletes and can occur when muscles are not properly stretched before activity.

10. Stress Fracture: It is a common overuse injury.
It is most often seen in athletes who run and jump on hard surfaces such as runners, ballet dancers and basketball players.

11. Linear Fracture:
In this the fracture is parallel to the bone's long axis.

12. Transverse Fracture:
In this the fracture is at a right angle to the bone's long axis.

13. Oblique Fracture:
In this the fracture is diagonal to a bone's long axis.

14. Spiral Fracture:
In this at least one part of the bone has been twisted.

15. Greenstick Fracture:
Greenstick fractures are childhood injuries wherein the bone breaks on one side but remains attached on the other. This type of fracture is so named because the break is similar to what happens if you try to break a fresh twig.
