Fractures

• Occurs when bone is subjected to forces, which
  are strong enough to disrupt its structural
  integrity.

5
COMMON CAUSE OF FRACTURE

• Accident/injury Motor vehicle accidents (MVA)
  and falls are the leading cause of fracture. 
• Aging- Bones weaken as we age.. 
• Disease and pathologic fractures- Diseases weaken
  bone by eroding the bone structure away until the
  weakened bone snaps.
• Bone fatigue- A condition that may occur even in
  healthy bones that are subjected to prolonged,
  excess stress. 

6
Closed or Simple Fracture

• A fracture that completely severs the bone, but
  does not break the skin.

7
Open or Compound Fractures

• The broken bone breaks through the surrounding
  tissue and the skin

8
Comminuted Fracture

• A fracture that shatters the affected bone into
  many fragments.

Greenstick Fracture

• A partial fracture in which one side of the bone
  is broken while the other side is bent.

12
Compression Fracture

• Usually occur in the vertebrae and are a result
  of extreme stress which pushes the vertebrae
  together.

13
Stress Fracture

• Microscopic fractures in a bone resulting from
  repeated stresses.

14
Colles Fracture

• A break in the distal portion of the radius
  usually caused by falling with your arm
  outstretched.

15
Epiphyseal Fracture

• A fracture between the epiphysis and the
  epiphyseal plate of a growing bone.

16
Impacted

• The broken ends of the bones are driven into
  another bone
