The system that comprises all of the bones in the human body is the skeletal system.

It provides the following:◦ Support

◦ Protection

◦ Produces blood cells

◦ Stores minerals

Depending upon the type of accident and its impact; bones can be fractured in many different ways.

Sometimes we can have accidents, like falling, which causes our bones to break.

There are several types of bone fractures.

SIMPLE

COMPOUND

SPIRAL

OBLIQUE

IMPACTED

TRANSVERSE

GREENSTICK

COMMINUTED

Simple fractures have no open skin wound.

Many simple fractures can be stabilized and heal properly when splints or casts are applied.

Compound fractures have an open skin wound, as shown here.

They are more serious than simple fractures & take longer to heal.

Some compound fractures never completely heal.

To the right are multiple comminuted fractures.

These are fractures in which the bone is shattered, splintered, or crushed into small pieces or fragments.

Healing these kinds of fractures often require surgical insertion of metallic pins, nails, plates, wires, or screws to hold the fragments in place to heal with minimal deformity.

Other kinds of fractures:◦ Compression

◦ Pathologic

◦ Stress

◦ Colles (wrist fracture)

Fractures occur most often in children.

The average person sustains at least two fractures in their lifetime.

I have never fractured a bone.
