Bone fractures

Types of Bone Fracture

• There are seven types of fracture1.Greenstick2.Simple3.Compound4.Spiral5.Comminuted6.Impacted7.depressed

Greenstick Fractures

• Also called an incomplete fracture

• Break does not extend all the way through the bone

• Common in children. Their bones are more flexible

Simple Fracture

• No tear in the skin

• Break extends all the way through the bone

Compound Fracture

• Broken end of the bone tears skin from the inside

• Bone may break into several fragments

Comminuted Fractures

• Bone has broken into several pieces

• Common in the elderly with brittle bones

Spiral Fracture

• A ragged break that occurs when excessive twisting forces are applied to the bone

• Common sports fracture

• Common child-abuse fracture

Impacted Fractures

• Ends of the bones are forced into each other

• Most common cause: Falling with out streched arms

Depressed Fracture

• Bone is broken and forced inward

• Most common in skull fractures
