Front 1

If the bone ends are out of normal alignment in a fracture, what is that called? If the bone ends retain their normal position, what is that called?

Back 1

A displaced fracture vs. a nondisplaced fracture

Front 2

What two terms apply to a fracture with broken ends that break through the skin? If the ends do not break through, what terms are used?

Back 2

A compound or open fracture vs. a simple or closed fracture

Front 3

A fracture with splinters and small bone fragments that lie between the two main fragments is called?

Back 3

A comminuted fracture

Front 4

A fracture where one side of the bone is broken, and the other side bent is called? (Often found in children)

Back 4

A greenstick fracture

Front 5

A fracture in which one end is forcefully driven into the interior of the other is called?

Back 5

An impacted fracture

Front 6

A fracture that results in microscopic fissures in the bone without evidence of injury to other tissues is called?

Back 6

A stress fracture

Front 7

What causes stress fractures? What other statistics should be known about stress fractures?

Back 7

They are caused by repeated strenuous activity such as running or jumping; can also be caused by diseases that disrupt normal bone calcification such as osteoporosis. 25% of stress fractures involve the tibia. Stress fractures do not tend to show up clearly on an xray, but can show up on a bone scan.

Front 8

A fracture in which the distal end si the radius and the distal fragment is displaced posteriorly is known as?

Back 8

A Colle's fracture

Front 9

A fracture which involves the distal end of the tibia and results in serious injury to distal tibial articulation is know as?

Back 9

A Pott's fracture

Front 10

If a break occurs parallel to the long axis of the bone, it is referred to as? If it instead breaks perpendicular to the long axis?

Back 10

A linear fracture vs. a transverse fracture.

Front 11

List the 5 tissue densities in decreasing radiopacity.

Back 11

metal
bone
soft tissue (water)
fat
air

Front 12

A fracture in which bone is crushed is?

Back 12

A compression fracture

Front 13

A fracture that results in a ragged break from excessive twisting forces applied to a bone?

Back 13

A spiral fracture

Front 14

A fracture in which a portion of bone is pressed inward?

Back 14

A depressed fracture

Front 15

A fracture in which the the epiphysis separates from the diaphysis

Back 15

An Epiphyseal fracture
