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

|
A fracture that results in microscopic fissures in the bone without evidence of injury to other tissues is called?
|
A stress fracture
|
|
What causes stress fractures? What other statistics should be known about stress fractures?
|
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.
