Primary Brain Injury Open Head Injury
Four types of fractures associated with open head injuries.
linear fracture - A linear fracture is a simple, clean break in which the impacted area of bone bends inward, whereas the area around it bends outward. Linear fractures account for about 80% of head fractures.
depressed fracture - In a depressed fracture the bone is pressed inward into the brain tissue to at least the thickness of the skull.
open fracture - In an open fracture, the scalp is lacerated, creating a direct opening to the brain tissue.
comminuted fracture - involves fragmentation of the bone, with depression of the bone into the brain tissue.
