Fractures:
A fracture where both ends retain their normal alignment is called a ______________________ fracture.
A fracture where both ends do not retain their normal alignment is called a ______________________ fracture.
A fracture where the bone is broken all the way through is called a ______________________ fracture.
A fracture where the bone is not broken all the way through is called a ______________________ fracture.
A fracture where the break is parallel to the long axis of the bones is called a ______________________ fracture.
A fracture where the break is perpendiciular to the long axis of the bones is called a ______________________ fracture.
A fracture where the bone end breaks through the skin is called a ______________________ fracture.
A fracture where the bone ends do not break the skin is called a ______________________ fracture.
A fracture where the break is parallel to the long axis of the bones is called a ______________________ fracture.
