Ⅱ.简答题
Have you ever suffered a broken bone? The medical term for a broken bone is a fracture.But there are different kinds of fractures.A single fracture is when a bone is broken in just one place.You may have heard the term hairline fracture.This is a single fracture that is very small,like the width of a hair.A complete fracture is when the bone comes apart.
When a bone is broken in more than two places or gets crushed,the name for it is a comminuted fracture.
Still another kind is a bowing fracture.This happens with a bone that bends but does not break.It happens mostly in children.
Have you ever heard of a greenstick fracture? This is when a bone is bent and breaks along only one side,like a young stick of wood.
Another kind of break is an open or compound fracture.This is when the bone breaks the skin.This is very serious.There is both bone damage and a risk of infection in the open wound.
A lot of things happen as the body reacts to an injury
like a
broken
bone.You
might
suddenly
feel lightheaded.You might also feel sick to your stomach.
People who are seriously injured can go into shock.They might feel cold and unable to think clearly.Shock requires immediate medical attention.
But while broken bones can be painful,they are generally not life-threatening.Treatment depends on the kind of fracture.A doctor takes X-rays to see the break and sets a broken bone to make sure it is in the correct position.
