Crepitation also known as crepitus is the sound heard when the ends of a broken bone move together.

If you truly have a fracture, the bone is broken. Rubbing it can cause the ends of the broken bone to damage tissue near it. That is why fractures are kept from moving by a cast or splint.

Fibrous and fatty tissue
it is a fracture in which the two ends of the broken bone are separated from one another
A compound fracture is called this. If the bone sticks out of the skin it is called a compound open fracture.

With regards to movement and support to the body, a broken bone will reduce the ability of the bone to support the weight of the body. A bone acts as a frame for the muscle to pull against and thus enable movement. The muscle is unable to pull against a broken bone and therefore movement is reduced or not possible at all.
If somebody continues to try to walk, having broken an ankle, the result will be further injury to the muscles, bone ends, blood vessels, cartilage, and skin surrounding the fractured bone. Not a pretty thought. That's one reason why we IMMOBILIZE the injured area in fractures.
Long bones have spongy bone at the ends, more properly known as cancellous or trabecular bone.
