Bone Injury

Bones are  strong enough to support your growing body, but too much pressure in one area can cause a bone to break. A broken bone can be caused by a hard fall off your bike or a bad collision on the soccer field. Although a bone fracture is very painful, the body is prepared to fix the break!

How can my body fix a break?

When a bone is broken, so are the blood vessels inside. These bleed, making a clot around the break. Special cells in the clot clean the break to prevent infection. Young cells from the bone marrow form cartilage, the same material that makes up bendable parts of the body such as the nose and ears. Another kind of cell then moves into the break to eat up the cartilage, while still another kind of cell forms new bone.

Healing a broken bone is very similar to growing bone in the first place! The body is prepared to continually renew the bone with the process of bone renovation so it produces an entire crew of cells to repair old bone tissue that can also fix broken bone tissue.

This makes bone tissue unique because the new bone is just as strong as the bone was before it broke! Other tissues in the body, such as skin and heart muscle, can't heal as well and form scars in the places where they were mended.


Remember!

Although bones are sturdy enough to support most activities, they can break.
