Bone heals by making cartilage to temporarily plug the hole created by the break. This is then replaced by new bone.
A fall, followed by a crack - many people are no stranger to this. Broken bones are painful, but the majority heal very well. The secret lies in stem cells and bone's natural ability to renew itself.
Many people think of bones as being solid, rigid, and structural. Bone is, of course, key to keeping our bodies upright, but it is also a highly dynamic and active organ.
