pic: What are these parts?

[AdamHeard]

No, I tore the cartilage near the sternum pretty bad.

There is a condition known as "pectus excavatum" which is that "hole" in the chest you see on some people, I apparently had a very, very slight case in which you cuoldn't even tell really. When I get kneed perfectly lined up there, it pushed in rather far and became a rather severe case... It was even cutting off one of my bronchial tubes almost completely (It also was pushing on my heart and supposedly raising my blood pressure). the bar had to be put in to flatten it out while it regrew (which apparently takes a long, long time...).
