Other than my bones I've found my body has some weird almost supernatural healing power. My favorite example is that when I was a kid and needed braces, I went to like five different orthodontists who told me I'd need head gear to correct my bite. There's no way I was gonna do that, so I found one that told me that they would try with just rubber bands but might have to resort to head gear if they didn't work. So, of course, I never once wore the rubber bands. Every checkup they told me I was doing a fantastic job with my rubber bands and I got my braces off with a perfect bite without ever wearing rubber bands or wearing head gear.
I can move my left arm and both legs out of their ball-and-socket joints at will, but not all at the same time. I remember one time (I think it was the day I got baptized or something) I was at some people's house where they had this enormous pool and entertainment area up on their deck and I was eating a hot dog with a boy from my church. They were talking about someone dislocating their shoulder and needing medical attention so I just pulled my arm out of its socket and told him to feel my shoulder. His fingers went down into my skin, behind my humerus, and into the hollow joint. He completely freaked out.
My legs are a different story though and the only way I know how to remove my femur from my pelvis is by pushing my hip outward, almost like what these women are doing here:

I can go farther than that until the rounded top of my femur is visible in my side like a small concealed tumor. I use the other leg for balance though, so pulling that femur out would not only be a bad idea and a risk of injury, but I also can't push the other hip outward to get it out in the first place.
