Is This Possible? and What Does It Entail?

Unless medically necessary, like it's causing you pain, I wouldn't even worry about it. They have to rebreak the bone, reset the bone, then you have to heal all over again. Rebreaking is SOOOOO PAINFUL.

When I was 6 I broke my arm in a WEIRD place. Because it was so swollen, I had to wear a sling for 2 days until the swelling went down so they could get clear X-rays because it was such a funky break. Because I was so young, it had already started to heal... REBREAK, OMG, I ALMOST PASSED OUT. I have forgotten the pain of childbirth, but I will NEVERRR forget that pain!

You should contact an orthopedic specialist for an evaluation. I'm sure it can be done but he/she can tell you if it should be done and the steps needed for treatment.

It would depend on the break and it's location. I've heard of doctors rebreaking the bone and then setting it.

Yes, it's possible. Please talk to a skilled/experienced/reputable doctor.

And home remedy for a broken bone? Really? I hope you don't mean herbs/acupuncture/poultice (fill in the blank).

It's possible, but as someone already said - painful! I would talk to an orthopedic specialist. Even if it's not bothering you (or whoever has the issue) I would still talk to a specialist. You never know what issues might show up later in life. My doctor (at OrthoTexas) handled a problem similar to this for my son and did great work.
