It is called a dislocation. A doctor can put it right again, but note I said a doctor - not somebody nearby who says, "Oh, I know how to do that!" (which happens on sports fields not infrequently).
When a bone is forced out of its joint, it is called a dislocation. This causes severe pain, swelling, and loss of joint function. It is important to seek medical attention promptly to properly realign the joint and prevent further injury.
The generic term for a bone that is displaced at the joint is "luxated". A partially dislocated joint may be called subluxated.

It is very likely but if you have broken it in a certain position then it might not swell. If it is painful but not much swelling you may have fractured the bone or the bone may have partially been forced out of the joint.
