question about being double jointed?

Question

i'm double jointed in my fingers but not as bad as my brother i had a couple of questions about it:

1. is it considered a birth defect? if so wat happens and why?

2. does it effect the way u do things with ur hands? because my brother has some difficulties cutting with a knife (he's 11 years old) i always have to help him with that cause he can't hold the knife right.

3.is cracking ur nuckles while double jointed more dangerous then cracking ur nuckles without being double jointed

Answer 1

1) Sometimes
2) Yes
3) No

If you or your brother bruise easily, or other family members bruise easily, you should discuss your "double-jointedness" with your doctor, and if he or she is unaware of associated risks, you should ask to be referred to a specialist in clinical genetics.

I'm sorry, I don't like to leave with a worried outlook, but sometimes it is important to urge people to seek medical advice. Beyond that, it is not possible to make a diagnosis without an exam.

Answer 2

There is no such thing as people actually have two joints in a place where most people only have one. When a person is able to bend his/her thumb back really far or flex their finger joints into odd positions, it's not because they actually have "double joints". It's because their joints are exceptionally flexible. Please click the link for more info. It will probably answer alot of your questions.
