Cracking Down on Knuckles

Cracking Down on Knuckles - Reviewed by Kidzworld on Dec 27, 2006

Could your mom be yanking your chain when she tells you cracking your knuckles will cause arthritis? Find out what that popping noise is and the dangers of cracking your knuckles.

You've all heard the story that cracking your knuckles will cause arthritis. Maybe your mom can't stand that "popping" noise and that's why she tells you knuckle cracking will damage your finger joints. Kidzworld did some digging around to find out what makes that "popping" noise and if it causes arthritis. Here's what we found out.

The Real Deal on Cracking Your Kuckles

What's really happening when you "crack" your knuckles is that you are either pushing the joint back into or out of its normal position. Joints are the meeting points of two separate bones which are held together by connecting tissues and ligaments. A thick, clear lubricant (made mostly of carbon dioxide and some nitrogen) called synovial fluid is found between the bones. When you stretch or pull your finger to get that desired popping noise, you are causing the bones to pull apart. Pressure is reduced on the synovial fluid and bubbles form that quickly expand and then burst - which is why you get that noise.

Does Knuckle Cracking Lead to Arthritis?

Not everybody's joints crack. Some people have a larger separation between the bones and some people can't relax enough to allow the bones to separate. If you can crack and your mom tells you, you're going to get arthritis, she's just yanking your chain. There is no scientific evidence that cracking your knuckles leads to arthritis. However, it can't be good to repeatedly push a joint beyond its normal physical range. Besides that, it's annoying. Cracking your knuckles can cause a decrease in your grip but unless you're signing any multi-million dollar contracts as a pitcher, it's not worth giving up. But it's still annoying.

1 I actually crack my fingers ALL THE TIME. That is the only way I can relieve the tension that hurts my fingers. My dad actually doesn't like me doing it, and my mom is the squeamish one. When someone cracks their knuckles, I feel like I have to crack mine. I can't remember when I started... probably a few years ago.

1 No the cracking sound does not make me squeamish, it relieves the tension in my fingers after writing for a while.

1 I've cracked my knuckles, my toes, my back, my neck, for, like, ever! It feels great and relieves stress (I hope and think!!) I do it all the time, now everyone at my school's doing it!

1 I don't get squeamish when people pop their knuckles or any other joints. I pop my neck, back, knuckles, wrist, elbows, knees, ankles, toes... Haha, you name it, I pop it! =P

1 I pop my knuckles all the time - it's a habit I can't stop. I pop my toes, thumbs, neck and back... pretty much anything that can be popped I pop! It feels good and I like doing it.

1 I crack my knuckles sometimes but the main joint I pop is my elbows. It feels so good but I am worried it's bad for the bone or something.

Do you crack your knuckles? Is it a habit you can't stop? if the sound of "popping" knuckles makes you squirm.

Bag or Slag That Popping Noise?

  • I gotta join in when someone cracks a knuckle.
  • I glare at any cracker rude enough to do that in public.
  • I cringe at that horrid sound.
  • I pull my hair out and run, screaming in terror.

Dear Dish-It In The Forums

Hello! I'm in need of urgent advice. The guy I have a crush on and I were best friends around two years ago. Somebody told him that I like him, and now he avoids me like the plague... I really just want to be friends with him again even if he doesn't like me back. What should I do? I'm quite an awkward girl, and I can't make conversation for the life of me. We're going into seventh grade, and I haven't talked to him nor seen him all summer. Please help!

I totally feel the same way. The one guy I thought was interested friend-zoned me, so I've been kind of closed to relationships. One thing I've learned is not to jump into a relationship just because everyone else is. Just think, in 20 years they'll have all these bad memories of their many relationships, and you'll learn from their mistakes. Wanting to be in a relationship doesn't make you desperate either. You just feel a little left out. Trust me, I've been there. Don't feel alone. Being single, well, sucks, but don't worry, we've got your back, and I just know there's someone out there waiting to meet you.
