Knuckle Cracking
I'm not a knuckle cracker myself. In fact, I hate it when people crack their knuckles. And I've frequently told people that cracking their knuckles would cause arthritis. After all, that's what everyone says. But according to this NY Times article (
republished in the Arizona Republic) it's not true. It's an urban legend.
Just reading this description of what causes knuckles to crack makes me cringe:
The loud pop of a cracked knuckle is caused by synovial fluid, the thick lubricant that surrounds every joint. When the fingers are stretched or bent backward, the bones of the joint pull apart. This creates bubbles of air in the fluid, which subsequently burst.
But as for the evidence that knuckle cracking doesn't cause arthritis, the article cites a 1990 study:
The largest study to explore a link to arthritis was published in 1990 in the Annals of the Rheumatic Diseases. It looked at 300 healthy people older than 45, 74 of them habitual knuckle crackers. The rates of arthritis of the hand were similar in both groups, though the knuckle crackers, on average, had reduced grip strength.
Still, I think I might keep telling people who are cracking their knuckles that it's going to give them arthritis, just to annoy them and maybe scare them into stopping.

mark,
Well try to improvise. push your back against back rest of your chair. but make sure your back rest is sturdy enough. and make sure your chair isn't the kind that moves.
I am fortunate enough to be double jointed and flexible. So I put my left arm behind my back, then I grab my right arm with my left hand. I then push forward my right arm and my left arm into my back. Boy does it feel gooooood!
you could probably do it without being double jointed but I wouldn't gurantee it.
Or maybe just have a co-worker pop it for you. Who cares if it's not professional. Just say your doc reccommends it.
Good luck.

Hello to all
I crack my finges but that isnt my worst habit, my worst is biting my nails. I've bitten them down so much it is hurting to type this.
I crack my knuckles because im a guitarist and a pianist and if i dont then i cant play properly. its something i have to do. i recently stopped cracking my toe though because ive done it so much that last week it dislocated and is now very painful. Doesnt put me off though.
Love to all
Beth

I can crack almost every single joint on my body. Actually, I can't think of one I cannot crack. I don't crack knees and shoulders, because these joints freak me out (I happen to know a little about anatomy), but I could if I wanted to. I can crack my sternum (I don't). I can crack my illium, and ichium (I do all the time), and tailbone, and little falangas at the tips of my fingers and toes, and the joints of my neck all the way up inside my skull. The rest of the spine is a joke. Elbows and arms are a joke. Knuckles? I don't even notice when I do it; at this point, there are specific anatomous circuits in my brain devoted to cracking behavior, like for breathing and hearbeat. I've been doing it for at least nine years. Maybe a couple years more. (No, my joints are not huge, just a little bigger and more transparent than normal.)
And let me tell you this guys: just like with alcohol and smoking, they will discover in time that this is an addictive and harmful behavior. It destabilizes your joints and makes a potential injury worse (doesn't mean you'll get an injury, but when you do, it will be very bad). Also, if you crack your neck (like I do quite often), it may cause problems with circulation and result in head aches (there were few people who had strokes as a result of an "adjustment" in chiropracter's office).
So, although it is not harmful in the short term, or if you do it only occasionally (like smoking and drinking), it is harmful if it becomes addictive. How do you know it's become addictive? If it hurts so much you cannot stop doing it. Your joints become less stables, so muscles around them tighten and spasm to keep them more stable. You feel discomfort, stretch the muscles and crack the joints, making them more unstable, making muscles spasm more, etc.
So, as for me, I am trying to stop and cut down on cracking joints. *Crack*... aaah... damn it...
Oh, by the way... chiropracters are such a bunch of phoneys. They are not even real doctors to begin with, so they are worse than psychiatrists. If you have back problems, seek out a real doctor, a neurologist or an orthoepedic (sp?).

i crack all my bones. its my biggest weakness. for the last past 8 yrs i have had my girlfriend step on my chest in honor to crack my sternum. stepping on my back is no big thing. i gotten to a point where i have her step on the side of my ribs. theres not a time im not cracking a bone. its bad from head to toe. it does get addiciting sometimes i dont know if i would rather have sex or have all my bones cracked.

Everyone describes joint cracking as a hobby.
I must crack my joints from exteme stiffnes, especially in my back. If I don't crack my back, I am in a great deal of discomfort. I must have someone step on my back, twist or bend over backwards over a ridge edge. The stiffness is not always easy to get rid of. It makes life very unpleasant at times.

I've been a knuckle/joint cracker for at least 15 years - I've noticed that sometimes the tension doesnt go away when I crack the joints. It makes me want to keep trying, that leads to soreness or injury to those joints... I can crack almost every joint in my body - even knees and shoulders, elbows, etc. I found this forum since Im trying to stop - good luck to everyone one else who wants to be freed from this addiction!! (at least we're not addicted to drugs!)

Another cracker here--as others have said, there's a dull ache from an uncracked joint and if it goes too long (it can be quite hard to get my right little toe to crack these days) it can actually get to hurting. It also makes them feel more flexible.
There's also the issue that a joint pushed almost to the point of cracking will likely hurt until it does crack.
All 15 finger/thumb joints, wrist (only if they have been inactive for at least an hour), elbow, knee, ankle, 9 joints of the toes (the little toe doesn't have the flexibility to crack the second joint), neck and low back.

I crack my knuckles, my toe knuckles and my back. I can't sleep at night because of the cracking and because i stress of having arthritis now i am so relieved. i'm still worried because im only eleven years old and it is os addictive.
Its so hard because there is no Nicabate CQ for knuckle cracking and you can't call a Quitline.
