Why do our joins click sometimes? is it the bone clicking?

Answer 1

I think you are talking about a "joint". That is the cartilage popping.

Answer 2

The clicking noise is caused when a burst of air enters your joints. When you pop your nuckles, air enters the joint and causes a popping sound. When you walk, your joints might pop themselves to destress. It is the same feeling your back gets after a good pop from a Chiropractor, the joints are destressing.

Joints are supported by a complex arrangement of muscles and tendons. These keep the joint stable, allowing it to function properly. Some people have slightly lax joints and when this is the case the joint may click. Minor trauma such as a sprain may cause the joint to start clicking because inflammation and damage disrupts the stability and organisation of the supporting muscles and tendons. Once this has healed the clicking disappears. In fact, more often than not the person won't even be aware that the injury has happened.

Provided that when the joint clicks it isn't associated with pain, swelling, redness or a reduction in the joint's movements, then it's probably all right to ignore it. If any of these symptoms are present then the doctor should be consulted.

Answer 3

When your joints crack or "Click" such as when you pop your knuckles, you are actually creating a vacuum in the joint's bursa. The bursa is a fluid filled sac that contains synovial fluid which helps lubricate your joints so you won't be in pain everytime you make a certain movement! When you crack your knuckle, the part of the membrane becomes closed off and all of the synovial fluid rushes to the other side. When your joint is released back to it's normal position, the fluid comes rushing back into the reopened part of the membrane and crashes against one of the walls, creating a "popping/cracking" sound. Neat, huh? Also, did you know that whenever you pop a knuckle or your joint clicks, the atmospheric pressure within your joint becomes equal to the pressure outside, which results in a "boiling" effect of your synovial fluid! In turn, it evaporates, but don't worry your synovial membrane is always there to secrete more!

Answer 4

It's not the bone itself that clicks, it's a bubble of gas, more likely to be nitrogen, being forced from one side of the joint to the other under pressure.
Your joints are surrounded by a fluid filled sack called the synovium. This sack contains synovial fluid and it's this fluid that lubricates the joint cartilage so it is slippy to aid movement. Cartilage is like what the non stick surface is to a frying pan.

Answer 5

What happens is sometimes when we move in certain ways air will get into the joint and cause sort of a little suction bubble. Then if we move again in a certain way to release that pressure bubble, our bone will get sucked back into the joint socket creating a "click" or "crack" sound of the bone. This is why people can crack their fingers a lot, because we are always moving our fingers, they are very suseptable to air getting into the sockets of the joints.

Answer 6

It is the sound from the different parts inside rubbing against one another-it is from a loss of fluid on a joint.

Answer 7

No, it's the cartilage shifting, It's nothing to worry about as many people have that problem.

Answer 8

Its an age thing.......... wear and tear.
