Why articulations crack

And joint sounds can come and go, depending on how you position your body when you sit and sleep, and how you use your body when you move, Dr. Cracking, popping joints are so common that Dr. Stearns says his patients ask him about them just about every day. There are a few reasons why your joints snap and crack. This sound usually indicates that a muscle is tight, and is rubbing and causing friction around the bone, Dr.

The sound also could be coming from tendons rubbing over the bone. When you crack your knuckles, the sound is coming from the compression of nitrogen bubbles that naturally occur in the spaces of the joints, Dr.

The cracking is the sound of gas being released from the joint, an action called cavitation, Dr. The sound is not a cause for concern. Sometimes when the joint moves, gas is released, and you hear the "popping' or "cracking' noise. If you notice an increase in joint cracking, it is helpful to examine if anything has recently changed that is causing joint cracking. Have you had a recent injury? Broken bones, sprains, and tendon injuries can all contribute.

Even an old injury may sneak up to give symptoms. If so, then it is important to see an orthopedic specialist who can examine the condition and prescribe an appropriate treatment plan. Occasionally joint cracking can be caused by a more chronic condition, such as arthritis. It is common for this to occur in the knee joint. You might hear the joints cracking as the cartilage wears down and bone grinds against bone.

When it comes to "popping" or "snapping", another commonly affected part of the body is the shoulder. Shoulder joints have an incredible range of motion, so can be the noisiest joints in the body. If accompanied by pain or reduced movement, it is important to be evaluated by an orthopedic specialist to rule out injury.

Athletes can hear joint cracking when they participate in strenuous activities such as running and plyometrics—the sound results from tight muscles that are causing friction against bones. If athletes stretch appropriately before exercise, it can help to relax the muscles. In doing so, you can decrease the number cracking sounds, as well as decrease the risk of injury.
