What Causes The Noise When A Joint Breaks

What Causes The Noise When A Joint Breaks

Experts have several theories as to what causes the noise when joints crack or burst. Joints can produce different sounds - popping, tearing, and creaking. The joints that crack are knees, ankles, back, and neck.

Your joint is the connection point between two bones, where the bones can move relative to each other. The type of joint that you can easily "burst" or "split" is the hand joint. There is a film around the joints that contains fluid that helps the joints move smoothly.

When this happens, the connection is cut, releasing gas and bubbles from it. Sometimes, when the joint moves, it releases gas and hears a "pop" or "crack" sound. You don't need to worry unless you experience pain or swelling in your joints. A painless noise in the joints or ligaments is common and normal.

When the bones of a joint separate, negative pressure means that gas (possibly nitrogen) builds up in the synovial fluid, resulting in sudden blistering - the scientific term is Tribonucleation.

The joint cannot be broken again until the gases dissolve in the synovial fluid, which explains why it is not possible to break the same joint again.
