Does knuckle cracking cause any harm? In fact, this is a very old question, because this is a very common habit among people Before answering this question we need to understand what kind of phenomenon is this and what causes that sound. Our joints are involved by ligaments that form a capsule and inside that capsule there is a liquid called synovial fluid which has the function of lubricating this joint, reducing the friction Now, a group of researchers in 2015, I’ll leave the reference of this article down here along with others, They used Magnetic Resonance to film what is happening inside the joint. the video shows the space between these two bones What occurs is that the internal liquid as the pressure decreases a gas bubble forms It is at the moment when the bubble forms that the popping noise occurs. Watch again: It was formerly believed that it was at a time when the bubble burst that the sound of the crack occurred But no,
the crack occurs at the moment of bubble formation Notice that some people are afraid of cracking their fingers. Some think it is bad because they think that one bone is hitting the other or that the crack occurs due to a tendon bursting But it’s nothing like that. It takes about 20 minutes for you can crack your joint again Because these gases released by the distraction of the joint are gradually being absorbed again. And when you return to the normal situation you will again be able to snap your fingers. Now, there is another research where through a synthetic joint was observed the same phenomenon. Now about the health of the joints, research shows that there is no correlation between the insidence of arthrosis in the elderly and the habit of snapping the fingers. What has been observed is that people who have the habit of cracking their fingers have greater flexibility of the ligaments Because it gets stretched, but this can rarely cause any problems So do not worry about this But there are other types of cracks that can do harm. There are people who every time they move their fists hear: “tec! Tec! Tec!” Or the shoulder… listen this sound This kind of crack occurs through another phenomenon It can actually occur due to a bone friction or a tendon scraping into some bone acting as an elastic because the noise repeats itself. So the crack that does no harm is one that can only be done once and then takes time to occur again. While others may lead to some kind of wear and tear on your joint Many people ask about the spine.
