The pleasure of some to crack their joints is a torment for many others. However, the “cracker” hurts himself and his neighbors are not the only ones to pay the price for his habit.
“There are many people who like to crack their fingers or their neck, which is mainly linked to a certain tension in the muscles. This tension leads to an irresistible desire to make them crack. But when someone does it 20 or 30 times a day, it’s more like a neurosis and looks like the bad habit of biting your nails, “trauma specialist Constantin Ternovoy told Sputnik.
Thus, the “crackers” contribute greatly to the aging of their joints, he noted.
“Repeated creaking of the joints in the hands and neck leads to instability and the joints loosen which, in turn, leads to faster deterioration and osteoarthritis. If you take care of your dilapidated joints, you will have osteoarthritis at 50 that you should only have at 70, “he said.
Constantin Ternovoy added that it was possible to remedy this bad habit with a simple massage. As for the regular “crackers”, he advised them to turn to a shrink instead.
Why and how
In the meantime, scientists are still trying to establish what caused the noise of these crackles.
According to a study published in the journal PLOS One in 2015, the origin of noise lies in the creation of a kind of cavity. During an MRI experiment, it turned out that the noise corresponded to the sudden appearance of a gas bubble in the middle of the synovial fluid, the one found at the level of the joint spaces. When you pull on the joints, there is not enough liquid to fill the space and a cavity is formed.
However, other researchers have looked not at the practice, but at the mathematical model simulating a cracked join. Their study published in 2018 in the journal Scientific Reports claims that the famous “crack” still comes from the bursting of microscopic bubbles in the fluid of the joints and not from their formation.
