In life, many people like to break their fingers off easily, especially the primary and middle school students. In front of other people’s fingers out of the “cut” sound, feel very sour, think that this is both a skill, but also can show off.
But have you ever wondered why a finger break sounds like a “ka-kha”? What harm does a person bring to breaking fingers in a sour way? Let’s get to know.
Why do fingers ring?
There are many theories about the bouncing caused by finger breaking, among which the bubble theory is the most popular. The theory suggests that the sound emitted by the knuckles is related to lubrication and the presence of carbon dioxide bubbles in the synovial fluid that buffers the joints.
There are two main reasons for the sound of a finger break:
The physiological bouncing of the fingers.
Physiological bouncing has its mechanism. To put it simply, a physiological bounce does not cause any pain or discomfort in the knuckles.
Physical bounce is generally not a problem, so don’t worry too much. All you have to do is observe.
For example, osteoarthritis of the finger, tenosynovitis of the finger can cause the elasticity of the joint between the fingers, this kind of bounce is caused by the lesion of the finger.
The finger osteoarthritis is the finger cartilage degeneration, the bone proliferation, causes the finger joint friction resistance to increase, thus causes the spring. Tenosynovitis is a local inflammation caused by the compression of the flexor tendon of the finger, which causes a bounce.
Pathological bouncing, need to let finger rest brake as far as possible, avoid the occurrence of bouncing. Want to treat primary disease commonly, had better go to the hospital to see, combine doctor’s physique examination, deal with further next.
Will breaking fingers lead to arthritis?
There is a certain relationship between the two, but the proper physiological bounce of the interfinger joint will not cause arthritis between the fingers, nor will it cause other problems in the interphalangeal joint.
However, some people like to break the fingers out of some bounce, and think these moves are very cool. Some people are even addicted to bouncing, making their fingers bounce every day. Be sure to pay attention to the proper amount of bounce between the fingers.
What harm is there in finger breaking?
From a medical point of view, bouncing itself is actually a kind of friction. Moderate bouncing is not harmful to the joints, but the incidence of bouncing is high, and friction increases, which slowly produces chronic inflammation between the fingers. It can also slowly lead to arthritis between the fingers.
Even if the physiological sound, but also to grasp the appropriate amount. Because once the physiological bouncing increases, or artificially makes the physiological bouncing greatly increase, it is easy to lead to pathological bouncing eventually.
So, break your fingers in moderation.
