If you have nothing to do, do you often unknowingly pinch your fingers?
Many people say that they must also loud.
But have you ever thought about: Why is there a sound with your fingers? Can you cause arthritis or big fingers to often be jealous of your fingers?

Today, let's learn it.
01
What happened when I stabbed my fingers?
First, let's take a look at the structure of our finger joints. It is a cavity surrounded by cartilage, ligament, and sloling membranes. There are a small amount of transparent viscosity liquid in the joint cavity. This is called sliding fluid.
When joint activity, in addition to the bones in movement, the surrounding ligaments also protect the stability of the joints at all times. The sliding fluid in the joint cavity is like "lubricating oil", making the joint movement more freely.
As for the sound of the fingers, the burst of bubbles is the most common explanation at present. When you slap your fingers, negative pressure in the joint cavity, the gas in the slider exists in the form of bubbles, and the bubbles will make a "click" sound when it is squeezed and ruptured.
Of course, there are some different views.
In 2005, the Canadian scientific research team used professional equipment to conduct a dynamic nuclear magnetic resonance scan. They found that when the fingers joints were filled with sliding fluids, when the fingers were pulled, the sliding fluid also made corresponding changes. This During the process, gas will appear in the slider and form air bubbles in the sliding fluid. Until the fingers make a "click" sound, this bubble will exist.
Therefore, they believe that the sound of the sound when the fingers are lying down are not caused by bubble rupture, but are related to the formation of an empty cavity in the joint.
When the joint is held, you can see that the black color in the joint cavity forms a black color formation

In addition, from the experiment, it was found that during the process of the joint, the bones and bones were not exposed. Therefore, the sound of the finger appeared was not caused by bone friction.
I believe that in the future, scientists will definitely find the real source of the sound of their fingers.
02
Do you often get your fingers?
When lying on the fingers, there is no friction between the bones and the bones. Therefore, in general, the harmfulness of the fingers of the finger opponent's fingers is not great, and it will not cause the fingers to become thicker and arthritis.
The funny Nobel Prize winner Donald Origer once tested it with his body. In the past sixty years, he only scratched his left hand joint and never stabbed his right hand.
Sixty years later, his conclusion was that he would not like it.

In 2011, some researchers conducted a retrospective research on the correlation between fingers and arthritis that long up to five years. The research was included in 135 experimental groups and 80 control groups. The results showed that finger and arthritis It's ok.
However, in some specific cases, frequent fingers may cause damage to the opponent's finger.
03
In what circumstances, the fingers are harmful?
In 1990, a study abroad showed that frequent fingers may cause hand functional decline. In addition, frequent fingers may also cause the hand tendon ligament damage and need surgery.
In 2015, a literature reported that a 24 -year -old man was admitted to the hospital for a long time and frequently. After inspection, it was found that the small finger extensor tendon and the dorsal side supported damage. When the small finger joint bending exceeded 50 °, the small finger joint would be dislocated, and the surgery was finally recovered.
In addition, when the fingers are injured, especially when the finger has ligament damage, the finger will increase the ligament damage. It may make the fingers thicker, the finger joint becomes unstable, and it is prone to arthritis in the long run.
Therefore, there is no major harm to pinching the fingers, but when the fingers are injured, the fingers will become harmful when the fingers are injured.

What is the problem with your fingers thicker?
Under normal circumstances, there are two reasons that will make your fingers thicker.
The first is the degeneration of the finger joints, that is, the cartilage of the finger joints.
Bone hyperplasia appears around the joints, and the joints around the joints will become thick. It is common in users with frequent users. It is usually not uncomfortable when you are young, but over time, when you are old, your fingers will feel uncomfortable.
In addition, there are autoimmune diseases, such as internal rheumatoid arthritis, which will cause the cartilage of the finger to be eroded by the immune system, which will cause the fingers to be thick and even deform.

The second is caused by damage to soft tissue.
For example, when playing basketball, when you poke your fingers, causing the side side -by -side ligament damage of the finger joints, the swelling of the finger will become thicker. At this time, the opponent's finger will be fixed for about 3 weeks. It is difficult to fade with thickening fingers, and it will even affect the activities of the finger joints.
In short, no matter what kind of reasons, the fingers become thicker, everyone must pay attention to it and go to the hospital for examination and treatment in time.
