Holding a mobile phone for a long time with little finger will lead to finger deformities?
The description is so vivid that it seems to be immersive. Can you believe it?

The first step in spreading rumors is to trace back to the source.
The picture is making up a story, but it doesn't exist? Japanese netizens who were scared to pee? The original source of the picture is a tweet published by NTT DOCOMO (Japanese: NTTドコモ), Japan's largest mobile communication operator:
This Japanese translation into Chinese means:? Finger deformation! ? The harm of holding a smart phone? . Don't put all the burden on a specific finger, often change the posture of holding the mobile phone or have a rest. ?
This passage means to remind smartphone users to rest their fingers at ordinary times. No relevant links or research support opinions were given, and the source of the picture or the events that caused the situation in the picture (such as the size of the hand, the weight of the mobile phone, the playing time, etc.) were not explained. ). So, regardless of making up stories, is it possible to hold your mobile phone with your little finger frequently, which will lead to finger deformities?
The second step of dispelling rumors is scientific argumentation.
Although people usually hear more about the prominent importance of the thumb, in fact, the little finger is also extremely important to human beings. As early as ancient times, the little finger played a key role when human ancestors made and used stone hammers, axes and knives. 1998 paid special attention to the activity level of upper limb muscles when making stone tools. Research shows that the little finger plays a key role in keeping the stone stable when making stone tools. In the process of making stone tools, the muscles of thumb, index finger and little finger use the most strength.

Little finger's main job (from ancient times to the present) is to keep balance and hold things firmly in his hand. Just like our ancestors, little finger does the same job when we hold mobile phones. According to research, the smaller the object you hold, the less the function of the little finger. That's why if you want to pick up a small teacup with a handle, your little finger will even tilt up. Nowadays, smartphones with larger screens are a bit heavy for human hands, so the little finger is becoming more and more important. You must hold the bottom of the phone like a bracket.

If you keep the same gesture for too long, the little finger will hurt, but this phenomenon is called repetitive strain (RSI), which is popular in desktop computers? Mouse hand? The principle is the same, that is, repeated actions for a long time lead to functional pain or injury of specific bones and muscles, but it has nothing to do with bones. True deformity refers to another disease, called congenital scoliosis, which is caused by problems in bone growth and development, and the incidence rate in the population is about 10%. However, few people really treat or even find themselves with this disease, because it will only affect the normal function of the hand if it is serious enough, and usually no one will pay attention to it.
Conclusion: If the little finger in the rumor photo is normal without deformation, the depression is a temporary deformation caused by holding the mobile phone for too long, and it will recover after a short rest. However, NTT DOCOMO's original intention is good. Don't stare at the phone all the time, let the brain, eyes, cervical vertebrae and fingers have a good rest ~
