1. Osteoarthropathy is generally related to age and cumulative injury. Such as rheumatoid arthritis, not only the hand joints become bigger, but also other joints become bigger.
2. Trauma can lead to joint deformation and swelling. In most cases, finger joints can't recover after trauma.
3. Cumulative injury, fingers are always hard and do the same action repeatedly. In the long run, it will cause joint damage. Such as doing housework and working in a factory. Some white-collar women need to knock on the keyboard for a long time at work, which will also cause cumulative injuries.
4. Some people keep rubbing because of joint pain, because the connective tissue of the hand is relatively dense, which leads to joint swelling and is difficult to fade.
In addition, endemic Kaschin-Beck disease is also one of the reasons, which is caused by the lack of a trace element.
In view of the above reasons that may lead to the enlargement of finger joints, people should pay attention to protecting hand joints in their daily lives. For example, when cooking and cutting vegetables, don't use your fingers too hard. Clinically, I have seen patients with metacarpophalangeal joint subluxation caused by long-term chopping vegetables and holding a kitchen knife too hard. Pay attention to the combination of work and rest when using hands, appropriately reduce the movements of tired fingers, avoid excessive reciprocating movements, and pay attention to hand health care. But don't overdo it and do nothing, otherwise it will easily lead to poor blood circulation and atrophy of muscles inside your hands.
