According to the current state of research, cracked fingers are not considered dangerous and are not a possible cause of diseases such as arthrosis or arthritis.
“Studies have found no difference in the incidence of disease in subjects who crack their fingers. Swelling, less grip strength and slightly higher mobility fingers, only shortly after the crunch”,– says family doctor Tatyana Zakharova especially for the MedikForum
Hence the crunch in the fingers
Crack or crunch in the fingers is caused by the release of gas bubbles into the synovial fluid surrounding the joints. This acts as a lubricant in the joints and makes them more flexible.
Synovial fluid contains dissolved gases, including nitrogen. When you spread your fingers, for example by spreading or straightening your fingers, the pressure in your joints is reduced. This allows dissolved gases to escape from the liquid and form small gas bubbles.
A characteristic “popping” sound occurs when these gas bubbles rapidly collapse or explode.
After the synovial fluid returns to normal pressure, it takes some time for enough fluid to build up again. gas to make a crackling sound.
“Researchers investigating this issue using MRI machines have found that bubbles don't have to burst in order to crack. The sound can also be caused by synovial fluid rupturing, causing the vesicles to resonate.”
