Cracking of the finger joints
A little bit different is the cracking of the finger joints, which many people cause arbitrarily. Here, the trigger is assumed to be that overstretching the fingers creates a vacuum in the joint. This releases gases that form small bubbles inside the joint. When pressure or pulling causes these bubbles to burst (cavitation), the characteristic crackling sound is produced. Arthritis is not to be expected here either, but in some cases, if the cracking is caused too often, it will occur:
- Reduced grip strength or a
- Continuous overstretching of the tapes.
Are cracking joints harmful?
The exact reason for the cracking of joints is not yet known. However, it is assumed that these noises occur when the individual components of the joints are pulled apart and actively moved. This can lead to a negative pressure in the area of the joints.
In this context, the actual cracking of the joints should be caused by the pressure acting on the joint fluid (synovial fluid). The principle of the joint cracking can be compared to a suction cup which is first applied to a flat surface and then removed again. This also creates a negative pressure which leads to audible noises.
In the case of joints, however, permanent cracking can be harmful. In addition, there is a further theory circulating in medical circles about the cracking of joints. According to this theory, tiny gas bubbles inside the synovial fluid cause the cracking.
If excessive movements occur in the affected joints, these gas bubbles are supposed to burst and thus cause the familiar sounds.Furthermore, a functional limitation of the tendons is believed to be involved in the development of joint cracking. In general, it can be assumed that the cracking of joints is rather harmless and not harmful in the long run. This is especially true when the cracking of joints cannot provoke pain.
However, people who have gotten into the habit of having their joints cracked deliberately can impair the joints in question by applying gross force. In these cases, the cracking of the joints can even be harmful. Since cracking of joints can also be harmful and cause severe pain, patients should urgently consult a specialist and have their joint status checked.
Under certain circumstances, the pain when the joints crack may indicate the presence of arthritis. Arthritis is an inflammatory joint disease that can lead to significant wear and tear. In some joints, regular, deliberate cracking can also have a harmful effect on the menisci. People who suffer from frequent cracking should consult a specialist to rule out a serious disease.
