How many of you have never, not crunched fingers or any joints during squats, swings hands or during tilting? I doubt that such exist. What is that Crunch? If he's dangerous and what to do to disappear, today we will try to answer these questions.

"What's that Crunch? Is it dangerous? How to treat?"

Crunch in the joints - is the sound that occurs when passive or active movements. It appears with deliberate flexion (pulling) the fingers into the end position. The crunch may occur in many joints such as the spine, hip, wrist, elbow, shoulder, fingers, knees, jaw, and others.

Reasons. The exact physical mechanism is, oddly enough, is still poorly understood. To explain the crunch in the joints put forward the following theories and causes:

1.) Cavitation - the formation of small gas chambers in the joint, which are able to dramatically increase the volume of the intra-articular space. Previously it was thought that the bubbles of dissolved gas with a sharp passing between the articular surfaces can cause the sound, but now it is proved that they are the result of disease, not the cause.

2.) Crackle appears when moving the ligaments, bones protruding sections (most commonly the shoulder, hip and wrist) - is a deaf character. Less sound is generated by stretching of the ligaments and rupture of intra-articular adhesions (of adhese).

3.) Well, the damage to joints as a consequence of injury or disease: arthritis, osteoporosis, osteochondrosis, etc.

Harm . It is popular opinion that crunching deliberately harmful and it can cause various diseases of the musculoskeletal system .

Recent x-ray study of 215 people showed that there is no difference in the risk of joint disease in people who crunch with your fingers and not. It also doesn't matter the frequency with which you perform the manipulation.

Dr. Donald Unger conducted its own experiment. He crunched fingers of only one left hand every day for 60 years, after which there were no differences in the brushes. The scientist has received a so-called IG (not Nobel!) the prize for this work in 2009.

Another study showed that crunch the toes leads to swelling and weakening of the power grip.

    Pathological the crunch is different from the physiological the following features:

-Does not have a refractory period;

-Occurs with each repetition of the movement;

-Is accompanied by pain;

-Restriction of movement;

Causes of pathological crunch:

Pathological the crunch in joints is often caused by the violation of congruency of the articular surfaces as a consequence of the destruction of cartilage in diseases such as osteoarthritis, osteoarthritis, etc. In these cases, often crepitus (creaking), pain, swelling and increased local temperature. According to MedicineNet , the cause may also be bursitis - inflammation of the bag surrounding the joint. Tendonitis - inflammation of tendons. Most commonly affected are the lesions of the shoulder. Crunching the knees is often associated with damage to the meniscal and patello-femoral syndrome.
