Crunch in any joint is a fairly common phenomenon. There are many people who have a habit of crunching fingers. They receive pleasure from it, and the people around them are irritated. Meanwhile, many think: is it harmful to crunch fingers? There is no definite answer to this question. Opinions of specialists were divided. Some argue that it is possible to crunch your fingers and needed, others are inclined to the danger and harmfulness of this classes. So let's understand.

Causes of phenomena

Let's start with the fact that the joints are cristed - the habit of causing addiction. And before answering the question, it is harmful or not, let's find out: why the fingers crunch. According to experts, the desire to click the fingers arises due to excessive statistical stress in the brush. In each joint of the human body there is a synovial fluid. It provides the elasticity and mobility of the joints, because it is natural lubricant for them. Thanks to this fluid, the joints do not rub each other, but silently slide when driving. The composition of the synovial fluid includes carbon dioxide, nitrogen and oxygen. When crunching, the joint capsule is stretched, its size increases, and the pressure drops. This leads to the appearance of gas bubbles that are collapsed, causing a characteristic click. After about 15 minutes, the gases again dissolve in the synovial fluid and the click can be repeated. There is nothing dangerous or harmful in this.

The second cause of the crunch is as follows: in the process of movement, the smoke and crackle arise due to excessive tension of ligaments and tendons. When the articular capsule, bundles and tendons are tensioning, the joint becomes overly mobile and the person feels relief.

Points for and against

Let's consider the arguments of the second group of specialists who talk about the dangers of crunch.

The first argument. Crunch in any joint (interphalangeal, cervical or lumbar) brings him in incommensurable harm. It looses and destabilizes the joint, which can lead to displacement of the elements of the joint, provoke dislocations, subluxances and infringement of the nerves.

The second argument. Counting and joints Falangi are very vulnerable. They are subject to rapid destruction and inflammation, so over time, arthritis and arthritosis of the brushes will arise.

So, I realized that threatens the owners of this harmful habit in the future, we turn to scientific research. In medical circles there is such a concept as evidence-based medicine, which is based on effective evidence facts. Thus, to prove the "harm" of the crunch, it is necessary to conduct relevant research.

Several modern researchers tried to figure out the negative consequences of the crunch. However, no scientist was able to detect convincing evidence that lovers of "hurt" somehow harm their health. If a person does not have the pathology of the joints of the hands and they are healthy, then the crunch is completely harmless. Surgeon - orthopedist Pedro Berezhiklyan noticed that the habit of crunching the joints is so common that if it caused harm to joints, then every second person sick arthritis or arthritis. However, the etiology of these diseases is completely different.

American doctor Donald Unger spent a very interesting experiment. At the end of the experiment served his own mother, who constantly told about the dangers of crunch. The doctor Dr. Unger loved to do this, and he crunched only with his fingers on one hand, never tried the second. And so, when the doctor turned 80 years, after 60 years of research, the conclusion was made, which will forever put the point in this matter. Both hands were in the same good condition, although he crushed his fingers only on his left hand. Dr. Ungher made verdict: criste with fingers is not harmful! The doctor even received a premium on medicine for an experiment conducted on himself.

Despite the study of Dr. Unger, many doctors, like many medical sources, argue that crunch is very harmful. What can I say? It is worth considering their health carefully. If the crunch is the usual thing for a person and accompanies it from childhood, it is not necessary to worry and abandon this reason. But if the crunch is accompanied by painful sensations, swelling, restriction of mobility, then, of course, a certain pathological process takes place. In this case, a doctor-rheumatologist is needed.

For those who want to get rid of dependence

There are a lot of people who are annoyed by crunching their own fingers. In this case, it is necessary to take measures to get rid of this dependency. Leading specialists in the field of orthopedics offer to get rid of these habits with dynamic exercises for hands and brushes.

To do this, follow the following exercises:

1. Rotation of brushes and fists. First you need to make rotational movements with brushes, then squeeze them into the fist and rotate the fists.
2. Break hands, and then vigorously shake them, as if the water from the tips of the fingers. Then, in a relaxed form, lower hands down.
3. By connecting the fingers into the castle to perform a smooth movement - a wave. Exercise 4-5 times.
4. Connecting hands above his head in the castle, raising and lowering them. Perform 2-3 times
5. Squeeze alternately all your fingers starting from the little finger and ending with great. Exercise two - three times. Repeat 4-5 times.
6. Cross the phalanxes like scissors, that is, apply one to another. Make 2- 3 approaches.
7. Clicks. Fold your fingers as it were for clicking on the forehead. Repeat several times.
8. Healing salt baths for brushes. In warm water, stir the sea salt and keep your hands in this water for about 15-20 minutes.
9. Eat products with high calcium content, as well as products that strengthen bones and cartilage. Milk products and a variety of students are very useful.

If you want to "hurt" with knuckles, these movements will help distract human.

Crunch in the joints is the sound of "cracking" character arising from passive or active movements. Most often, the crunch occurs with intentional flexion (pulling) fingers to the least. Crunch can occur in many joints, such as spine, thigh, wrist, elbow, shoulder, fingers, knees, jaw and others.

Why does this crunch and crack appear? Is it harmful to do that?

The reasons for this crunch were the subject of controversy in medical literature at least since the 1930s, but the consent between scientists was not achieved. In 1947, British researchers first put forward the theory, according to which the cause is in the joints of "empty bubbles". At the moment when the contact between the surfaces of the bones in the joint disappears, the pressure of the synovial fluid drops, and the gas dissolved in it is released into bubbles, as bubbles appear in the opened bottle with carbonated water. The hypothesis explaining the crunch of fingers appeared in the gas bubble joint was put forward by two more doctors from the Hospital of St. Thomas in London, conducted experiments using an X-ray apparatus.

Studies have shown that the synovial fluid contains quite a lot of dissolved carbon dioxide (approximately 15% of the total). And in 1947, Wheeler Haines suggested (using confirmations obtained by radiographs) that clicking arises due to the sharp formation of the gas cavity, which create an opportunity for a sudden expansion of the amplitude of movement, which generates sound. However, with the help of a high-speed camera, it was shown that bubbles fall again in 0.01 seconds after occurrence. Later, for a long time it was believed that the gas bubbles accumulating serves as the crunch of the joint. Since not all gas bubbles collapse, it is necessary for some time on its complete dissolution (approximately 15 minutes) in the synovial fluid, also time is required in order for the articular surfaces to come together (cavitation effect is possible). For example, when pulling a finger, a vacuum is created in the Metal-Falangie joint, the gas cavities are suddenly formed, which are then instantly falling down, which generates vibrations that are transmitted to surrounding tissues.

Canadian researchers with the help of magnetic resonance tomography managed to answer the question why the crunch is heard, if they pull the finger. This time, scientists under the guidance of Professor Gregory Kuchuk (Gregory N. Kawchuk) from the Unbetta's university in Edmonton resorted to the achievements of the XXI century technology. They built a device that made it possible to pull the finger while the brush hand was in the tomograph. Tomograph fixed the process at a speed of 3.2 frames per second.

As a result, it was possible to establish that the cause of sound is the phenomenon that physicists is called tribonucleation. Cavitation (or tribonucloration) is the formation of small gas cavities in the joint, which are capable of dramatically increase the amount of intra-articular space.

When two solid surfaces are immersed in a liquid containing dissolved gas, their compound and separation can cause the appearance of small gas bubbles. In the technique, the tribonucleation is observed, for example, in bearings. In the case of a crunch, the bones surrounded by the synovial fluid, which filled the joint cavity is filled with the fingers as solid surfaces.

In each case, the crunch and "discrepancy" of the joint was associated with the rapid appearance of the cavity filled with gas, the bubble in the synovial fluid is an exceptionally slippery substance that moisturizes the joints. When the surface of the joint suddenly "diverges", the fluid becomes not enough to fill the volume of the joint, therefore the cavity is created, and this leads to the formation of sound.

The behavior of Gregory Kurchuk compares with two glued glass plates applied to each other. They are very difficult to divide, as the water film between them creates resistance to overcome. That is, the sound that makes tape, if you wear the ego from the wall, then it causes this sound.

And its cause is the cavity rapidly formed inside the joint. The working title of the study ("Pulling me for a finger") reflected its essence - this is exactly what was the observation, which was recorded with the help of MRI and showed what was happening inside the joints. To search for answers, the learning group needed someone who could crunch knuckles on request, since most people who are "crunchy" can always extract crunch of all fingers and after standard respite to do it again. The test fingers alternately placed in the tube connected to the cable, which was slightly pulled to the crunch in the joint. The crunch was fixed on MRI in real time and took place every 310 milliseconds.

In 2015, the MRI scanning group conducted by the group of scientists in real time showed that it is the moment of the formation of bubbles in the synovial fluid that causes a click, and their decrease occurs silently.

Conclusion

1. Crunch is absolutely normal, there is no harm. But benefits too.

2. "The ability to crunch knuckles can be attributed to the health of the joints," says the author of the Cauchak research.

3. Does not cause arthrosis. Popular view that crunch is deliberately harmful and can cause various diseases of the musculoskeletal system (arthritis, osteoarthritis). A recent X-ray study for 215 people showed that there are no differences in the risk of joint diseases in people who crush their fingers and not. It also does not matter the frequency with which this manipulation is performed.

3. Without panic. If the crunch in the joint is not accompanied by pain, edema, increase in temperature, then there are definitions for panic. If any of the named symptoms are present, you should consult a doctor.

4. Schnobel. Dr. Donald Unger conducted his own experiment. He crunched with my fingers only one left hand every day for 60 years, after which no differences in the brushes were revealed. The scientist received the so-called Shnobelevskaya (not Nobel!) Prize for this work in 2009

5. The desire to hurt. If the crunch causes discomfort, or the desire to crush the joint occurs as a way to remove the unpleasant sensations in the joint, it is worth finding a specialist who can estimate the functional state of the joints (usually the assessment of biomechanical chains, and not one joint) and muscles participating in their movement (orthopedist, doctor LFK, rehabilitologist, competent fitness coach). A permanent desire to surrender speaks of numerous muscle spasms.

6. Neurotic crunch of poliet. In another study, they found that the habit of crunching the knuckles of fingers can correlate with the presence of such habits, like smoking, alcoholism or passion to nibble nails on hand, i.e. Wear a neurotic or stressful character. This is also worth paying attention to.

Although of course criste with fingers, knees, neck, spine is not the same thing. All due to the fact that the spine contains more nerve endings that are easy to pinched.

Crunch in fingers - A common phenomenon of almost all age categories of people. May be observed from infant age to deep old age.

Causes of crunch are diverse, let's call the most common:

• Strong motor activity provokes excessive stretching of the ligament, joints and bones;
• Sedentary lifestyle leads to atrophy not only muscles, but also a bone skeleton;
• Voltage joints It occurs with long stay in one position;
• Congenital pathology of the joints, When the joints are located freely relative to each other, clicks are heard when bone discrepancies and return to its original position;
• Unlimited wearing weights;
• Crunch may indicate About joint diseases: Bursitis (inflammation of the synovial bag), tendinitis (inflammation of tendons), arthritis (inflammation of joints), arthrosis, rheumatizes of others. In this case, the crunch will always be accompanied by pain;
• Injured There may also be a cause of crunch;
• Salt deposits, salt contributes to harvesting the cartilage, reduces the elasticity of the tissues;
• Disadvantage calcium, liquid;
• Bad habit for removing emotional stress, if necessary, focus on any process, making important decisions;
• Mental disorder Various severity.

The human bone system is designed specifically for movements. But any load should be moderate and reasonable for a particular body.

Norm

The norm is a natural crunch or physiological, which is observed when driving, movements, sharp turns, exercise. As a rule, such a crunch is practically not heard.

And if it occurs, It is useful for the joints, as it happens the necessary, natural relaxation of the bone skeleton and muscles. If the joints, cartilage, tendons are in a healthy state, then even during croaks and other natural stretching, the crunch should not be.

Crunch can be the normwhen it occurs during exercise, or after tension, if it is not accompanied by pain symptoms, swelling, stiffness of movements, redness and other unpleasant symptoms

Pathology

Pathological crunch Delifies pain, swelling appears, swelling is signs of deformation of the joints.

If it is a symptom of the disease or hereditary pathologies for the development of the joints. Diagnose disease or pathology can only qualified orrtoped or surgeon.

When the crunch of fingers is not a symptom Diseases or pathology, and a lover of crunch thus manifests itself, trying to draw the attention of others or crushing precisely during nervous tension. A man with sore joints is unlikely to appease with fingers.

The desire to child for the public testifies about a possible mental disorder. After all, you can find more adequate ways to express your personality. And drug therapy may also be shown. The consultation of a psychotherapist doctor will help in solving this problem.

The mechanism of the occurrence of the crunch in the fingers

In 1947, Canadian scientists conducted a study on the mechanism of the appearance of a crunch in the fingers. The tests were carried out on volunteers who stretched the fingers to the crunch and at that moment were fixed in the joints with MRI.

The conclusion was the following: With natural or artificial stretching of the joints between them, the pressure drops sharply and the cavity is formed, which is filled with bubbles of gases, with a sharp flexion of the joint bubbles burst with specific cotton.

Orthopedopian doctors believe that the crunch occurs as a specific reaction of joints and tendons for sharp bending

The benefits of Crush

In a medical environment there is no consensus about the benefits or danger of this action. There is no speech about the benefits at all. Some scientists and doctors express not about the explicit benefit of the crunch, but about his harmless effect on the human body.

Allegedly lovers to hurt thus make tension, relax, and no threat to health brings.

A known example of a California doctor, who crouched one hand with fingers for 60 years, and after 60 years did not notice the difference between his hands.

That is, both hands were healthy. But this is a single case. Making global conclusions on his basis would be unreasonable. You can talk about the benefits of a crunch in the case when it accompanies morning squeezing and charging, or after a long work in one position.

The cutting muscles and the ligament apparatus are stretched and thus removes the voltage. Or with long work on a computer, you need to unload your fingers.

Her harvest

Most of the doctors and scientists speak about the obvious harm of the crunch. Proving that the uncontrolled crunch leads to the deformation of the brushes, the loosening of the joints, the deficiency of the synovial fluid, infringement of the nerve endings, dislocation, sublifting, swelling and eradication, inflammatory diseases of the joints.

It is precisely known that a systematic crunch leads to the fragility of the joints, and this may lead to more serious consequences. But the aesthetic side of the question: The crunch definitely causes a repulsive impression, causes doubts about the adequacy of the amateur incentively criste.

Consequences of crunch

As you know, each organism lives and develops according to its individual laws. Assume whether there may be the consequences of a crunch or no no one can. If you specifically hurt your fingers several times in life, then nothing terrible will not come out of it.

But if it goes into a habit for many years, then surely can most negatively affect the state of the joints. A constant unnatural load on the articular mechanism cannot pass without a trace.

The articulated and the bunder will be destroyed very slowly, throughout life: first loops, loses elasticity, cracks appear, there is a deficit of the joint liquid, from which the joints are drunk on each other. Causes pain

And all this leads to serious inflammatory diseases of the joints. In young years, no consequences of bad habits are not visible, reaping the fruits of their thoughtless actions will have to be in a mature age. If there is at least a small share of risk for health, it makes sense to think whether it is necessary to root your health.

How to get rid of this habit?

If scientists still argue about the benefits and the harm of the crunch would be reasonable not to put experiments on their health. And do not annoy other people an unlimited crunch.

If the doctors diagnosed that the crunch is not a symptom of a disease or pathology, but a bad habit, then it is necessary to gradually refuse this habit. The main thing should be desire.

It is possible to replace the crunch on:

• Massage of fingers, gradually rubbing each finger from the tip to the base;
• Distracting maneuvers Collect Rubik Cube, twist pen or balls in hands;
• Charging for brushes, Compression and straightening of fists, rotation of the brushes clutch together, alternate bending and extension of fingers, relaxation of brushes by shaking;
• Baths with sea salt or chamomile extracts, sage, pine;
• Swimming. Wonderful sport, which is shown in various diseases, primarily bone apparatus. Also relieves psychological tension, relaxes muscles, strengthens immunity.

Prevention of crunch in fingers

Of particular importance, the complex of preventive measures is useful for people with hereditary location to diseases of the joints, athletes and all wishing to preserve the painless mobility of the bone skeleton to a deep old age.

Denote the main events:

• Healthy nutrition Be sure to include food rich in calcium;
• Follow weight overweight loads bones and joints over measures;
• Eating required quantity fluids, in summer to three liters, in winter to two;
• Move more, movements block congestion in the bone system;
• Safe sports, choose the sport that will benefit the body;
• Avoid injury and severe physical exertion.

The answer to the question - It is possible to crunch your fingers on your hands, it will be like this: yes, you can, but first appreciate all the likely risks for your own health and peace of mind.

During movement, the various elements of the joint move, which often causes a variety of sounds similar to crunch or crackle. Most often "sound" knees, spine and ankle. Separate people can crunch the joints of the fingers and brushes.

What causes crunch in the joints?

Most often crunch in the joints, is associated with increased mobility. This is called hypermobility. Most often, such an innate state occurs in young women, since they are produced in the body a changed collagen - more stretchable. This leads to a change in many tissues, especially joints.

Movement of ligaments, joints and tendons. During the movement, the position of the tendon is changing. When the tendon is returned to its place you can hear clicking sound.

Accumulation of gases in the joints. The joint contains a synovial fluid that performs the lubrication function. Nitrogen, oxygen and carbon dioxide are dissolved in this fluid. At the moment of coloring the articular bag or unnatural movement, the gases are collected in bubbles that burst, and cotton is heard.

Inflammation. In the occurrence of inflammatory processes in the joints, the coincidence of the articular surfaces may be disturbed, which causes a click.

Arthrosiswhich occurs when the "wear" of the joint, when cartilage is thinned.

Uneven surfaces of Sustav. With the loss of smoothness of cartilage, rough surfaces make sounds.

Salt accumulation. In the joint, scored salts, the elasticity of bundles and tissues can decrease. It can also cause crunch when driving.

Is the crunch in the joints?

Most experts tends to treat joints when the crunch is accompanied by unpleasant or painful sensations. Most likely, this may indicate the expanding of bone tissue.

The hypermobility of the joints is often accompanied by varicose veins, since their walls include a large amount of collagen. People with such problems should not choose a job that requires a long stay in the same position. Especially harmful, with changes in collagen, stand for a long time.

If the crash and crunch accompanies movements in the joints of the spine, the ankles, fingers or knees, and there are no painful sensations, it is likely not to worry. The structure of these joints, ligaments and bones around them is such that, even a minor movement, can cause crackle, with absolutely healthy joints. Ankle, for example, consists of three bones, and vertebrae is sedimed.

Prevention of joint problems

Very often crunch, and then diseases in the joints appear as a result of a low-lifestyle lifestyle. When working, which requires a long stay in one position (sitting or standing), you need to enter the rule: every hour and a half, get up and move. If, for example, the teacher is so worth it, it makes sense to teach himself to walk, or at least regularly transfer the weight of one leg, allowing you to relax and relax the other.

You can enter a fashion at the "production gymnastics" in the office: get up, perform turns of the head, rotate with your hands, move your shoulders, squeeze several times the fists.

It is desirable to carve two or three times a week to exercise sports. It should only be remembered than a more traumatic sport, the more problems with joints may occur. The best prevention option is swimming.

People with overweight always have more problems with joints, feet and spine suffer especially often. In this case, a decrease in weight (diet, exercise) will reduce the burden on the joints.

If you correctly choose physical exercises, you can stop arthrosis in the early stages and even stimulate the growing cartilage tissue. Sport classes help improve the blood supply to the muscles and fabrics that surround the joint, provide delivery to oxygen cartilages and restore metabolic processes.

How to deal with problems in the joints?

Doctors can designate chondroprotectorsIn the event that arthrosis detects. These preparations are usually containing two active substances - chondroitin and glucosamine. Portability and effectiveness are high enough. These drugs help slow down the natural destruction of the joint, thereby contribute to the increase in cartilage tissue in the joint.

Together with chondroprotectors, very often prescribed vasodilatory drugs, to improve blood supply in the articular tissues.

Useful may be a course salt baths. In hot water, salt rich in microelements can be added with plant extracts (sage, chamomile, pine). After the bath in the joints, fir oil can be labeled.

To prevent problems with joints, you can undergo a wellness course in sanatoriums Matsesta, Evpatoria, Pyatigorsk, Odessa. Mud and healing baths can significantly improve the state of the joints. As a last resort, you can use therapeutic mud or rape purchased in the pharmacy.

If, besides the crunch and cod, in the joints regularly appears painful syndrome, then it is necessary to urgently consult a doctor.

Disputes on this issue as much as disputes, on the topic "who was before the chicken or egg"! If you wish, you can find a lot of articles proving that this is a completely harmless habit or on the contrary, a dangerous procedure, with the consequences of which you will encounter in old age. Many can calm you down, while others on the contrary scare arthritis. "So criste or not criste?" you ask. Let's look at the versions for and against the crunch fingers together.

You can read the opinion of the harm of the crunch with the fingers of very many elderly, authoritative people, for example, such as California, Donald Unger. In his books and publications, he mentions that since childhood, from day to day, crusher knuckles left hand. Naturally, heard a warning from his mother very often, which in old age will be waiting for arthritis. But survived to 83 years, it claims that the sensations in his right and left hands are the same. From his point of view, the sound that we hear with the crunch of the fingers is just the span of gas bubbles. And we stimulate the tendons, we relax the muscles and weaken the joints. But then I want to ask a question to the respected Mr. Donald Unger. If, as he claims, the crunch fingers are not only harmless, but also useful, then why in old age his hands in the same condition? Shouldn't his left hand feel better than the right? Do not forget that Donald Unger received his premium on medicine not for the proof of the harmlessness of the Hrush's habit of his fingers, and for the experiment spent on himself!

And on the contrary leading orthopedists persistently do not recommend crunching fingers. Doctors agree with the conclusion that the sound that we hear, with a crunch of fingers, is bursting bubbles of gas. But I want to figure it out what kind of gas and where bubbles come from in it. When a person crunches with his fingers, it dramatically reduces the pressure in the intermediate liquid and the gas located in it highlights bubbles, and they in turn are bursting and we hear it. Over time, everything will fall into place, but as long as it occurs, the balance of the intermediate liquid is disturbed in the joints of the fingers and, because of this, the joints are "separated. If you "hurt" with my fingers - the top three times in life there will be nothing terrible, but if you do it all? At first, you may not feel harm from the "loosening" of the joints, but after 8-12 years of this fellow habit, you will notice that the joints will begin to swell, and the fingers acquire the ugly shape. With prolonged crunch, you can destabilize the joints, and this in turn can provoke dislocation and pinching of nerve endings, and then lead to inflammatory processes in the tissues. And the next step will be the appearance of arthritis.

Famous doctors Castellanos J. and Axelrod D. When writing your book " Chronicle of rheumatic disease"(1990) conducted studies on the influence of the crunch of fingers, on the basis of X-rays, prove that this habit leads to the swinging of the joints and deformation of the fingers.

Leading experts orthopedic and traumatologists in the event of the need to "hurt with fingers" offer to replace this procedure with dynamic exercises or pamper your fingers with baths with the addition of sea salt.

Dynamic exercises for the joints of the fingers:
1. Bend and instill your fingers in a fist, do not forget to strain your fingers when performing this movement. Do this exercise should be 4-5 times.
2. Imagine that you click someone on the forehead. Such virtual clicks should be performed by each finger. Do this exercise follows 2-3 times.
3. Squeeze, in turn, fingers starting from the little finger and ending with a thumb, then we do the opposite. Do this exercise follows 2-3 times.
4. Perfect the fingers to the manner of the "scissors" exercise. Do this exercise should be 4-5 times.
5. Connect your fingers into the "lock", lift them above your head and dramatically lower them down, each separately. Do this exercise follows 3-4 times.
6. Connect your fingers into the "Castle" and expect the "wave". Do this exercise should be 4-5 times.

These are such simple and painless exercises will replace crunch fingers. But if the exercises help fingers, unfortunately, to get rid of the habit, they will not help. Try to divert yourself when the desire arises to hurt your fingers. To begin with, you can simply dissolve your hands, if it did not help, move small balls between your fingers or a handle, and even better, buy yourself a ruby \u200b\u200bcube and collect it in the event of a desire to hurt with your fingers. And it should be remembered that at the young age get rid of the harmful habit of much easier than in the elderly.

In the comments, tell us, whether you annoying when someone clicks the joints of the fingers or maybe you yourself have this strange habit.
