Mercola Your joints, including those in your knuckles, are surrounded by a membrane called the synovial membrane, which forms a capsule around the ends of your bones. Inside this membrane is synovial fluid, which acts as a lubricant and shock absorber so your bones don’t grind together when you move. When you “crack” your knuckles, or any other joint, it expands the space between your bones, creating negative pressure that draws synovial fluid into the new gap.
This influx of synovial fluid is what causes the popping sound and feeling when you crack a knuckle. If you continually crack your knuckles, the synovial membrane and the surrounding ligaments will loosen, making it easier and easier for your joints to crack. More than 20 years ago, I co-authored a paper titled “Cracking down on neck cracking,” which was published in the journal American Family Physician. In it, I argued that self-manipulation may lead to lax ligaments. Personally, I don’t think it’s wise to crack your joints on a regular basis, and research suggests it could have some significant repercussions. Is Cracking Your Knuckles Associated with Arthritis?
The biggest concern most people have about cracking their knuckles is that it could lead to arthritis, specifically osteoarthritis. If you have osteoarthritis, the cartilage within your joints is progressively being damaged, and the synovial fluid is typically reduced as well. The pain and joint stiffness that you feel is a result of your bones starting to come into contact with each other as cartilage and synovial fluid diminishes. To date, research has not shown a correlation between knuckle cracking and osteoarthritis in your hands. In one study of more than 200 people, the prevalence of osteoarthritis in any joint was similar among those who cracked knuckles and those who did not. The same held true when specific joint types were examined.
The authors stated: 'Total past duration (in years) and volume (daily frequency x years) of knuckle-cracking (KC) of each joint type also was not significantly correlated with OA osteoarthritis at the respective joint. A history of habitual KC - including the total duration and total cumulative exposure 'does not seem to be a risk factor for hand OA.' ' If you’re interested in lowering your risk of, it is typically caused by wear-and-tear on your joints along with lifestyle and diet factors, and aging. Repetitive movements often play a role as well, but while it would seem plausible that cracking your joints is also a type of repetitive movement, so far no link has emerged.
Habitual Knuckle Cracking Might Impair Your Hand Function While cracking your knuckles might not lead to arthritis, it does appear to have other consequences. In a study of 300 people aged 45 and older, habitual knuckle crackers were again not found to have an increased risk of arthritis in their hands. They were, however, more likely to have hand swelling and lower grip strength. They also found that knuckle cracking appears to be associated with manual labor, nail biting, smoking, and drinking alcohol they concluded that habitual knuckle cracking results in functional hand impairment.
Side Effects Of Cracking Your Neck
The damage was likely the result of the repeated stretching and loosening of the ligaments during repeated knuckle cracking. Interestingly, those researchers noted that cracking your knuckles has been shown to produce “rapid release of energy in the form of sudden vibratory energy, much like the forces responsible for the destruction of hydraulic blades and ship propellers.” This hardly sounds like a completely innocuous habit. In fact, there are reports in the literature of various injuries that have occurred from knuckle cracking, including overstretching of ligaments in the fingers, dislocated fingers, and a partially torn ligament in the thumb. Knuckle Cracking Might Be Linked to Knuckle Pads Knuckle pads are firm nodules that sometimes form over certain joints in your fingers. They’re often associated with repetitive trauma or movement, and they’ve been known to exist since ancient times (Michelangelo’s statue of David has knuckle pads).
Knuckle pads are quite common and while they don’t cause physical symptoms, they can have psychological and cosmetic effects. It seems that knuckle cracking may play a role in at least certain cases of this condition.
There is at least one reported case of knuckle pads in a teenaged girl who reported frequently cracking her knuckles daily. In her case, the nodules slowly enlarged over the course of several years, and cracking of the knuckles was listed as the possible cause. Are There Benefits to Cracking Your Knuckles?
When you crack your knuckles, the joints become looser and have more mobility for a short period afterward. This perceived positive feeling may be why some people become habitual knuckle crackers. Another explanation, as reported by one study, is that the movement offers a sort of “therapeutic release.” Chronic knuckle crackers may come to regard the habit as a form of stress relief, although it resembles more of a “nervous habit” like (which it is associated with). Ultimately, there are no significant benefits to cracking your knuckles, and a possibility that it could cause injury or damage to your joints and ligaments over time, so this is one habit that you’re better off without. If you crack your knuckles and find it difficult to stop, I suggest you to try the.
EFT is a powerful self-help method that is very effective for regular stress management as well as for breaking all kinds of addictions, including knuckle cracking. Once the emotional distress is reduced or removed, your body can often rebalance itself and accelerate healing. Specifically, EFT is a form of psychological acupressure, based on the same energy meridians used in traditional acupuncture to treat physical and emotional ailments for over five thousand years, but without the invasiveness of needles. Instead, simple tapping with your fingertips is used to input kinetic energy into specific meridians on your head and chest while you think about your specific problem - whether it is a traumatic event, an addiction, pain, etc. – and voice positive affirmations. This combination of tapping the energy meridians and voicing positive affirmation works to clear the 'short-circuit' — the emotional block — from your body's bioenergy system, thus restoring your mind and body's balance, which is essential for optimal emotional health and the healing of physical disease.

If knuckle cracking is accompanied by pain, swelling, or stiffness, it may be hand osteoarthritis See To find out if knuckle-cracking is harmful, researchers have studied whether crepitus (popping or grinding) of the knuckle joints can raise the risk for hand osteoarthritis. See The results of these studies conclude that—regardless of the frequency or duration of cracking—knuckle crackers' risk for arthritis is no higher than for non-crackers. There's no known connection between knuckle cracking and hand arthritis. The same holds true for any other joint that pops, like the hip or knee. Advertisement Why do knuckles crack? The popping and cracking noises that joints sometimes make is called crepitus. It's caused by gas bubbles in the fluid surrounding your joints (known as ) being released by movement of the joint.
Crepitus is harmless and usually doesn't signal a health problem like arthritis—unless it's accompanied by pain, swelling, or immobility in the joint. See Potential drawbacks of knuckle-cracking However, if you are a habitual knuckle cracker, there still may be reason to rein in your cracking ways.
One study that surveyed 300 patients found that, compared with those who didn't crack their knuckles, the knuckle crackers:. Had more swelling in their hands. Had a weaker grip 1 See The study also found that those who habitually crack their knuckles were also more likely to engage in other nervous habits, like biting their nails. This suggests that you may be able to cut down on your knuckle cracking by following general advice on how to break nervous habits, such as finding a replacement activity or visualizing ahead of time how you will react when temptation strikes. But whether you regularly and intentionally crack your knuckles or just do it occasionally by accident, you don't have to worry that it's raising your risk for arthritis.
The sound of a knuckle being cracked (pictured: common knuckle joints) happens when in humans produce a sharp cracking or popping sound. This occurs during deliberate -cracking, and it is possible to crack many other, such as those in the back and neck, hips, wrists, elbows, shoulders, toes, ankles, knees, jaws, feet, sternum, and the area. The mechanism that produces the cracking sound was until recently unknown. The act of cracking joints means bending a person's joints to produce a distinct cracking or popping sound, often followed by a feeling of satisfaction or relaxation to the person. It is sometimes done as part of a joint adjustment/mobilization routinely performed by a,.
According to traditional belief, the popping of joints, especially knuckles, can lead to and other joint problems. However, medical research has so far failed to conclusively demonstrate a connection between knuckle cracking and long-term joint problems. While the cracking mechanism and the resulting sound is not yet fully understood, it is mainly attributed to nitrogen or carbon dioxide bubbles building up between the joints. Of a cracking finger joint, visualizing cavitation. The physical mechanism that causes the cracking sound as a result of bending, twisting, or compressing joints is uncertain.
Suggested causes include:. Formation of bubbles of as the joint is expanded. within the joint—small cavities of partial vacuum form in the and then rapidly collapse, producing a sharp sound. Rapid stretching of ligaments.
Intra-articular (within-joint) being broken. There were several theories to explain the cracking of joints. Synovial fluid cavitation has some evidence to support it. When a is performed, the applied force separates the articular surfaces of a fully encapsulated synovial joint, which in turn creates a reduction in pressure within the joint cavity. In this low-pressure environment, some of the that are dissolved in the synovial fluid (which are naturally found in all bodily fluids) leave the solution, making a, or, which rapidly collapses upon itself, resulting in a 'clicking' sound.
The contents of the resultant gas bubble are thought to be mainly. The effects of this process will remain for a period of time known as the ',' during which the joint cannot be 're-cracked,' which lasts about twenty minutes, while the gases are slowly reabsorbed into the.
There is some evidence that may be associated with an increased tendency to cavitate. However, recent evidence demonstrates that the cracking sound is produced when the bubble within the joint is formed, not when it collapses. The snapping of tendons or scar tissue over a prominence (as in ) can also generate a loud snapping or popping sound. Cracking of the joints in the foot is sometimes used for massage The common claim that cracking one's knuckles causes is not supported by evidence.
A study published in 2011 examined the hand radiographs of 215 people (aged 50 to 89) and compared the joints of those who regularly cracked their knuckles to those who did not. The study concluded that knuckle-cracking did not cause hand osteoarthritis, no matter how many years or how often a person cracked their knuckles. An earlier study also concluded that there was no increased preponderance of arthritis of the hand of chronic knuckle-crackers; however, habitual knuckle-crackers were more likely to have hand swelling and lowered grip strength. Habitual knuckle-cracking was associated with manual labour, and and was suggested to result in functional hand impairment.
This early study has been criticized for not taking into consideration the possibility of confounding factors, such as whether the ability to crack one's knuckles is associated with impaired hand functioning rather than being a cause of it. Medical doctor Donald Unger cracked the knuckles of his left hand every day for more than sixty years, but did not crack the knuckles of his right hand.

Abstract The relation of habitual knuckle cracking to osteoarthrosis with functional impairment of the hand has long been considered an old wives' tale without experimental support. The mechanical sequelae of knuckle cracking have been shown to produce the rapid release of energy in the form of sudden vibratory energy, much like the forces responsible for the destruction of hydraulic blades and ship propellers.
To investigate the relation of habitual knuckle cracking to hand function 300 consecutive patients aged 45 years or above and without evidence of neuromuscular, inflammatory, or malignant disease were evaluated for the presence of habitual knuckle cracking and hand arthritis/dysfunction. The age and sex distribution of the patients (74 habitual knuckle crackers, 226 non-knuckle crackers) was similar. There was no increased preponderance of arthritis of the hand in either group; however, habitual knuckle crackers were more likely to have hand swelling and lower grip strength. Habitual knuckle cracking was associated with manual labour, biting of the nails, smoking, and drinking alcohol. It is concluded that habitual knuckle cracking results in functional hand impairment.
