Can Cracking Knuckles Cause Arthritis? Discover the Cause of the Pop
New Delhi: The habit of cracking knuckles has long been a subject of debate, with concerns raised about its potential negative impact on bone health. Many individuals engage in this habit frequently, while others believe it can lead to bone-related ailments. The prevailing notion is that habitual knuckle-crackers may be at risk of developing arthritis due to the popping sound that accompanies the act, which is believed to deplete lubrication in finger joints.
Understanding the Mechanism of Knuckle Cracking
Experts have shed light on the mechanism behind the sound produced when knuckles are cracked. According to research conducted by John Hopkins University, the sound is a result of bubbles bursting in the synovial fluid, which serves to lubricate and facilitate movement within joints. The synovial fluid contains a significant amount of dissolved gases, and when knuckles are cracked, the stretching of the joint's capsule reduces the pressure inside. As a consequence, the vacuum created is filled by the gas that was previously dissolved in the synovial fluid, leading to the bursting of a bubble and the characteristic cracking sound. It should be noted that the gases take some time to re-dissolve in the synovial fluid, which explains why knuckles cannot be immediately "re-cracked."
Dispelling the Arthritis Myth
The belief that cracking knuckles can cause arthritis has persisted among many individuals, as they argue that it improves joint mobility and therefore continue the habit. However, numerous research studies have debunked the association between knuckle cracking and the development of arthritis.
A study published in the Journal of the American Board of Family Medicine examined 215 participants with arthritis, of whom 20 per cent regularly cracked their knuckles. The results indicated that 18.1 percent of the knuckle-cracking participants developed arthritis in their hands, compared to 21.5 per cent of those who did not crack their knuckles. This finding led the researchers to conclude that the risk of developing arthritis is roughly the same, regardless of whether an individual cracks their knuckles or not.
Treatment and Recommendations
Medical professionals generally believe that cracking knuckles or joints are not inherently linked to any significant health issues and thus should not cause undue concern. However, if pain and swelling are experienced in the affected area, it is advisable to seek medical attention.
The American Association of Orthopedic Surgeons suggests that knuckle cracking can be a consequence of joint instability or looseness in the elbow, or possibly a tear in the protective cartilage. To alleviate the habit, experts recommend keeping the hands busy with alternative activities. Using stress balls, fidgeting toys, engaging in drawing or doodling, or finding other ways to occupy the hands can be effective strategies for reducing the urge to crack knuckles.
In conclusion, while cracking knuckles may be seen as a bad habit by some, the notion that it causes arthritis lacks scientific evidence. Individuals who crack their knuckles can take solace in the research findings that show no significant correlation between the practice and the development of arthritis. However, if discomfort or swelling arises, it is advisable to consult a healthcare professional for a thorough evaluation and appropriate guidance.
