#Cracking your knuckles harmful crack#

Second, kids often get attention when they crack their knuckles. Unfortunately, the effect is temporary, which invariably leads to more cracking. That is particularly true for older kids and teenagers who crack the joints in their necks or backs. First, some find that their joints feel a bit looser after theyвЂ™ve been cracked. Kids crack their knuckles for two main reasons. So, does knuckle-cracking cause harm? In most cases, no-unless you count grossed-out friends and parents. The reason you canвЂ™t re-crack your knuckles immediately is because the joint isnвЂ™t вЂњloadedвЂќ until more gas dissolves within the synovial fluid. When the gas bubble bursts, you hear the characteristic popping sound that we all know and some of us love. That vacuum allows more dissolved gas to enter the capsule as a bubble. When a person stretches a joint to crack his knuckles, he creates negative pressure within the capsule. The synovial fluid also contains dissolved gas. Synovial fluid acts as a lubricant for the cartilage and bone. A special type of liquid called synovial fluid is contained within the capsule. The bones that make up a joint are held together by tough, flexible tissue called ligaments. A joint is a place where two bones come together to allow movement. You may also worry that the knuckle-cracker (or should that be knucklehead?) will get arthritis if he repeatedly engages in this behavior.ДЇirst, you need to know a bit about your knuckles, the common name for the joints in your fingers. If youвЂ™re a parent, chances are you get the willies if you see someone cracking his knuckles. If youвЂ™re a kid, chances are you either crack your knuckles or know someone who cracks theirs.
