Jaw Cracking Habit

Recognize this sound? if you pop or crack your joints, you probably do. what happens to our joints when we crack them? And is it bad for you? Synovial fluid is this lubricantlike substance that’s found in between your joints. It kind of looks like an egg yolk. So when you stretch out your joint, you are releasing gas, and that gas forms a bubble and it collapses and pops. In order to crack the same knuckle again, you have to wait about 20 minutes for the gas to return back to that fluid. So how is that different from a pop you hear when.

You stand up quickly? the sound you’re probably hearing then is the snapping sound tendons make when slide between muscles or over bones. When a joint moves, the tendon snaps quickly over and it makes a popping sound. So is the knuckle cracking habit safe? Probably. Donald Unger was sort of a selfdescribed researcher who chose to pop the joints in one of his hands for 60 years, but not the other one. And he wanted to find out if popping your knuckles would actually give you arthritis. After 60 years of doing it, he found that.

Does Cracking Your Knuckles Cause Arthritis

Have you ever cracked your knuckles and had someone yell at you to stop because it causes arthritis? 2554% of the worlds population cracks their knuckles, men more so than women. Does this mean up to 54% of us will get arthritis? The short answer is no. There are different types of arthritis and no study has ever shown a link between cracking your knuckles and it causing any type of arthritis. Lets talk about why and what is actually causing the cracking noise when you crack youre knuckles.

The knuckles are the joints formed by the bones in our fingers. each finger consists of three bones (phalanges). Theyre named based on where they are in relation to the palm of your hand. Theres the proximal phalange (closest to the palm), the middle phalange, and the distal phalange (farthest from the palm). The first knuckle is called the metacarpophalangeal joint (MCP). (Say that after drinking 3 beers and watch the laughter ensue!) The second knuckle is the proximal interphalangeal joint (PIP) and.

The last knuckle is the distal interphalangeal joint (dip). the fingers, and thus the joints, are held in place by ligaments and tendons. There are no muscles in the fingers and movement is controlled by forearm muscles pulling on your finger tendons. Your knuckles are also covered by a joint capsule known as your synovial capsule. Theres fluid within this capsule known as synovial fluid. This fluid provides the lubrication and nutrients needed for the joint and surrounding bone. This fluid also contains several gases.

(oxygen, nitrogen and carbon dioxide). when you crack your knuckles, you stretch out the synovial capsule creating a negative pressure within the joint. This pulls the gasses out of the fluid in the form of a bubble which bursts to create the popping sound. To crack the same knuckle again, you have to wait for more gases to build up in the synovial fluid. There are over 100 different types of arthritis. Generically, arthritis is simply inflammation of your joints. It can be caused by everything from autoimmune problems (rheumatoid arthritis),.

Bacterial infections (nongonococcal bacterial arthritis), to sexually transmitted diseases (gonococcal arthritis). In the case of cracking knuckles, the type of arthritis often thought to be caused by it is the most common, osteoarthritis. Osteoarthritis can be a normal result of the aging process. It can also be caused by excessive wear and tear on the joint. The result is cartilage breaking down and wearing away. The bones can begin to rub together and sometimes cause spurs to develop. Pain, swelling, and.

Stiffness are the most common symptoms. So does the constant popping of the gases within the synovial fluid cause the excessive wear and tear that can cause osteoarthritis? There have been several studies that looked at this question, and none have shown that habitual knuckle cracking causes wear and tear. One study looked at 300 patients over 45 years old and found that among the worst knuckle crackers there was no increase in the incidence of arthritis. They did find,.
