Question: A question on Knuckle Cracking for Doctors, Med students, and Nurses.?
Okay so I crack my knuckles sometimes, Yes I know it's bad. I have always wondered is it really my Knuckle I am cracking.? And why is it possible to crack a bone.?.?.? also if you crack your knuckles you will notice that after you crack all of them like 20-30 minutes later you can crack some of them again, but not all. I'm pretty confused on that.
Thanks for answering!
also I can crack my pinky finger on my right hand as many times as I want and It never stops. Does that mean I broke it at one point.?

Answers:
Besides being a poor practice in social etiquette (you really should never crack your knuckles in front of other people) the health effects of cracking knuckles have been over stated.

To deliberately produce the clicking sounds, many people bend their fingers into unusual positions. These positions are usually ones that their own muscles are unable to achieve, and which are not commonly experienced in everyday use. For example, bending a finger backwards away from the palm (into extension), pulling them away from the hand (distraction), compressing a finger knuckle toward the palm (into flexion), or twisting a finger about (torsion).

The snapping of tendons or scar tissue over a prominence (as in snapping hip syndrome) can also generate a loud snapping or popping sound.

The physical mechanism is as yet unproven, but suggested theories include:

1. Cavitation within the joint
