Cracking
Cracking (medicine)
Cracking (/ˈkrækɪŋ/), in the context of medicine, refers to the audible sound or sensation experienced in the joints, often associated with movement or manipulation. The phenomenon is also known as Joint popping or Crepitus.
Etymology
The term "cracking" originates from the English language, where it is used to describe the sharp, snapping sound produced by various actions. In the medical context, it is used to describe the sound produced by the rapid release of gas from within the joint spaces.
Mechanism
The exact mechanism of cracking is not fully understood. However, it is generally believed to be caused by the rapid release of gases, such as Nitrogen, Oxygen, and Carbon dioxide, trapped in the joint spaces. This release of gas occurs when the joint is manipulated or moved, causing a change in pressure within the joint capsule.
