What is known as crepitus?

Crepitus refers specifically to the sound experienced when bone fragments grind against each other, typically caused by a fracture or dislocation. This sound can also occur in the presence of certain joint disorders where cartilage wears down, leading to more bone-on-bone contact. In a clinical setting, recognizing crepitus is important as it can provide valuable information regarding the status of bones and joints, indicating potential injuries that may require further evaluation or intervention. Understanding this terminology is crucial for EMTs, as it equips them with the language necessary to communicate effectively about patient conditions and to provide appropriate care.
