What does crepitation refer to?

Crepitation refers to the noise produced when rubbing bone surfaces together, which can occur in various medical conditions, particularly those involving joint or bone damage, such as osteoarthritis. This sound is typically caused by the rough surfaces of damaged cartilage or bone interacting with one another during movement. Recognizing crepitation is crucial in assessing joint health and diagnosing underlying issues. Understanding this concept is valuable for those studying first aid or related medical fields, as it can aid in effectively evaluating and addressing musculoskeletal injuries.
