Crepitus
Pronunciation: KREP-ih-tus
An audible or palpable grating sensation that occurs with joint or tissue movement, often indicating underlying pathology.
Full Definition
Crepitus refers to crackling, grinding, or grating sounds or sensations that occur during movement of joints, tendons, or other tissues. In orthopedic contexts, crepitus can indicate various pathological conditions including osteoarthritis, fracture fragments, or inflamed tissues. The presence and character of crepitus provide important diagnostic information and influence treatment approaches, as certain activities may need modification to avoid exacerbating underlying conditions.
Usage
Usage note: Distinguish from normal joint sounds; pathological crepitus is typically associated with pain or functional limitations.
