sound heard, and the sensation felt when two rough surfaces rub together. Crepitus may be experienced when the ends of a broken bone rub
against each other, or in osteoarthritis
when the cartilage
that covers the bony surfaces of a joint
and the roughened areas of the joint grind
against each other.The sound is usually loud enough to be heard by the naked ear. Fainter sounds, audible through a stethoscope
, are produced in the lung
as a result of inflammation
-due to pneumonia
, for example.
The term "crepitus" is also used to describe the sounds made when an area of air under the skin (see Emphysema, surgical) or gas gangrene (gas infected tissue) is pressed.
