Crepitus is associated with gas gangrene, rubbing of bone fragments, air in the superficial tissues, or crackles of a consolidated area of the lungs in pneumonia.2. A clinical sign in medicine characterized by a peculiar crackling, crinkly, or grating feeling or sound under the skin, around the lungs, or in the joints.
Crepitus in soft tissues is often a result of gas, most often air, that has penetrated and infiltrated an area where it should not normally be, as for example the soft tissues beneath the skin (a condition called subcutaneous emphysema).
Crepitus in a joint can represent cartilage wear in the joint space.
The term crepitus is taken directly from the Latin crepitus meaning, "a crackling sound" or "rattle".3. A clicking sound often heard in the movement of the bone joints; for example, in temporomandibular joints (of the lower jaw) resulting from joint irregularities.
2. In poor condition; especially, as a result of being old, overused, or not working efficiently.
3. Etymology: from Middle French decrepit, from Latin decrepitus, from de-, "down" + crepitus, from crepare, "to crack, to break".
2. To roast or to calcine (crystals or salts) until they emit a crackling sound or until the crackling stops.
3. To make a crackling sound when roasted.
