'''Crepitus''' is "a grating sound or sensation produced by friction between [[bone]] and [[cartilage]] or the [[bone fracture|fractured]] parts of a bone".

Various types of crepitus that can be heard in joint pathologies are:
*Bone crepitus: This can be heard when two fragments of a fracture are moved against each other.
*Joint crepitus: This can be obtained when the affected [[joint]] is passively moved with one hand, while the other hand is placed on the joint to feel the crepitus.
*Crepitus of [[bursitis]]: This is heard when the fluid in the [[Synovial bursa|bursa]] contains small, loose fibrinous particles.
*Crepitus of [[tenosynovitis]]: From [[inflammation]] of the fluid-filled sheath ([[synovium]]) that surrounds a [[tendon]].
