The cracking mechanism and the resulting sound is caused by carbon dioxide cavitation bubbles
Interphalangeal joints of the hand suggests the presence of osteoarthritis or psoriatic arthritis. Interphalangeal joints of the hand The interphalangeal joints of the hand are the hinge joints between the phalanges of the fingers that provide flexion towards the palm of the hand. There are two sets in each finger (except in the thumb, which has only one joint): Anatomically, the proximal and distal interphalangeal joints are very similar. There are some minor differences in how the palmar plates are attached proximally and in the segmentation of the flexor tendon sheath, but the major differences are the smaller dimension and reduced mobility of the distal
