Bony bumps on the finger joint closest to the fingernail are called Heberden's
nodes. Bony bumps on the middle joint of the finger are known as Bouchard's
Bony bumps are also common at the base of the thumb. These
bumps do not have a nickname, but the joint is called the CMC or
carpometacarpal joint. The name comes from the bone of the wrist (carpal) and
the bone of the thumb (metacarpal).
