Quizplus · Accepted Answer

A bony eminence at the base of the second or third metacarpal is known as a carpal boss. Carpal bossing is a protrusion of bone that usually occurs at the back of the hand, just above the wrist joint. It can develop over time due to repetitive stress or trauma, or it may be present from birth. It is a different condition than Kirner's deformity or Madelung's deformity, which are both deformities of the wrist joint.
