The fascinating and extremely rare congenital malformation syndrome known as ulnar dimelia, commonly called “mirror hand,” defies our usual understanding of human anatomy. This disorder is characterized by the duplication of structures on the ulnar side of the hand, resulting in a hand with two sets of fingers arranged symmetrically, as if one were a mirror image of the other. Unlike a typical hand, where each finger has separate functions and tendons, in cubital dimelia the tendons and muscles may be connected to one another, so that the movement of one finger is accompanied by a “mirror” movement in its counterpart. One of the most notable characteristics is the absence of a normal thumb, which alters typical grasping ability, and the presence of multiple fingers that, although they appear duplicated, often share bone and tendon structures. This pattern differs from simple polydactyly (having extra fingers), since here the duplication forms bilateral symmetry within the same hand. Ulnar dimelia is so rare that very few cases have been reported in the medical literature. Surprising.
