Isolated absence of human carpal bones.
An unusual instance of congenital isolated absence of carpal bones, in a 38-year-old woman, characterized by total lack of the scaphoid, lunate, and pyramidal and a massive fusion of the distal carpal row is reported. This condition is thought to have been the result of an embryonic error exclusively involving the portion of the autopodic blastema from which the carpus originates.
