At the base of the wrist, we have eight carpal bones anatomically arranged in two rows. The proximal row includes scaphoid, lunate, triquetrum, and pisiform bones, but the distal row — the hamate, capitate, trapezium, and trapezoid bones. The arrangement of carpal bones in two rows poorly correlates with the wrist's kinesiology* but is universally accepted as the main anatomical classification.
