[trəpē′zē·əm] pl. trapezia, trapeziums
Etymology: Gk, trapezion, small table
a carpal bone in the distal row of carpal bones. The trapezium articulates with the scaphoid proximally, the first metacarpal distally, and the trapezoideum and the second metacarpal medially. Also called greater multangular, os trapezium.
