One of two element that constitute the basal row of carpals. It articulates with the ulna, radius, radiale, centrale (element Y), and carpal 5(4). This element originates from one condensation center or the fusion of two elements (ulnare and intermedium). Occasionally it may fuse to carpal 5(4), the radiale, or other elements.[AAO]
