The scaphoid is the largest bone in the proximal carpal row. The scaphoid has a convex articular surface proximally for articulation with the radius. The lunate surface is flat. The distal end of the scaphoid consists of two articulating surfaces. The distolateral surface is convex and articulates with the trapezoid and trapezium. The distomedial surface is concave and articulates with the capitate.
