What Carpal Bones Does the Ulna Articulate With

The lateral, distal end of the ulna is the head of the ulna. It articulates with the ulnar notch on the radius and with the triangular articular disc in the Wrist Joint.

Do Carpals articulate with the ulna?

The distal end of the ulna thus does not directly articulate with any of the carpal bones. The four distal carpal bones are also held together as a group by ligaments.

What bones do the carpal bones articulate with?

The scaphoid, the lunate and part of the triquetral articulate with the distal end of the radius, to form the radio-carpal joint. The distal surface of the proximal row forms a deeply concave notch, which the bones of the distal row fit into.
