The Bones of the Wrist (Ossa Carpalia) 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.

Which is a carpal bone?

Your wrist is made up of eight small bones (carpal bones) plus two long bones in your forearm — the radius and the ulna. The most commonly injured carpal bone is the scaphoid bone, located near the base of your thumb.

Where is the carpal joint located?

It's found on the side of the wrist closest to the palm of the hand. Like the dorsal radiocarpal ligament, it attaches to the radius and both rows of carpal bones. It works to resist extreme extension movements of the wrist.
