The scaphoid is one of the eight carpal bones of the hand. It is classified as a short bone and in the anatomical position, it is the lateral most of the carpal bones in the proximal row. Together with the lunate and triquetrum, its proximal surface articulates with the distal end of the radius to form the radiocarpal (wrist) joint.
It has a prominent tubercle on its lateral palmar surface which serves as an attachment point for the abductor pollicis brevis and the flexor retinaculum. It forms part of the lateral aspect of the carpal arch as well as part of the floor of the anatomical snuffbox. The radial collateral ligament is also attached to its lateral surface.
English: Scaphoid bone
Latin: Os scaphoideum
|Function||Forms part of the wrist joint, carpal arch and anatomical snuffbox. Attachment site for adductor pollicis brevis and flexor retinaculum.|
