The Triquetrum is a small, triangular bone located in the wrist, specifically in the proximal row of carpal bones. It is situated on the ulnar side, between the lunate and pisiform bones. The Triquetrum plays a crucial role in wrist movement and stability, contributing to the overall function of the hand. This bone is also known as the triquetral bone and is one of eight carpal bones that make up the wrist. It articulates with several other bones, including the scaphoid and hamate, allowing for a wide range of motion in the wrist joint.
