The trapezium is an irregular-shaped carpal bone found within the hand. The trapezium is found within the distal row of carpal bones, and is directly adjacent to the metacarpal bone of the thumb. On its ulnar surface are found the trapezoid and scaphoid bones. [1]: 708
The trapezius [4] is a large paired trapezoid-shaped surface muscle that extends longitudinally from the occipital bone to the lower thoracic vertebrae of the spine and laterally to the spine of the scapula. It moves the scapula and supports the arm. The trapezius has three functional parts: an upper (descending) part which supports the weight ...
The trapezoid bone (lesser multangular bone) is a carpal bone in tetrapods, including humans. It is the smallest bone in the distal row of carpal bones that give structure to the palm of the hand. It is the smallest bone in the distal row of carpal bones that give structure to the palm of the hand.
During trapeziectomy, [30] the trapezium bone is removed without any further surgical adjustments. The trapezium bone is removed through an approximately three centimeter long incision along the lateral side of the thumb. To preserve surrounding structures, the trapezium bone is removed "by splitting" it into pieces.
Within the proximal row, each carpal bone has slight independent mobility. For example, the scaphoid contributes to midcarpal stability by articulating distally with the trapezium and the trapezoid. In contrast, the distal row is more rigid as its transverse arch moves with the metacarpals .

trapezius: Arises from the occipital bone, the ligamentum nuchae, the spinous process of the seventh cervical, and the spinous processes of all the thoracic vertebrae. [3] It attaches to the outer clavicle, the acromion process, and into the spine of the scapula. [3]
