The trapezium bone is a small oblong bone that plays a role in the stability of the carpal tunnel and the thumb joint. Its shape and size, as well as its location below the thumb, cause its integrity to deteriorate over time.
A trapeziectomy is a surgery used to treat thumb arthritis when conservative treatments fail. It involves removing a bone in the wrist, called the trapezium, and replacing it either with a tendon from your own body or a metal or silicone implant.
The trapezium bone (greater multangular bone) is a carpal bone in the hand. It forms the radial border of the carpal tunnel. The trapezium is distinguished by a deep groove on its anterior surface. It is situated at the radial side of the carpus, between the scaphoid and the first metacarpal bone (the metacarpal bone of the thumb).
Trapezium bone arthritis, also known as trapeziometacarpal joint arthritis or thumb base arthritis, is a condition that involves the degeneration of the cartilage within the joint at the base of the thumb where the trapezium bone meets the first metacarpal bone.
The trapezium bone is one of the eight carpal bones of the hand. It is a cube shaped bone located on the radial side of the hand, in the distal carpal row, at the base of the thumb. It articulates with the first metacarpal, second metacarpal, scaphoid and trapezoid bones.
The trapezium is the first and most lateral of the distal row of carpal bones. It forms articulations with the scaphoid, trapezoid, and 1st and 2nd metacarpals. The trapezium bone has a tubercle and groove on its rough palmar surface. These bony features provide a site for tendons and ligaments to either pass through or attach.
