The trapezoid bone is one of the eight small bones that make up the wrist, known as the carpal bones. It is located in the distal row, situated between the capitate bone and the trapezium bone. The trapezoid is shaped like a trapezoid, which is where it gets its name, and it plays a crucial role in the movement and stability of the wrist. This bone articulates with the second metacarpal, contributing to the base of the index finger. The trapezoid bone helps facilitate various hand movements, allowing for dexterity and grip. Its position and connections are essential for the overall function of the hand and wrist.
