Trapeziectomy
During trapeziectomy, 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.
