Pediatric trigger thumb (PTT) is also called a flexion contracture of the IP joint ). It is a condition that affects the movement of the thumb in children. The thumb gets stuck in a bent (flexed) position. A contracture means that the thumb can no longer stretch or straighten.
Tendons work to make our thumbs move. They are like strings inside your thumb and are held in place by a tunnel system of ligaments (also known as “pulleys”). These tunnels or ligaments keep the tendon next to the bone and allow it to slide back and forth
