Thickening of pulley
In the finger, pulleys are the series of rings that create a tunnel from which the tendons must glide. These pulleys are responsible for holding the tendons close against the bone. There is fluid lining present with tendons and the tunnel that helps easy gliding of the tendon through the pulley. Trigger finger can also arise when the pulley present at the base of the finger becomes too thick. When the puller thickness it tightens around the tendons which makes it very difficult for the tendon to move freely through the pulley. This increase in resistance to the smooth gliding of the tendon causes pain and popping sensation in the finger or the thumb.
