Clicking and locking of a finger or thumb is generally known as a “Trigger finger” or “Trigger thumb.” This is a common condition involving inflammation or thickening of the tendon that bends your fingers or thumb. The tendon passes through a pulley in the palm of the hand, however when the tendon is inflamed, it can catch or lock as you make a fist or grip items.
Trigger thumb is common in young children. They likely have had it from birth, but as it is not very noticeable or causing problems, it isn’t picked up until they are a few years old.
Here are a few examples of tendon gliding, blocking and strengthening finger exercises to do at home. If you have any questions or would like to discuss a finger injury, please don’t hesitate to give us a call.
