Trigger Finger and Trigger Thumb are common causes of hand pain and disability. Enlargement, thickening, or inflammation of the flexor tendon along the distal aspect of the palm, inhibit normal tendon gliding within the tendon sheath, causing the finger to “stick” when flexed and “trigger” when pulled into extension.

And “pop” goes the trigger thumb. One of the most common causes of pain and dysfunction in the hand is trigger thumb.
With trigger thumb, patients present with a painful thumb that sticks or catches, often audibly, upon flexion or extension. Or, the patient’s thumb may be stuck or locked in the flexed position. Trigger thumb is thus named because once the thumb unlocks (often by passive manipulation), it snaps back much like discharging a trigger on a gun.
