Trigger Finger

Trigger finger is a painful or painless clicking, snapping or locking of a finger. In the beginning, finger movement is uneven. Untreated, this progresses to snapping of the finger as one makes a fist. With time, the finger gets unexpectedly locked when one tries to hold an object. Finally, the finger locks in bent position as the tendon gets locked outside the flexor tendon sheath, or the sleeve. Rarely, the patient cannot make a full fist, as tendon becomes locked inside the sleeve of the tendon. It is painful to unsnap and straighten the finger. Finally, the finger becomes locked in the bent position and cannot be unlocked. Trigger finger may occur in one or more fingers at the same time, or may occur in different fingers at different times.
