The palm of the hand contains a fibrous layer of tissue called the palmar fascia. You may have to straighten the bent finger with your other hand. In the case of trigger finger, the affected finger may stay curled or may suddenly pop out straight. You may be asked to make a fist and then straighten your fingers. Diagnosis is typically made by physical examination by the physician. Because of this, when you try to straighten the finger, the tendon catches and can “trigger” into a bent position as it tries to squeeze back through the sheath. In the case of trigger finger, one of these tendons becomes inflamed and the tendon or the sheath surrounding it can swell and thicken to the point that the tendon can no longer glide smoothly. Synovium produces a fluid that allows the tendon to glide easily as you bend and straighten your finger. Each of these tendons is surrounded by a sheath which is lined with synovium. On the palmar side of each finger, there is a tendon that helps each finger bend toward the palm. Trigger finger and Dupuytren’s contracture are both problems that affect the fingers and so one issue is often confused for the other.
