Trigger Finger
Overview
Flexor tendon of the fingers are long tendons which do the complex job of bending multiple joints simultaneously in tandem as well as in isolation. To hold these tendons close to the bone so that they do not bowstring, there is an extensive mechanism of pulleys. These pulleys ensure the smooth movement of the tendon back and forth like a train passing by the train stations.
Why does Triggering of the finger happen?
As the tendon has to pass through the pulley system, occasionally the tendon can become thickened into a nodule and /or the 1st pulley in the palm around the distal crease becomes thicker. This occurs due to repetitive strain. However, it occurs more often in people with diabetes mellitus.
