Trigger Finger And Trigger Thumb
 
     
When the flexor tendon and its sheath in a finger or thumb thicken or begins to swell, you may have a condition called Trigger finger or trigger thumb. Normal, smooth gliding is prevented when this thickening pinches the tendon. When too much swelling occurs, the tendon gets stuck and locks or clicks. Occasionally, this can occur from a laceration of the flexor tendon.

Symptoms of trigger finger and trigger thumb include:
  • When the thumb is bent or straightened a snap or click may be heard.
  • The finger or thumb may not have full range of motion or be completely stuck in one position.
  • Tenderness may occur in the palm and occasionally pain over the affected finger or thumb will occur that increases with movement.
  • You may have a tender bump (nodule) in the palm near the affected finger or thumb. The bump may appear to move when you bend or straighten the finger or thumb.


    • Trigger finger and trigger thumb are more common in people who have diabetes, rheumatoid arthritis, or a history of repeated injury to the area, although the exact reason for this is not known. Primary treatment for trigger finger or trigger thumb includes rest (immobilization), anti-inflammatory medication, and often this condition is helped with a shot of cortisone. Splinting the effected digit for an extended period is often as effective as shots or surgery. If these treatments don't help, surgical intervention may be required.
