Trigger Finger

  • All flexor tendons of the hand run through a series of pulleys/tunnels to help them glide smoothly and stay in the right place
  • A trigger finger happens when the tendon gets a little benign lump in it, and that leads to the pulley becoming inflamed and tighter
  • Every time the person makes a fist, the tendon lump gets jammed in the pulley, causing the finger to stay bent until it is manually pulled straight
  • There are 3 treatment options for trigger fingers
    • A splint worn at night to hold the finger straight and prevent movement
    • A steroid injection (this fixes the trigger finger in 70%
    • A small surgery to release the pulley/tunnel to allow the tendon to glide freely
