Trigger Finger

These tendons travel in a narrow tunnel and when swelling occurs, they become too large to glide properly in the tunnel. Over time the tendon may develop a nodule and the finger starts to lock. This is commonly seen in women, in diabetics or with repetitive use of the hand.

Soreness and stiffness mainly followed by locking of the finger in a bent position.

The diagnosis is based on the clinical history and examination. Popping is typical. Over time, the finger can become permanently stiff.

Splinting, NSAIDS and rest can be efficient. Sometimes a cortisone injection can be performed.

Endoscopic release of the pulley system causing the locking can be done in minutes under local anesthesia in most cases. The use of hand is unrestricted after a couple of days. Therapy is sometimes required. Results may vary.
