Trigger Finger and Thumb

Version 3

Trigger finger or trigger thumb is a condition in which one of the fingers gets stuck in a bent position. The medical term for this condition is called stenosing tenosynovitis. The finger may straighten with a snap or stay in the bent position. The cause of trigger finger is inflammation in the protective sheath surrounding the tendon of the affected finger. This inflammation narrows the space thus prohibiting the normal gliding movement of bending fingers. Trigger finger is most often found in people who have work or hobbies that require repetitive gripping movement.

Symptoms of Trigger Finger

The symptoms of trigger finger tend to vary depending on the individual and the degree of affliction (mild to severe). Some symptoms of trigger finger include:

  • Stiffness in finger, especially in the morning
  • Popping or clicking sensation as your finger moves
  • Tenderness at the base of the affected finger
  • Nodule at the base of the affected finger
  • Finger locks in bent position and may suddenly pop straight
  • Permanently locking in a bent position

Symptoms usually are more pronounced in the morning and tend to affect the thumb, third finger and ring finger more than others. Patients may also experience symptoms in more than one finger at a time.

Treatment of Trigger Finger

Once trigger finger has been properly diagnosed, treatment generally includes:

  • Immobilization
  • Anti-inflammatory medication
  • Restricting the activity which caused the injury
  • Corticosteroid injections

Chronic symptoms or recurrent triggering may require surgery.
