Trigger finger can be a very painful condition that limits the movement of the affected finger. The phrase “trigger finger” comes from the quick snapping or sudden popping of the finger when it unlocks from a bent position, similar to releasing a gun trigger. Patients usually have complaints of soreness at the base of the affected finger. This is then followed by catching or locking of the finger, which usually gets worse with time. On occasion, straightening the trigger finger my require assistance from the other hand.
What causes trigger finger?
Trigger finger usually happens when a tenosynovium, a protective coat on a tendon, is inflamed causing the tendon to become stuck and unable to move freely inside the tenosynovium. The inflammation of the tenosynovium can cause the space between the tendon sheath to narrow and become restricted. When the tendon struggles to slide through the sheath, the finger may experience the trigger sensation.
Health conditions like arthritis and diabetes may cause trigger finger, as well as repeated use of the finger or hand. Occupations or hobbies that require constant use of the fingers, like a guitarist, may also be affected by trigger finger due to repeated use and strain on the fingers for long periods of time.
Symptoms of Trigger Finger
The most common symptom of trigger finger is the locking and snapping of the finger, but here are some additional symptoms:
- Snapping sensation as you attempt to straighten your finger
- Grasping objects may cause the finger to lock
- Finger stiffness in the morning

Treating Trigger Finger
Treatment of trigger finger depends on the severity of the injury. Minor cases may only require rest, ice and anti-inflammatory medications. However, moderate cases may require splinting and physical therapy, and in severe cases surgery may be required.
In severe cases doctors may also recommend a procedure called percutaneous trigger finger release, which is when doctors use a needle to release the locked finger.
