What is Trigger Finger?

Trigger finger is a condition where one of the fingers or thumb locks or catches in a bent position. It occurs when the tendon sheath that surrounds the flexor tendon becomes inflamed and constricted, making it difficult to straighten the finger.

The exact cause is often unknown, but it is more common in people with certain medical conditions like diabetes, rheumatoid arthritis, and gout. Repetitive gripping activities and prolonged use of vibrating hand tools may also increase chances.

Symptoms include a painful clicking or snapping sensation when bending or straightening the affected finger, stiffness or locking of the finger in a bent position, and the development of a tender bump, or nodule, at the base of the finger.

Diagnosis is based on a physical examination and the characteristic symptoms. We will assess the finger's range of motion, the presence of a nodule, and the severity of locking or catching. Imaging tests are sometimes needed.

Conservative treatment options include rest, activity modification, splinting the affected finger at night to keep it in an extended position, and gentle stretching exercises. Nonsteroidal anti-inflammatory drugs may help reduce pain and inflammation.

Interventional treatment options include injections into the tendon sheath to reduce inflammation and allow smoother gliding of the tendon. If that fails, surgical release of the constricted portion of the tendon sheath may be necessary.

The goal of treatment for trigger finger is to relieve pain, restore smooth finger movement, and prevent the progression of the condition. Early treatment with conservative measures and injections can often resolve symptoms and avoid the need for surgery.
