Trigger Finger
Trigger finger (stenosing tenosynovitis) is a condition where one of the fingers gets stuck in a bent position and then snaps straight, like a trigger being pulled and released. It occurs when inflammation narrows the space within the tendon sheath surrounding the finger's flexor tendon, making smooth tendon gliding difficult. It can affect any finger and may affect multiple fingers simultaneously.

Symptoms
- Finger stiffness, particularly in the morning
- A popping or clicking sensation with finger movement
- Tenderness or a bump at the base of the finger on the palm side
- Finger catching or locking in a bent position
- Finger stuck in a bent position that you cannot straighten
- Pain when straightening the finger
When to See a Doctor
See a hand specialist if your finger is catching, locking, or you notice a painful nodule at the base of a finger. If the finger becomes locked in a bent position you cannot straighten, seek prompt evaluation.
Treatment Options
Rest and splinting
Resting the affected finger in a splint for 4-6 weeks may resolve mild cases by reducing tendon inflammation.
Corticosteroid injection
Injection into the tendon sheath is highly effective, resolving symptoms in 50-70% of cases. May be repeated once or twice.
Percutaneous release
Office procedure using a needle to release the constricted portion of the tendon sheath. Quick recovery.
Surgical release
Outpatient surgery to open the tendon sheath and allow free tendon movement. Highly effective with rapid recovery.
Recovery Timeline
Corticosteroid injection: improvement within 1-2 weeks. Percutaneous release: return to normal activity in 1-2 weeks. Surgical release: full recovery in 4-6 weeks.
Frequently Asked Questions
What causes trigger finger?
Trigger finger is caused by inflammation and narrowing of the tendon sheath. Risk factors include diabetes, rheumatoid arthritis, repetitive gripping activities, and age (most common in adults 40-60). In many cases, no specific cause is identified.
Can trigger finger go away on its own?
Mild trigger finger may resolve with rest and activity modification. However, most cases require treatment. Corticosteroid injection is the most effective non-surgical treatment. Without treatment, the finger can become permanently locked in a bent position.
What type of doctor treats trigger finger?
Orthopaedic hand surgeons are the specialists for trigger finger. They can perform both the corticosteroid injection and the surgical release procedure.
