Trigger Finger — Why Your Finger Gets Stuck
Trigger finger (stenosing tenosynovitis) is a condition where one of your fingers gets stuck in a bent position. It may straighten with a snap — like a trigger being pulled and released. The condition is caused by narrowing of the sheath that surrounds the tendon in the affected finger.
What Causes Trigger Finger?
Repeated gripping: Occupations and hobbies that involve repetitive hand use and prolonged gripping may increase your risk.
Certain health conditions: People who have diabetes or rheumatoid arthritis are at higher risk of developing trigger finger.
Gender and age: Trigger finger is more common in women and in anyone over 40.
Signs and Symptoms
Finger stiffness, particularly in the morning
A popping or clicking sensation as you move your finger
Tenderness or a bump (nodule) in the palm at the base of the affected finger
Finger catching or locking in a bent position, which suddenly pops straight
Treatment Options
Rest and splinting — avoiding activities that require repetitive gripping
Steroid injections — effective in most people, though the problem may recur
Surgery — opens the pulley at the base of the finger so the tendon can move freely
Recovery and Outlook
Most people recover completely with treatment
Steroid injections often show improvement within days to weeks
Surgery typically provides immediate relief with full recovery in weeks to months
Bottom Line
If your finger is catching, locking, or causing pain, don't wait for it to get worse. Early treatment can prevent the need for surgery.
