Overview
Trigger finger occurs when a flexor tendon in the hand no longer glides smoothly through its sheath, causing the finger to catch, click, or lock as it bends. It is common, more frequent in people with diabetes, and often affects the thumb or ring finger.
Common Symptoms
- Catching, clicking, or locking of a finger
- A tender bump at the base of the finger in the palm
- Stiffness, especially in the morning
- A finger that locks bent and must be straightened by hand
Causes & Risk Factors
- Repetitive gripping
- Diabetes and inflammatory conditions
- More common in women and in middle age
Treatment Options
- Splinting and activity modification
- Anti-inflammatory measures
- Corticosteroid injection
- A short release procedure for persistent locking
Recovery & What to Expect
Many cases resolve with splinting and injection. When release is required, it is a brief outpatient procedure that relieves the catching immediately, with a quick return to activity.
