Trigger finger

About trigger finger

Trigger finger, or stenosing tenosynovitis, is a condition in which one of the fingers or the thumb becomes stuck in a bent position and may snap or ‘trigger’ straight suddenly.

This is caused by thickening of the tendon or its sheath, which restricts smooth movement. Trigger finger can interfere with daily activities such as typing, gripping objects, and performing fine motor tasks.
