What is Trigger Finger?
Trigger finger is a condition that causes one of your fingers to remain stuck in a bent position. Another term for trigger finger is stenosing tenosynovitis (stuh-NO-sing ten-o-sin-o-VIE-tis). Your finger might straighten out with a snap, like a trigger being pulled and released (MayoClinic.org).
What Causes Trigger Finger?
Inflammation will cause a narrowing of the space within the sheath surrounding the tendon in the afflicted finger. If severe, this finger can remain locked in a bent position.
Who is at Risk?
Women, those with diabetes or rheumatoid arthritis, and those working in jobs with repetitive gripping actions are at highest risk for developing trigger finger.
