Rolling With It

Gamer's Thumb involves the inflammation of the fluid-filled sheath or tunnel (called the synovium) that surrounds the two tendons that control movement of the thumb. You may hear it referred to as flexor tenosynovitis, stenosing tenosynovitis, de Quervain's tenosynovitis (dih-kwer-VAINS ten-oh-sine-oh-VIE-tis), or de Quervain syndrome.

Two common stenosing tenosyonvitis diagnoses are:

• DeQuervain's Syndrome - this involves the first dorsal compartment of the wrist
• Trigger finger - this occurs when a fibrous nodule develops in the digital flexor tendon

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.
