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
