What causes trigger fingers?
Trigger finger generally results from inflammation within a tendon sheath, restricting tendon motion. A bump (nodule) in the tendon also may form. Tendons are fibrous cords that attach muscle to bone. Each tendon is surrounded by a protective sheath.
Where is the flexor tendon sheath?
The muscles that move the fingers and thumb are located in the forearm and hand. Long tendons run from the end of the muscles through small tunnels in the wrist and hand to attach to the small bones (phalanges) of the fingers and thumb. These tunnels are called tendon sheaths.
