What is upper extremity tenosynovitis?

Upper extremity tenosynovitis is a condition affecting the tendons of an upper extremity (limb). It also affects the lining of the sheath around the tendon (synovium). Tendons are cords of tissue that connect muscles to the bones. With upper extremity tenosynovitis, the sheath and the synovium of the flexor (bending) muscles become inflamed (swollen). The tendons may also become thickened and have a hard time moving through the swollen covering. This may cause pain and tenderness when moving the affected upper and lower arm, hand, wrist, finger, or thumb. This condition usually affects women, athletes, and people of middle age or older. With treatment, such as medicines, a splint, rehabilitation, or surgery, you may be able to resume your normal daily activities.
