Dequerveins tendonitis or tenosynovitis is a condition brought on by irritation or inflammation of the wrist tendons at the base of the thumb. The irritation or inflammation causes the tunnel around the tendon to become enlarge. This makes it painful when you move your wrist.
DeQuervain’s is often thought to be due to over use or repetitive use of the hand. New mothers are especially prone to this type of condition, often over use or holding your hand in a new and awkward position while holding an infant can increase your risk.
Typically patients notice pain over the base of the thumb and the wrist. Pain can radiate down the thumb or up the forearm. With increased pain comes a decrease in range of motion. Some patients may also notice a snapping or popping when moving the thumb.
Treatment can range from a cortisone injection and immobilizing your wrist in a splint for 4 to 6 weeks to medication. In more severe cases surgery is recommended.
