De Quervain tenosynovitis is a painful irritation of the tendons that run from the wrist to the thumb. These tendons pass through a tunnel-like tissue at the wrist. It can put more pressure on the tendons and make them hard to move.
The exact cause it not known. It may be due to injury, such as repetitive motion or a direct blow to the area.
This problem is more common in women who are over 40 years of age. It is also more common during pregnancy and after childbirth.
Some activities may raise your risk, such as:
Sports, such as cross-country skiing
Repeatedly lifting a baby, young child, or pet
Certain jobs, such as those that involve using a hammer or similar tool
Problems may be:
Pain at the base of the thumb and sometimes along the forearm
Pain when using the hand and thumb, such as when grabbing or twisting items
Swelling or a fluid-filled cyst over the thumb side of the wrist
A snapping or catching feeling when moving the thumb
The doctor will ask about your symptoms and health history. A physical exam will be done. It will focus on your hand and arm. You will be asked to move your fingers and wrists. This is all that is needed for diagnosis.
The goal of treatment is to ease pain and promote movement. This may be done with:
A splint to help rest the area
Medicine to ease pain and swelling
Physical therapy and occupational therapy to improve function
Surgery may be done if other methods do not help. The surgery will open the tunnel so the tendons can move freely.
There are no guidelines to lower the risk of this problem.
