De-Quervain’s
Tenosynovitis is a painful condition affecting the tendons on the thumb side of
the wrist. If someone has De-Quervain’s Tenosynovitis, it will probably hurt
every time you turn your wrist, grasp anything or make a fist.
Although the
exact cause of de Quervain’s Tenosynovitis isn’t known, any activity that
relies on repetitive hand or wrist movement such as working in the garden,
playing golf or racket sports, typing on a keyboard or lifting your baby, can
make it worse.
Symptoms
of De-Quervain’s Tenosynovitis
Pain near
the base of the thumb: swelling near the base of the thumb, difficulty moving
the thumb and wrist when you’re doing activities that involve grasping or
pinching, a “sticking” or “stop-and-go” sensation in your thumb when trying to
move it.
If the
condition goes too long without treatment, the pain may spread farther into the
thumb, back into the forearm or both. Pinching, grasping and other movement of
the thumb and wrist aggravate the pain.
Causes of
De-Quervain’s Tenosynovitis
Chronic
overuse of the wrist is commonly associated with de Quervain’s Tenosynovitis.
When you grip, grasp, clench, pinch or wrist anything in your hand, you use two
major tendon in your wrist and lower thumb. These tendons normally glide unhampered through the small tunnel
that connects them to the base of the thumb. If you repeat a particular
motion day after day, it may irritate
the sheath around the two tendons, causing thickening that restricts the
movement of the tendons.
Other causes
include direct injury to your wrist or tendon; scar tissue can restrict
movement of the tendons inflammatory arthritis, such as rheumatoid arthritis.
Risk
factors
People
between the ages of 30 and 50 have a higher risk of developing de Quervain’s
Tenosynovitis than those in other age groups. The condition is more common in
women than in men, and it may be associated with pregnancy. Baby care which
involves using your thumbs as leverage to lift your child hundreds of times a
day, may also be associated with the condition.
Jobs or
hobbies that involve repetitive hand and wrist motions may contribute to it as
well.
