De Quervain Tenosynovitis

De Quervain tenosynovitis is most commonly caused by repetitive use of the hand and wrist, especially movements that involve gripping, pinching, or wringing. Activities such as lifting a child, gardening, texting, or using tools can strain the tendons over time. When these movements are repeated frequently, the tendon sheath can become irritated, leading to swelling and restricted motion.

Certain groups of people are more likely to develop this condition. It is more common in adults between the ages of 30 and 50. Women are affected more often than men, and new parents, especially mothers, are at higher risk due to frequent lifting of infants. This is sometimes referred to as “mommy thumb.” Jobs or hobbies that involve repetitive wrist and thumb motions, such as typing, knitting, or manual labor, can also increase risk.

Other contributing factors may include direct injury to the wrist, which can cause scar tissue that restricts tendon movement, or inflammatory conditions such as arthritis. In some cases, fluid retention during pregnancy or hormonal changes may also play a role in increasing pressure within the tendon sheath.

The most common symptom of De Quervain tenosynovitis is pain along the thumb side of the wrist. This pain may develop gradually or appear suddenly, and it often worsens with thumb or wrist movement. Activities like turning a doorknob, opening a jar, or lifting objects can trigger or intensify the discomfort.

Many people also notice swelling near the base of the thumb. The area may feel tender to the touch, and in some cases, a small lump or thickening can be felt over the tendon sheath. Movement of the thumb may feel stiff or restricted, and some individuals experience a catching or snapping sensation when trying to move the thumb.

Pain may extend from the wrist up into the forearm or down into the thumb. As the condition progresses, grip strength may decrease, making it harder to hold or carry items. Without treatment, symptoms can worsen and begin to interfere with daily activities and quality of life.

De Quervain tenosynovitis is usually diagnosed through a physical exam and a review of symptoms. Your Acceleration Orthopedics healthcare provider will ask about your medical history, daily activities, and when the pain began. They will examine the wrist and thumb for tenderness, swelling, and range of motion.

One common test used to confirm the diagnosis is called the Finkelstein test. During this test, you make a fist with your thumb tucked inside your fingers, then gently bend your wrist toward your little finger. If this movement causes sharp pain along the thumb side of the wrist, it is considered a positive sign of De Quervain tenosynovitis.

Imaging tests such as X-rays are not usually needed to diagnose this condition, but they may be used to rule out other causes of wrist pain, such as fractures or arthritis. In rare cases, ultrasound or other imaging studies may be used to get a closer look at the tendons and surrounding tissues.

Early diagnosis is important because it allows for more effective treatment and can help prevent the condition from worsening. If you are experiencing ongoing wrist or thumb pain, especially with repetitive activities, it is important to seek evaluation. With proper care, most people experience significant relief and are able to return to normal activities without long-term problems.
