What is De Quervain’s Tenosynovitis?
De Quervain's Tenosynovitis is a painful condition affecting the tendons on the thumb side of your wrist. These tendons are responsible for thumb movement, and when they become inflamed or irritated, it can cause discomfort, swelling, and difficulty with hand and wrist function. The condition is most commonly seen in individuals who perform repetitive hand or wrist movements, including athletes, new parents, and those with occupations requiring frequent gripping or lifting.
Causes of De Quervain’s Tenosynovitis:
De Quervain’s Tenosynovitis can develop due to various factors, including:
- Repetitive Hand Movements: Activities that involve gripping, pinching, or twisting the wrist.
- Overuse Injuries: Excessive use of the thumb and wrist, especially during sports or manual labor.
- Pregnancy and Postpartum: Hormonal changes and repetitive lifting of infants.
- Direct Injury: Trauma to the wrist that can lead to scarring and tendon inflammation.
- Inflammatory Conditions: Arthritis or other inflammatory joint diseases.
What are the Symptoms of De Quervain’s Tenosynovitis?
Symptoms typically develop gradually and may include:
- Pain near the base of the thumb, extending to the forearm.
- Swelling and tenderness on the thumb side of the wrist.
- Difficulty moving the thumb and wrist during activities like grasping or pinching.
- A "sticking" or "snapping" sensation during thumb movement.
- Increased pain when making a fist or rotating the wrist.
How is De Quervain’s Tenosynovitis Diagnosed?
Diagnosis is usually made through a physical examination. The Finkelstein test, where the thumb is placed inside a closed fist and the wrist is bent toward the pinky side, is often used to assess pain levels. Imaging tests like X-rays may be recommended to rule out other conditions.
What are the Treatment Options for De Quervain’s Tenosynovitis?
Treatment may include:
- Rest and Immobilization: Wearing a splint to limit movement and reduce inflammation.
- Medications: Anti-inflammatory drugs or corticosteroid injections to relieve pain.
- Physical Therapy: Exercises to strengthen the wrist and improve range of motion.
- Surgery: In severe cases, surgery may be necessary to release the affected tendons.
