Everything To Know About De Quervain Syndrome

What is De
Quervain Syndrome?

De Quervain syndrome, also known as de Quervain tenosynovitis, is a painful condition affecting the tendons on the thumb side of the wrist. Tendons are the rope-like structures that the muscle uses to pull the bone. You can see them on the back of your hand when you straighten your fingers. Chronic overuse, such as repeating a particular hand motion day after day, may irritate the covering around the tendons. If the covering becomes irritated, the tendons can thicken and swell, leading to pain and swelling on the thumb side of the wrist.

Signs & Symptoms Of
De Quervain Syndrome

  • Pain and swelling on the thumb side of the wrist.
  • Limited movement and difficulty gripping or pinching.
  • A “sticking” or “stop-and-go” sensation in the thumb when moving it.

    If left untreated, the pain may spread into the thumb or forearm, and moving the thumb and wrist can exacerbate the discomfort.

Causes of De
Quervain Syndrome​

The exact cause of de Quervain’s Tenosynovitis is uncertain, but changes in hand usage may play a role. Contributing factors likely include repetitive motions, hormonal fluctuations, and swelling. In new mothers, this condition usually manifests about 4 to 6 weeks postpartum.

Diagnosis of De
Quervain Syndrome​

Diagnosing de Quervain syndrome typically involves a combination of medical history, physical examination, and specific tests. At Seattle Hand Surgery Group, one of our hand surgeons will begin by inquiring about your symptoms, including the location of pain and any activities that exacerbate discomfort. First, during a physical examination, your hand surgeon will assess for tenderness, swelling, and range of motion in the wrist and thumb. One specific test used is the Finkelstein Test, which involves bending your thumb across the palm of your hand, curling your fingers down over the thumb, and then bending your wrist toward your little finger. If this movement elicits pain on the thumb side of your wrist, it likely indicates de Quervain syndrome. Imaging tests are generally not necessary for diagnosis.

Treatment of De
Quervain Syndrome

Treatment for de Quervain syndrome focuses on reducing inflammation, preserving thumb movement, and preventing recurrence. Early intervention can lead to improvement within 4 to 6 weeks, and if the condition occurs during pregnancy, symptoms typically resolve by the end of pregnancy or breastfeeding.

Medications play a key role in management; over-the-counter pain relievers such as ibuprofen (Advil, Motrin IB) and naproxen sodium (Aleve) can effectively alleviate pain and swelling. In some cases, corticosteroid injections may be recommended to address inflammation, often resulting in recovery after just one injection if treatment occurs within six months.

Initial therapy often involves immobilizing the thumb and wrist with a splint, avoiding repetitive movements, and applying ice. Physical or occupational therapy can also provide exercises to strengthen the wrist and reduce irritation. For severe cases, surgery may be necessary to relieve pressure on the tendons, followed by rehabilitation to prevent future issues.

De Quervain Syndrome FAQ

Is De Quervain’s Syndrome the same as carpal tunnel?
No, de Quervain’s syndrome and carpal tunnel syndrome are different conditions. De Quervain’s primarily affects the tendons on the thumb side of the wrist, while carpal tunnel syndrome involves compression of the median nerve in the wrist, leading to different symptoms and treatment approaches.

Which tests are used to detect De Quervain’s Syndrome?
The primary test for de Quervain’s syndrome is the Finkelstein test, which assesses pain when bending the thumb across the palm and tilting the wrist. A physical examination may also be conducted to check for tenderness and swelling, while imaging may be necessary to visualize tendon inflammation if needed.
