De Quervain’s tendonitis is a painful condition affecting the tendons on the thumb side of the wrist. If you have noticed a sharp pain when turning your wrist, gripping objects, or making a fist, this condition may be the cause. It is particularly common among people who perform repetitive hand and wrist motions — and for Boise and Treasure Valley residents who work in trades, spend long hours at a computer, or stay active with outdoor recreation, it can develop without much warning.

Understanding what drives the condition, recognizing symptoms early, and knowing your treatment options can help you get back to comfortable hand function without unnecessary delay.

What Is De Quervain’s Tendonitis?

De Quervain’s tendonitis — sometimes called De Quervain’s tenosynovitis — involves inflammation of the tendons and their surrounding sheaths on the thumb side of the wrist. Two tendons that control thumb movement pass through a tunnel-like structure called a tendon sheath at the base of the thumb. When the tendons or the sheath become inflamed or thickened, the tendons cannot glide smoothly, resulting in pain and restricted movement.

The condition is named after the Swiss surgeon Fritz de Quervain, who first described it in 1895. According to the American Academy of Orthopaedic Surgeons, De Quervain’s tendonitis is one of the most common causes of wrist pain and tends to affect women more frequently than men, particularly between the ages of 30 and 50.

Common Causes and Risk Factors

Repetitive hand and wrist motions are the primary driver of De Quervain’s tendonitis. Activities that involve gripping, wringing, pinching, or twisting the wrist place repeated stress on the thumb tendons and their sheaths. Over time, this stress produces irritation and swelling that narrows the tendon compartment.

Specific risk factors include:

  • Repetitive occupational tasks — jobs that involve frequent hand tool use, assembly work, or prolonged keyboard and mouse use
  • Recreational activities — gardening, fishing, golf, racquet sports, and other hobbies common among Treasure Valley residents
  • New parents — repeatedly lifting and holding an infant with the thumbs extended is a well-recognized trigger, earning the condition the informal name “mommy’s wrist”
  • Inflammatory conditions — rheumatoid arthritis and other inflammatory disorders can increase susceptibility
  • Direct injury — a blow or fall affecting the thumb side of the wrist can initiate the inflammatory process

The condition can also develop during pregnancy and in the postpartum period due to hormonal changes and fluid retention that contribute to tendon swelling.

Recognizing the Symptoms

De Quervain’s tendonitis produces several characteristic symptoms that typically develop gradually:

Pain and tenderness along the thumb side of the wrist is the most prominent symptom. The discomfort often worsens with thumb and wrist movement — particularly when grasping objects, turning the wrist, or making a fist. Some patients notice swelling at the base of the thumb and a catching or snapping sensation when moving the thumb.

A simple self-assessment known as the Finkelstein test can help identify the condition. To perform it, make a fist with your thumb tucked inside your fingers, then gently bend your wrist toward your little finger. If this motion produces sharp pain along the thumb side of the wrist, De Quervain’s tendonitis is a strong possibility.

If you are experiencing these symptoms and they are not improving with rest, scheduling an evaluation with Idaho Shoulder to Hand can help confirm the diagnosis and determine the most appropriate treatment path.

Non-Surgical Treatment Options

Most cases of De Quervain’s tendonitis respond well to conservative treatment, particularly when the condition is addressed early.

Rest and activity modification. Reducing or temporarily avoiding activities that aggravate the condition is an important first step. This does not mean complete immobilization — rather, it means identifying and modifying the specific motions that are contributing to irritation.

Splinting. A thumb spica splint that immobilizes the thumb and wrist can significantly reduce stress on the affected tendons. Wearing a splint consistently — especially during activities and at night — allows the tendons to rest and inflammation to subside.

Anti-inflammatory medications. Over-the-counter nonsteroidal anti-inflammatory drugs such as ibuprofen or naproxen can help manage pain and reduce inflammation during the acute phase.

Corticosteroid injections. For moderate to severe symptoms, a corticosteroid injection into the tendon sheath is often highly effective. Research suggests that a single injection resolves symptoms in approximately 80 percent of patients. The injection delivers targeted anti-inflammatory medication directly to the source of the problem.

When Surgery May Be Recommended

If symptoms persist despite several months of conservative treatment, surgical release may be recommended. The procedure involves opening the tendon sheath to create more space for the tendons to glide freely. It is typically performed on an outpatient basis and involves a small incision on the thumb side of the wrist.

Recovery after De Quervain’s release surgery generally progresses well. Most patients experience significant pain relief within a few days of the procedure and can begin gentle range-of-motion exercises shortly after. Full recovery, including return to demanding hand activities, typically occurs within four to six weeks. Physical or occupational therapy may be recommended to restore strength and flexibility.

Preventing Recurrence

Once symptoms have resolved, taking steps to reduce the risk of recurrence is worthwhile:

  • Pay attention to ergonomics — adjust your workstation, tools, and technique to minimize repetitive wrist strain
  • Take regular breaks during activities that involve sustained gripping or pinching
  • Strengthen the muscles of the hand, wrist, and forearm through targeted exercises
  • Use proper technique when lifting — particularly when holding infants or young children
  • Address early symptoms promptly rather than pushing through increasing pain

For Treasure Valley residents whose work or hobbies involve significant hand use, awareness of early symptoms and timely intervention can prevent a manageable condition from becoming a prolonged problem.

Getting the Right Evaluation

Wrist and thumb pain can result from several different conditions, including other forms of tendonitis, arthritis at the base of the thumb, and ligament injuries. An accurate diagnosis is important because treatment differs across these conditions. At Idaho Shoulder to Hand, we specialize in upper extremity evaluation and treatment — from the shoulder down to the fingertips. If wrist or thumb pain is interfering with your daily activities, our Boise team can help you identify the cause and build a treatment plan that fits your needs.
