De Quervain’s Tendinosis

De Quervain’s tendinosis is a painful condition affecting the tendons on the thumb side of the wrist. It occurs when the tendons that help move the thumb become irritated or inflamed, leading to pain, swelling, and difficulty gripping or pinching. Orthopaedic Associates of Wisconsin’s orthopedic hand specialists provide accurate diagnosis and personalized treatment to relieve discomfort and restore function.

What Causes De Quervain’s Tendinosis?

This condition develops when the tendons in the first dorsal compartment of the wrist—specifically the abductor pollicis longus and extensor pollicis brevis—become inflamed. Common causes and risk factors include:

• Repetitive hand or wrist motions (gripping, lifting, pinching)

• Overuse from work, parenting, or hobbies

• Direct injury to the wrist or tendons

• Arthritis or inflammatory conditions

• Hormonal changes during pregnancy or postpartum

Symptoms of De Quervain’s Tendinosis

• Pain and tenderness near the base of the thumb

• Swelling at the thumb side of the wrist

• Pain that worsens with thumb or wrist movement

• Difficulty gripping or pinching objects

• A “catching” or “sticking” sensation in the thumb

Diagnosis

De Quervain’s tendinosis is typically diagnosed through a physical exam. A common clinical test is the Finkelstein test, where pain is triggered by bending the thumb into the palm and tilting the wrist downward. Imaging studies, such as X-rays or ultrasound, may be used to rule out other conditions.

Treatment Options

At Orthopaedic Associates of Wisconsin, we prioritize non-surgical treatments whenever possible. Options include:

• Rest and activity modification

• Thumb spica splints to reduce motion and inflammation

• Anti-inflammatory medications

• Cortisone injections for targeted relief

• Occupational or hand therapy to improve flexibility and strength

If symptoms persist despite conservative care, surgical release of the tendon sheath may be considered to relieve pressure and allow the tendons to glide smoothly.
