De Quervain’s Tenosynovitis

De Quervain’s tenosynovitis is an overuse injury affecting two tendons on the thumb side of the wrist. These tendons, the abductor pollicis longus (APL) and extensor pollicis brevis (EPB), can become irritated as they pass through a sheath that protects the connective tissue.

How common is de Quervain’s tenosynovitis?

This condition is relatively common among adults who perform repetitive wrist and thumb movements. It often affects new parents, office workers, tradespeople, and people involved in racquet or grip-based sports. Many cases develop gradually over time rather than from a specific injury.

What causes de Quervain’s tenosynovitis?

This condition is caused by irritation or inflammation of the APL and EPB tendons. Repetitive wrist motions, gripping, lifting, and awkward thumb positioning can increase strain. Hormonal changes and fluid retention may also contribute in some people.

De Quervain’s tenosynovitis risk factors

People are more likely to develop this condition if they engage in repetitive thumb or wrist movement, regularly lift infants, perform manual work, or participate in racquet sports. Ageing, swelling in the wrist, and certain medical conditions may also increase risk.

How is de Quervain’s tenosynovitis diagnosed?

Diagnosis is based on symptoms, medical history, and physical testing. A health professional may perform a movement test to reproduce pain around the thumb side of the wrist. Imaging is rarely required unless symptoms are unclear or another condition is suspected.

What are the de Quervain’s tenosynovitis symptoms?

Symptoms include pain and swelling at, above, or below the thumb side of the wrist. Pain often increases during gripping, lifting, or twisting tasks such as picking up a baby, typing, or lifting a pan. Some people also notice reduced thumb movement or a catching feeling during motion.

How is de Quervain’s tenosynovitis treated?

Treatment focuses on easing irritation and supporting the tendons as they recover. Ice and splinting can help reduce symptoms, while activity modification may ease strain on the wrist. Strength and mobility work with a physiotherapist helps support long-term recovery.

De Quervain’s tenosynovitis exercises

Exercises usually start gently and progress over time. These may include controlled thumb and wrist movements, tendon gliding, and gradual strengthening of forearm and wrist muscles. A physiotherapist can recommend exercises that suit the stage of recovery.
