De Quervain's Tenosynovitis is an overuse injury involving inflammation and irritation of the tendons that control thumb movement as they pass through a narrow tunnel (first dorsal compartment) on the thumb side of the wrist.

The two tendons most commonly affected are:

• Abductor Pollicis Longus (APL)
• Extensor Pollicis Brevis (EPB)

When these tendons become inflamed or their surrounding sheath thickens, movement through the tendon tunnel becomes restricted, causing pain and discomfort.

The condition is common among:

• New parents lifting infants repeatedly
• Individuals performing repetitive hand and wrist movements
• Office workers
• Athletes
• Manual laborers

Without proper treatment, symptoms may gradually worsen and interfere with daily activities.

At Magnum Physiotherapy, our evidence-based treatment programs focus on reducing inflammation, improving tendon mobility, restoring strength, and helping patients return to pain-free function.

Anatomy Involved

First Dorsal Compartment of the Wrist

A tunnel located on the thumb side of the wrist that contains:

Abductor Pollicis Longus (APL)

Responsible for moving the thumb away from the hand.

Extensor Pollicis Brevis (EPB)

Responsible for extending the thumb.

Tendon Sheath

A protective covering that allows tendons to glide smoothly.

Inflammation or thickening of this sheath contributes to De Quervain's Tenosynovitis.

Radial Styloid Process

A bony prominence on the thumb side of the wrist where symptoms are commonly felt.

Common Symptoms

• Pain on the thumb side of the wrist
• Tenderness near the base of the thumb
• Pain with gripping or pinching
• Pain when lifting objects
• Swelling near the wrist
• Difficulty holding items
• Reduced thumb strength
• Clicking or snapping sensation during thumb movement
• Pain radiating into the forearm

Symptoms often worsen with repetitive hand or thumb activities.

Causes & Risk Factors

Repetitive Overuse

Common activities include:

• Lifting children
• Repetitive gripping
• Typing
• Gardening
• Sports involving repetitive wrist movement

Direct Trauma

An injury to the wrist may trigger inflammation around the tendons.

Hormonal Changes

May contribute to increased risk during:

• Pregnancy
• Postpartum period

Risk Factors

• Repetitive hand use
• Female gender
• Age 30–50 years
• New parenthood
• Occupational repetitive strain

Conditions Associated with De Quervain's Tenosynovitis

• Repetitive Strain Injury (RSI)
• Tendinitis
• Wrist Pain
• Thumb Arthritis
• Carpal Tunnel Syndrome
• Postpartum Wrist Pain

Diagnosis

Diagnosis is usually based on history and physical examination.

Clinical Assessment

Evaluation includes:

• Pain location
• Thumb movement
• Wrist function
• Functional limitations

Finkelstein Test

A common orthopedic test used to identify De Quervain's Tenosynovitis.

Pain on the thumb side of the wrist during the test is often considered a positive finding.

Imaging Studies

Imaging is not always required but may include:

Ultrasound

To evaluate tendon inflammation.

MRI

For complex or persistent cases.

At Magnum Physiotherapy, we assess:

• Wrist mobility
• Thumb function
• Grip strength
• Functional limitations
• Activity-related symptoms

Treatment at Magnum Physiotherapy

Most cases respond very well to conservative physiotherapy treatment.

Pain & Inflammation Management

Activity Modification

Reducing aggravating activities helps decrease tendon irritation.

Ice Therapy

May be recommended during acute flare-ups.

Education

Patients learn strategies to reduce tendon overload.

Manual Therapy

May include:

• Soft Tissue Mobilization
• Myofascial Release
• Tendon Mobilization Techniques

These techniques help improve tendon movement and reduce pain.

Stretching Exercises

Target:

• Thumb tendons
• Wrist muscles
• Forearm muscles

Improves flexibility and tendon mobility.

Strengthening Exercises

Focus on:

• Thumb muscles
• Wrist stabilizers
• Forearm muscles
• Grip strength

Progressive strengthening helps prevent recurrence.

Ergonomic & Activity Modification Training

Addresses:

• Workplace setup
• Child lifting techniques
• Sports mechanics
• Daily activity modifications

Advanced Physiotherapy Treatments

Depending on patient needs:

• Class IV Laser Therapy
• Therapeutic Ultrasound
• TENS Therapy
• Interferential Therapy (IFT)
• Kinesiology Taping

Medical Management

If symptoms persist, additional medical treatments may include:

Splinting

Thumb spica splints help reduce tendon irritation.

Corticosteroid Injections

May reduce inflammation and provide symptom relief.

Surgical Release

Considered when conservative treatment fails.

The procedure releases the tight tendon sheath to allow normal tendon movement.

Post-surgical physiotherapy helps restore mobility and strength.

Benefits of Physiotherapy for De Quervain's Tenosynovitis

• Reduces pain
• Decreases inflammation
• Improves thumb mobility
• Restores grip strength
• Enhances wrist stability
• Improves tendon function
• Supports return to work
• Supports return to sports
• Reduces recurrence risk
• Improves overall hand function

Recovery & Prognosis

Recovery depends on:

• Severity of symptoms
• Duration of the condition
• Activity modification
• Participation in rehabilitation

Typical Recovery Timeline

Mild Cases

• 2–6 weeks

Moderate Cases

• 6–12 weeks

Post-Surgical Recovery

• Several weeks to a few months

Most patients achieve excellent outcomes with appropriate treatment.

Prevention Tips

• Avoid repetitive thumb strain
• Take regular breaks during repetitive tasks
• Use proper lifting techniques
• Maintain wrist and thumb strength
• Optimize workstation ergonomics
• Address symptoms early

When Should You Seek Medical Attention?

Consult a healthcare professional if you experience:

• Persistent wrist pain
• Pain at the base of the thumb
• Difficulty gripping objects
• Swelling around the wrist
• Symptoms that interfere with daily activities

Early treatment can prevent worsening symptoms and improve recovery outcomes.
