De Quervain's Disease

Overview

De Quervain's disease is a specific type of tenosynovitis that affects two tendons that control movement of the thumb: the abductor pollicis longus (APL) and the extensor pollicis brevis (EPB). These tendons run through a tunnel-like compartment (the first dorsal compartment) on the thumb side of the wrist. When these tendons or their surrounding sheath become inflamed, thickened, or swollen, movement becomes painful and difficult.

The condition is characterized by pain and tenderness at the base of the thumb, which typically worsens with thumb and wrist movement. The inflammation restricts the smooth gliding of the tendons through their sheath, similar to how a rope might have difficulty sliding through a pulley when the rope is frayed or the pulley is too tight. This mechanical problem leads to the characteristic catching, sticking, or sharp pain experienced by those with the condition.

De Quervain's disease is one of the most common forms of tenosynovitis, affecting approximately 0.5% to 1.3% of the general population. It's particularly prevalent among new mothers (hence the colloquial term "mother's wrist" or "mommy thumb"), individuals who perform repetitive hand motions, and increasingly, those who frequently use smartphones and gaming devices. While the condition can be quite painful and limiting, it typically responds well to conservative treatment when caught early, with most patients experiencing significant improvement within weeks to months.

Symptoms

The symptoms of De Quervain's disease typically develop gradually, though they can sometimes appear suddenly after acute overuse or injury. The hallmark symptom is pain on the thumb side of the wrist, but the condition affects individuals differently in terms of severity and specific manifestations.

Primary Symptoms

• Wrist pain - Sharp or aching pain on the thumb side of the wrist
• Hand or finger pain - Pain radiating into the thumb and sometimes up the forearm
• Pain that worsens with thumb and wrist movement
• Difficulty gripping or pinching objects
• Pain when turning the wrist or making a fist

Swelling and Inflammation

• Wrist swelling - Visible swelling over the thumb side of the wrist
• Hand or finger swelling - May extend into the thumb area
• Tenderness when pressing on the affected area
• Warmth over the inflamed tendons
• A fluid-filled cyst may develop along the tendon sheath

Movement-Related Symptoms

• Abnormal involuntary movements - Catching or snapping sensation with thumb movement
• Difficulty moving the thumb smoothly
• Stiffness, especially in the morning
• Squeaking or crepitus with tendon movement
• Weakness in the thumb and difficulty with fine motor tasks

Referred and Associated Symptoms

• Arm pain - Pain may radiate up the forearm
• Shoulder pain - Compensatory movements may cause secondary pain
• Numbness or tingling (if nearby nerves are affected)
• Muscle fatigue from altered use patterns

Functional Limitations

• Difficulty with activities requiring thumb movement:
  • Lifting objects, especially with the thumb extended
  • Opening jars or turning doorknobs
  • Writing or typing
  • Texting or using smartphones
  • Caring for infants (lifting, changing diapers)

Symptom Progression

Without treatment, symptoms typically:

• Start as mild discomfort with specific activities
• Progress to pain with most thumb movements
• Eventually cause pain even at rest
• May lead to chronic changes if untreated

Causes

De Quervain's disease occurs when the tendons controlling thumb movement become irritated and inflamed within their protective sheath. While the exact cause isn't always identifiable, several factors can contribute to the development of this condition.

Primary Mechanical Causes

Overuse and Repetitive Motions

• Repetitive hand and wrist movements that involve:
  • Gripping while moving the wrist side to side
  • Pinching with the thumb while moving the wrist
  • Repeated thumb extension and abduction
  • Wringing or twisting motions
• Activities commonly associated with De Quervain's:
  • Texting and smartphone use ("texting thumb")
  • Gaming (console or computer)
  • Racquet sports (tennis, badminton)
  • Gardening and landscaping
  • Knitting, sewing, and crafts
  • Playing musical instruments

Direct Trauma

• Direct blow to the thumb or wrist
• Sudden wrenching or jamming of the thumb
• Falls onto an outstretched hand
• Sports injuries affecting the wrist

Anatomical and Biomechanical Factors

• Tendon sheath thickening: Repeated irritation causes the sheath to thicken
• Synovial inflammation: The lining of the tendon sheath becomes inflamed
• Anatomical variations: Some people have naturally tighter compartments
• Presence of septum: Additional bands within the compartment
• Accessory tendons: Extra tendon slips can crowd the space

Hormonal and Systemic Causes

Pregnancy and Postpartum

• Hormonal changes affecting connective tissue
• Fluid retention causing tissue swelling
• Repetitive motions of infant care
• Lifting and carrying babies in awkward positions

Medical Conditions

• Rheumatoid arthritis: Inflammatory changes in tendons

Diagnosis

Diagnosis of De Quervain's disease is primarily clinical, based on patient history and physical examination. Imaging studies are typically not necessary but may be used to rule out other conditions or confirm the diagnosis in unclear cases.

Clinical History

Key Questions During Evaluation

• Location and nature of pain
• Activities that trigger or worsen symptoms
• Duration and progression of symptoms
• Previous injuries to the hand or wrist
• Occupational and recreational activities
• Previous treatments attempted
• Associated symptoms (numbness, tingling)

Physical Examination

Inspection and Palpation

• Visual inspection for swelling over the first dorsal compartment
• Palpation for tenderness along the radial styloid
• Assessment for thickening of the tendon sheath
• Checking for crepitus with thumb movement
• Evaluation of thumb and wrist range of motion

Finkelstein Test

The most specific diagnostic test for De Quervain's:

• Patient makes a fist with thumb tucked inside fingers
• Wrist is bent toward the little finger (ulnar deviation)
• Positive test: Sharp pain along the thumb side of wrist
• High sensitivity but can be positive in other conditions

Modified Finkelstein Test (Eichhoff's Test)

• Examiner grasps the patient's thumb
• Passive ulnar deviation of the wrist
• May be more comfortable for patients
• Equally diagnostic

Other Clinical Tests

• Brunelli test: Pain with resisted thumb extension
• Grind test: To rule out thumb arthritis
• Wrist hypermobility assessment: Check for ligament laxity
• Neurological examination: Rule out nerve compression

Imaging Studies
