De Quervain's Tenosynovitis

De Quervain's tenosynovitis is a painful condition affecting the tendons on the thumb side of the wrist. It occurs when the tendons that move the thumb — the abductor pollicis longus and extensor pollicis brevis — become irritated and inflamed within their tight fibrous sheath, causing pain and swelling near the base of the thumb.

Causes and Risk Factors

De Quervain's is most commonly caused by repetitive hand and wrist motions that involve gripping, pinching, or twisting — such as lifting a baby, gardening, racquet sports, or prolonged smartphone use.

It is more common in women, particularly during and after pregnancy, and in individuals between ages 30–50. Inflammatory conditions such as rheumatoid arthritis can also predispose to this condition.

Treatment

Initial treatment includes thumb spica splinting to immobilize the thumb and wrist, activity modification, and anti-inflammatory medications. Corticosteroid injection into the tendon sheath is highly effective and often provides lasting relief.

When conservative measures fail after 3–6 months, surgical release of the first dorsal compartment is performed as an outpatient procedure. Dr. Kinchelow carefully releases the tight sheath to allow the tendons to glide freely, with rapid return to activity expected.

Common Symptoms

  • Pain and swelling at the base of the thumb
  • Positive Finkelstein test
  • Difficulty pinching or gripping
  • Catching or snapping sensation with thumb movement
  • Tenderness along the radial wrist
  • Pain that radiates into the thumb or forearm

Treatment Options

  • Thumb spica splinting
  • NSAIDs and activity modification
  • Corticosteroid injection into the tendon sheath
  • Occupational therapy
  • First dorsal compartment surgical release
  • Post-surgical rehabilitation
