32-year-old woman presents with radial wrist pain that worsens when lifting her newborn baby. Examination reveals tenderness over the radial styloid and a positive Finkelstein test. What is the most likely diagnosis?
- A Carpal tunnel syndrome
- B De Quervain's tenosynovitis ✓
- C Scaphoid fracture
- D Trigger finger
Correct answer: B. De Quervain's tenosynovitis
Explanation
De Quervain's tenosynovitis involves inflammation of the first dorsal compartment tendons. Repetitive lifting, as seen in new mothers, is a classic trigger. Finkelstein test is pathognomonic. Carpal tunnel syndrome causes median nerve distribution numbness, not localized radial styloid pain.
