EpistemisPain in the anatomical snuffbox
Specialty: Musculoskeletal.
Why it occurs
- Fracture of the carpal scaphoid bone (typically after falling on the hand in hyperextension)
- Tenosynovitis of the tendons of the first dorsal compartment (De Quervain)
- Osteoarthritis of the trapeziometacarpal joint (advanced rhizarthrosis)
- C6 cervical radiculopathy with distal involvement of the thumb
- Pseudoarthrosis or avascular necrosis of the scaphoid (Preiser's Disease)
- Neuropathy of the superficial branch of the radial nerve (compression cheilitis)
Initial workup
Scaphoid-specific radiological series (AP, lateral, oblique and AP views with ulnar deviation) | Wrist MRI (gold standard for diagnosing occult scaphoid fracture in the first 48 hours) | Wrist CT if evaluation of bone displacement or healing is required.
red flags
Intense pain after a fall in hyperextension with functional impotence of the wrist, marked local swelling and weakness for the clamp, even if the initial x-rays are reported as normal (high risk of scaphoid pseudoarthrosis and subsequent carpal collapse if not immobilized).
Standard management
- Dexketoprofen — 25 mg every 8 hours orally for initial post-traumatic analgesic control
- Tramadol — 50 mg orally every 8 hours if the pain is moderate and the limb is immobilized with a thumb spica cast splint
- Paracetamol (1 g every 8 hours orally as a basic analgesic).
