EpistemisPainful clubbing
Specialty: Musculoskeletal.
Why it occurs
- Primary hypertrophic osteoarthropathy (pachydermoperiostosis, rare genetic origin)
- Non-small cell bronchogenic carcinoma (most common cause of secondary hypertrophic osteoarthropathy or Pierre Marie-Bamberger Syndrome)
- Chronic suppurative lung disease (bronchiectasis, lung abscess, empyema)
- Cyanotic congenital heart disease or subacute infective endocarditis
- Inflammatory bowel disease (Crohn's disease, ulcerative colitis)
- Liver cirrhosis or primary biliary cholangitis
Initial workup
X-ray of hands, forearms, feet and legs (shows symmetrical and bilateral periosteal reaction of the long bones without joint involvement) | High-resolution chest x-ray and CT (essential step to rule out lung neoplasia) | Bone scan with Technetium-99.
red flags
Rapid onset of bulbous thickening of the fingers and toes with continuous burning and dull pain in the long bones of the forearms and legs, which worsens when standing, associated with chronic cough, hemoptysis or accelerated weight loss (suggests primary lung cancer).
Standard management
- Naproxen — 500 mg every 12 hours orally; effective in mitigating bone pain induced by periostitis of osteoarthropathy
- Celecoxib — 200 mg every 24 hours orally
- Pamidronate disodium — 30 mg IV infused in severe refractory cases to decrease painful periosteal remodeling
- Specific treatment of the underlying lung or visceral pathology (resolution of clubbing after resection of the lung tumor).
