title: Tendon ruptures with scaphoid nonunion. A case report.
abstract: Intratendinous ruptures of flexor tendons about the hand and wrist are rare. Flexor pollicis longus and index flexor digitorum profundus tendon ruptures, most commonly seen in patients with rheumatoid arthritis, occurred in a nonrheumatoid 48-year-old man with an asymptomatic scaphoid nonunion. This rare injury may simulate an anterior interosseous nerve syndrome. The absence of prior symptoms does not preclude tendon rupture secondary to scaphoid nonunion. Restoration of power pinch provides good function despite limited range of motion.
