Pyogenic flexor tenosynovitis due toKingella kingaein an infant

Abstract

Pyogenic flexor tenosynovitis is relatively common but is seldom reported in young children.Kingella kingaeis increasingly recognised as a causative agent. We report on an infant who presented with a palmar deep space infection and pyogenic flexor tenosynovitis caused byK. kingae.K. kingaeis a fastidious, often culture-negative, organism which has been increasingly recognised as a cause of paediatric orthopaedic infections, including flexor tenosynovitis. Clinical suspicion should be heightened, and antibiotic coverage broadened in the setting of a positive physical examination and negative blood cultures.
