Kingella kingae osteomyelitis of the clavicle

Kingella kingae is the most recent addition to the list of etiologic agents causing osteomyelitis and septic arthritis in previously well children. A case is presented of a child with K. kingae osteomyelitis of the clavicle--an uncommon site of infection due to any organism. In the hope of facilitating the detection and treatment of this increasingly recognized pathogen, a brief discussion of its microbiologic characteristics and a summary of the patients reported to date with bone and joint infections due to this organism are included. To our knowledge, this is the first discussion of K. kingae in the orthopedic literature.
