Review article: Paediatric bone and joint infection.

Paediatric musculoskeletal infection remains an important cause of morbidity. Methicillin sensitive Staphylococcus aureus is still the most common organism although the incidence of methicillin resistant S. aureus in the community is rising. Osteomyelitis and septic arthritis due to Haemophilus influenzae is decreasing in incidence secondary to immunisation and in some units has been replaced by infections with the gram negative bacillus, Kingella kingae. Recent prospective studies indicate that uncomplicated osteomyelitis can be treated by three to four weeks of antibiotics. However, there is still a small group of children who will have overwhelming disseminated infection. These children require aggressive surgical and medical intervention. Two recent reports have identified an increased incidence of septic arthritis in children who have hemophilia and are HIV positive.
