Acute suppurative arthritis, an inflammation of a joint caused by pyogenic organisms, occurs in all age groups but is more common in neonates, infants, and children less than 3 years of age. The hip is the most commonly involved joint, followed in frequency by the knee and the elbow. Any joint can be involved. Simultaneous infection of more than a single joint can occur.
Bacteria may access the joint through hematogenous transmission, from direct extension of infection from an adjacent area of infected metaphyseal bone, or via direct inoculation during arthrocentesis, or accidentally during femoral venipuncture. The etiologic organisms encountered in septic arthritis vary with the age of the child (Table 13,2-1). The relative frequency of Haemophilus influenzae is decreasing as a consequence of immunization practices.
