PY - 2009 T2 - Pediatric Practice: Infectious Disease AB - Septic, pyogenic, and suppurative arthritis are the names given to the inflammation of the joint space caused by the presence of bacteria or fungi. Septic arthritis is more common in childhood than in any other period of human life and more than half of cases are diagnosed in individuals younger than 20 years of age. Since septic arthritis usually has a hematogenous origin, the age distribution of pediatric patients with joint infection is markedly skewed, reflecting the increased attack rate of bacteremia in early childhood. In a large series of 725 pediatric patients with joint infections compiled by Trujillo and Nelson, 52% of the children were younger than 2 years, 25% were aged 2–5 years, 15% were 6–10 years old, and the remaining 6% were aged 11–15 years.1 Since a significant fraction of suspected cases of septic arthritis remains bacteriologically unconfirmed, the true incidence of the disease is uncertain. The estimate annual incidence of the disease in the general population ranges between 2 and 10 cases per 100,000.2 Several pediatric subpopulations are at increased risk for septic arthritis, as summarized in Table 48–1.
