Development of septic arthritis by hematogenous seeding in a pediatric patient with burns.
We describe a pediatric patient with burns who experienced a septic hip joint from hematogenous seeding by sustained Staphylococcus aureus bacteremia. A search for a central vascular focus of the bacteremia included the use of an indium scan, which localized purulence within the left hip joint. The physical findings, radiographic findings, and subsequent aspiration of the hip joint were diagnostic for a septic arthritis. This case alerts the physician that the pediatric hip is a potential site for infection in the presence of bacteremia. Once infected, the joint may become a secondary source of an ongoing bacteremia. The diagnostic work-up and treatment for a septic hip have been discussed. This occult site of infection is easy to overlook because a painful hip joint in the pediatric patient with burns may be confused for painful burn wounds. The prerequisites to joint infections in this population were all present: bacteremia, intercurrent illness, unique vascular anatomy, and an impaired immune response.
