NATIVE JOINT SEPTIC ARTHRITIS Epidemiology

NATIVE JOINT SEPTIC ARTHRITIS Epidemiology

Bacterial infection of native joints occurs with an estimated incidence of 4–10 per 100 /uni00A0 000 population per year in western Europe, with higher rates associated with socioeconomic deprivation and in developing countries. The condition most characteristically a ff ects patients at extremes of age, usually with pre-existing arthropathy or immunocompromise ( Table 43.2 Joint infection may arise as a result of haematogenous dis semination of bacteria from another focus (e.g. endocarditis) or may occur as a result of direct inoculation or local exten sion from an infected source (e.g. traumatic wound or adjacent osteomyelitis).
