Acute infections of bone and joints are medical emergencies. Early diagnosis and treatment are essential for limb salvage and prevention of deformities. Data from developing countries are essential to develop region-specific treatment guidelines including choice of empiric antibiotics. We reviewed electronic medical records of children (≤ 12 years old) admitted to the pediatrics or orthopedics department of a tertiary care hospital in South India from 2013 to 2017 with a diagnosis of septic arthritis and/or osteomyelitis. Clinical, microbiological, and follow-up data were collected and analyzed. The median (interquartile range, IQR) age of the children (N = 207) was 48 (7.5-105) months. Acute infections were more common in infants, whereas chronic cases were common in children > 5 years of age. Staphylococcus aureus (71%) was the most common organism identified. Gram-negative organisms were more frequently isolated in infants compared with older children. Blood and/or wound culture positivity was 78% (N = 161) overall and 78% (N = 31) in chronic cases. The median (IQR) duration of antibiotics was 7 (5-8) weeks. Sequelae and readmissions occurred in 47% (N = 81) of the 172 patients followed for a year. Culture positivity rates especially of wound were high even after receiving antibiotics.
