Acute Bacterial Osteomyelitis in Children

Purpose To review the records of 24 paediatric patients treated for acute bacterial osteomyelitis.Methods Records of 14 male and 10 female paediatric patients (mean age, 9.4 years) who underwent medical treatment alone (n=3) or combined with surgery (n=21) for acute bacterial osteomyelitis were reviewed. Medical treatment included use of antibiotics and supportive care. Surgery was indicated when the largest dimension of fluid collection was >1 cm.Results Of the 24 patients, Staphylococcus aureus was isolated in 18, group-D salmonella in 3, and no organism in 3. The mean time from admission to diagnosis was 1.87 days. For those treated surgically, the mean time from diagnosis to surgery was 1.19 days and the mean time from admission to surgery was 2.86 days. Four patients underwent multiple surgeries, 2 of whom developed chronic osteomyelitis and also had negative culture and delayed surgery by >10 days previously. No other patient had any complications.Conclusion Early surgical intervention for acute bacterial osteomyelitis in children increased diagnostic yield with cultures. For patients with fluid collection <1 cm in the largest dimension, medical treatment alone was effective. Patients with complications were characterised by negative culture, multiple surgeries, and delayed surgery.
