Hematogenous osteomyelitis at uncommon sites in children.

The diagnosis of hematogenic osteomyelitis is often delayed in children if it involves uncommon sites such as the pelvis, clavicle, or calcaneus. Although parenterally administered antibiotics may control the disease process in the acute stage, abscess formation requires incision and drainage. Staphylococcus aureus was the most common organism in this series, and it usually was penicillin resistnat. When the condition is diagnosed early and is properly treated with at least 3 weeks of antibiotic therapy and judicious surgical intervention, recurrences are rare and morbidity is minimal.
