Abstract
1. Recent published reports of neonatal osteomyelitis in long bones are reviewed.
2. Six further cases are described.
3. The source of infection is usually the skin or the umbilicus, and the common organisms are the haemolytic streptococcus and staphylococcus aureus.
4. Cases fall into two groups: in one the patient is acutely ill with septicaemia and the bone lesion is of secondary importance; in the other the general condition is well maintained even though there may be multiple bone lesions.
5. Sequestration is uncommon; but when it occurs it prevents the rapid healing that is usually observed after drainage.
6. The most important complication is suppurative arthritis, which may lead to total destruction of a joint.
7. It is probable that the lowered mortality from infantile septicaemia will be matched by a corresponding increase in the cases of acute osteomyelitis encountered in clinical practice.
