Primary acute haematogenous osteomyelitis of an isolated metatarsal in children.

Acute haematogenous osteomyelitis of an isolated metatarsal is a rare condition in childhood. Fourteen children diagnosed with this condition were followed up for an average of 3 years. Organisms responsible were found to be either Staphylococcus aureus or Streptococcus pyogenes. Growth disturbances of the metatarsal were seen in the majority, but the radiographic features were not serious in the long term, and no child was subsequently disabled. Since these children often present with symptoms akin to trauma, a better recognition of the condition is required to avoid misdiagnosis.
