Osteomyelitis

From Mediwikis
This page needs more content, you can help out Mediwikis by adding to it
  • Spread- Haematogenous from previous infection elsewhere in the body, or by direct infection e.g. during surgery.
  • Pathology- Staphylococcus causes 90% of these cases. It is often implicated in Diabetic feet, where trauma is not noticed by the patient until the bone surface is exposed.
  • Symptoms- Subacute, boring, localised bone pain, with erythema and tenderness and fever.
  • Investigations- X-Ray changes(oedema) may not be present until 14 days after infection, MRI is more sensitive. Blood cultures, and bone biopsies and cultures will also grow staphylococci.
