Osteomyelitis therapy

The plan depends on the bone involved, how long infection has been present, the likely germ, blood supply, nearby wounds, and whether an implant or fracture is present. Blood tests and imaging help show inflammation and the affected area. Samples from blood, drainage, or bone can guide antibiotic selection; a sample may be especially useful when the first medicine does not help.

Antibiotics may be given through a vein at first or by mouth when the clinician considers that appropriate. Some infections also need drainage of pus or removal of dead bone. Wound care, pressure relief, circulation assessment, and management of conditions that slow healing may support recovery.

Take each medicine as prescribed and tell the team about allergies, new side effects, or missed doses. Attend blood tests and follow-up visits if requested; these help clinicians assess response and medicine safety. Follow instructions about weight-bearing, dressings, mobility, and physiotherapy rather than testing the area through pain.

If infection has damaged or removed part of a bone, reconstruction may be considered once the surgical team judges the infection controlled. One possible approach is [Bone Grafting](/treatments/trauma-and-fracture-care/bone-grafting/).

Contact the treating team urgently for worsening pain, renewed swelling, fever, chills, new drainage, a red or opening wound, or difficulty using the affected limb. Emergency help is needed for confusion, faintness, severe weakness, new limb numbness, or back pain with neurological symptoms.

Ask what germ is suspected, how samples will guide treatment, how long the plan may last, which activities are safe, how side effects will be monitored, and what signs could indicate persistent infection.
