What should you know about septic osteomyelitis?

Bone infection may begin after an open injury, surgery, a nearby wound or spread through the bloodstream. Symptoms can include deep, persistent pain, warmth, swelling, reduced use of the affected area, fever or drainage from a wound. Some infections develop gradually, so the absence of fever does not exclude the problem.

Assessment may include an examination, blood tests, imaging and a sample from the affected area. The sample can help identify the germ and guide treatment. Tell the clinician about recent injuries, operations, wounds, dental problems and medicines that affect immunity.

Treatment is planned around the location, extent and cause of infection. It may include antibiotics for a clinician-selected duration, wound care and protection of the affected limb. If infected or dead tissue remains, surgery may be needed to clean the area and improve healing. Bone grafting can be discussed when infection or surgery leaves a structural gap, but it is not a substitute for controlling active infection.

Take antibiotics exactly as prescribed and attend planned reviews, even if pain improves. Keep dressings clean, avoid smoking if advised, and report new drainage or worsening pain rather than waiting for the next appointment.

Contact a clinician promptly for persistent bone pain with a wound, swelling, warmth or drainage. Seek urgent help for fever with shaking chills, rapidly spreading redness, severe weakness, confusion, fainting or inability to use the limb. A worsening wound after surgery or injury also needs timely review.

Ask which tests are needed, whether a sample will guide antibiotic choice, how long treatment is expected to continue, and whether surgery is necessary. If bone has been damaged, ask whether reconstruction or bone grafting should be considered after infection control.
