What should you know about primary sternal osteomyelitis?

Primary sternal osteomyelitis is a bone infection in the breastbone that needs timely medical assessment and treatment. It is called primary when it develops without a nearby operation, injury or spreading infection being the obvious starting point.

The sternum sits at the front of the chest and connects with the ribs. Infection there may cause focal pain, tenderness, swelling, warmth or a wound that drains. Fever or feeling generally unwell may occur, but their absence does not exclude a bone infection. Other chest conditions can feel similar, so examination and investigations are needed.

A clinician may use blood tests and imaging to assess the bone and surrounding tissues. A sample may help identify the organism and guide treatment. Care can involve antimicrobial medicine, wound management and, when infected or damaged tissue needs removal or reconstruction, specialist surgery.

Arrange urgent medical review for new persistent pain or swelling over the breastbone, particularly with fever, drainage or increasing redness. Do not squeeze a wound or apply leftover medicine. Keep any opening clean and covered as advised, and tell the clinician about recent infections, injections, skin breaks and medicines that affect immunity.

Treatment is planned around the examination and test results. Follow the full prescribed course and attend wound or surgical reviews. If bone or soft tissue has been lost, reconstruction may be discussed; bone grafting is one possible surgical technique, selected only when appropriate.

Go to emergency care for trouble breathing, confusion, fainting, rapidly spreading redness, severe chest pain or a sudden deterioration. These signs can indicate a serious chest infection or another urgent condition. Even without those symptoms, worsening tenderness, pus or fever warrants same-day clinical advice.

Ask which tests are needed, whether a sample will guide treatment, how long monitoring may continue and which symptoms should trigger emergency help. Ask how to protect the wound, when activity can resume and whether an infectious-disease, surgical or wound-care specialist should be involved.
