Which condition is most associated with sternum osteomyelitis due to diabetes and sternotomy?

• A. Diabetes With Median Sternotomy
• B. Hypertension With Cholecystectomy
• C. Atrial Fibrillation With CABG
• D. Asthma With Lobectomy

Answer: (A)

Diabetes markedly raises the risk of deep sternal wound infection and osteomyelitis after a sternotomy. Diabetes impairs immune function, slows wound healing, and often causes vascular disease that reduces blood flow to the sternum, making it harder to clear infection. A median sternotomy directly exposes the sternum to potential contamination during cardiac surgery, so the combination of diabetes and sternotomy is the scenario most associated with developing sternum osteomyelitis. The other options mix different conditions or procedures that don’t carry the same strong, diabetes‑driven risk for sternal bone infection.
