Which statement best describes the role of muscle or omental flaps in sternum osteomyelitis management?

• A. They Provide Soft-Tissue Coverage After Debridement
• B. They Are Never Used
• C. They Are Preferred Only For Cosmetic Reasons
• D. They Replace The Sternum With Prosthetic Material

Answer: (A)

The main idea is that in deep sternal infections, after thorough removal of infected bone and tissue, the key step is bringing in well-vascularized soft tissue to cover the area. Muscle or omental flaps are used because they provide rich blood supply to the wound, help deliver antibiotics and immune cells directly to the infected site, fill dead space, and shield exposed mediastinal structures from ongoing contamination. This vascularized coverage converts an uncontrolled infection into a manageable one and supports healing and chest-wall stability. They are not chosen for cosmetic reasons and they do not replace the sternum with a prosthetic material; rather, they serve to cover and vascularize the area after debridement, with the option of using a muscle flap such as pectoralis major or an omental flap depending on the defect.
