Which flap options are described for reconstruction after sternum debridement due to osteomyelitis?

• A. Pectoralis Major Muscle Flap Or Serratus Anterior Muscle Flap Or Omental Flap
• B. Latissimus Dorsi Flap Or Rectus Abdominis Flap
• C. Free Skin Grafts Only
• D. No Reconstruction Is Ever Needed

Answer: (A)

Reconstructing the sternum after debridement for osteomyelitis relies on bringing in vascularized tissue to fill dead space, protect the mediastinal contents, and help fight infection. The described flap options fit this purpose well: the pectoralis major muscle flap can be advanced to cover anterior chest defects, the serratus anterior muscle flap can help address lateral-to-anterior coverage, and the omental flap provides a highly vascular, immune-active tissue that can be transposed into the chest to seal the space and resist infection. Together, they offer durable, well-vascularized coverage essential for healing after sternum debridement. Free skin grafts alone cannot provide the necessary bulk or blood supply to manage infection and protect underlying structures, which is why they are not suitable as the primary reconstructive method here. While other chest-wall flaps such as latissimus dorsi or rectus abdominis can be used in broader chest-wall reconstructions, the options described—pectoralis major, serratus anterior, and omental flaps—are the ones specifically described for sternum defects after osteomyelitis.
