Reconstruction of the sternumdefect, regardless of the reason, should ensure the stability of the anterior chest wall, the return of acceptable respiratory parameters and the control of wounds. Stability of the chest wall can be provided by autogenous tissues or prosthetic materials. In our experience, the fibula free osteocutaneous flaps are harvested for reconstruction of the bone defect in two patients after full-thickness defect of the sternum and anterior chest wall.展开更多
