Abstract：Objective To investigate the surgical method and curative effect of treating chronic sternum osteomyelitis after cardiac surgery with repairing transfer of pectoralis major muscle flap. Methods The patients with chronic sternum osteomyelitis after cardiac surgery (n=56) were chosen from Jan. 2008 to Aug. 2014, and among them 36 with simple sternum osteomyelitis, 11 with sternum osteomyelitis accompanied by costal chondritis and 9 with sternum osteomyelitis accompanied by suppurative infection in mediastinum. During the cardiac surgery, complete debridement and removing source of infection were carried out, and enough pectoralis major muscle flap was transferred to fill sternum defect. Negative pressure drainage was applied continuously and sensitive antibiotics were administered for preventing infection after cardiac surgery. The clinical efficacy was observed and followed up. Results All patients were followed up for 4 m to 12 m (averagely 8 m). There were 51 patients (91.1%) with phase I healing of incision, 3 (5.3%) with a few secretion at drainage outlet and healed after dressing changes for 1 w, and 2 (3.6%) with poor incision healing and cured after cardiac surgery again. There were no patients with incision re-infection, formation of chronic sinus tract and recrudescence of sternum osteomyelitis. All patients had normal functions of upper limbs. Conclusion The curative effect of repairing transfer of pectoralis major muscle flap is reliable in treatment of sternum osteomyelitis after cardiac surgery without more incisions, which is suitable for clinical application.
