Free latissimus dorsi flap for chest wall repair after complete resection of infected sternum.
BACKGROUND
Radical debridement, followed by muscle flap cover, has significantly reduced morbidity and mortality of infected sternotomy wounds. The pectoralis major, rectus abdominis, and greater omentum flaps are most commonly used, whereas the latissimus dorsi muscle is rarely employed.


METHODS
In 7 patients with persistent infection and necrosis of the sternum, radical and extensive debridement including the sternum, costochondral arches, manubrium and sternoclavicular joints was performed. A free latissimus dorsi flap was used for soft tissue reconstruction without additional stabilization of the chest wall.


RESULTS
All flaps survived without revision of the anastomosis. In the follow-up period (22 months to 5 years) no recurrent infection was observed. Three patients died during the study period (3 to 24 months after operation) due to causes not related to sternum operation. No additional weakness, pain, or restricted movements of the shoulders due to missing sternum was observed.


CONCLUSIONS
Our findings suggest that the use of free latissimus dorsi flap after complete sternectomy for infection has several advantages: it provides abundant tissue to allow radical and extensive debridement, obliterates completely the dead space, and helps to control infection. Even without additional chest wall reconstruction it gives enough stability to allow pain-free normal daily activities.
