Propeller Flaps in the Posterior Trunk

The reconstruction of complex posterior trunk defects remains challenging. But now with an increased knowledge of angiosomes and the practice of perforator flaps, the posterior trunk offers a new plethora of options for reconstruction. Propeller flaps based on such perforator(s) offer an elegant solution for managing defects while achieving primary donor-site closure without significant morbidity. We will discuss the relevant anatomy and design principles for propeller flaps based on a review of the literature and our experience. Steps beginning with preoperative planning, perforator selection, and intraoperative surgical technique will be discussed, together with pearls on both avoiding and managing complications.
