Figure 1.

Schematic diagram illustrating the surgical procedure for peroneal artery perforator-based propeller flap isolation. Dissection of the perforator enables rotation and allows sufficient mobility so that a fasciocutaneous flap can be isolated and is then rotated 180° like a ‘propeller’. The opened section caused by the rotated flap being moved away from its point of origin is then closed with direct suturing or skin grafting. (A) The proximal point of the propeller flap; (B) the pivot point of the flap (the position of the peroneal perforator); and (C) the distal point of the wound. The arrows indicate the clockwise or anticlockwise rotation of the flap. The colour version of this figure is available at: http://imr.sagepub.com.
