Free Combined Anterolateral Thigh Flap and Vascularized Iliac Bone Graft with Double Vascular Pedicle

ABSTRACT

Although free vascularized iliac bone graft has been successfully used for the reconstruction of large bone defect with microvascular surgery, there is a serious problem of how to repair in one-stage, those cases having a large bone defect with a very wide skin defect. A free combined anterolateral flap and vascularized iliac bone graft with double vascular pedicles seems to be a most suitable method for cases having both large bone and skin defects. Two case reports are presented in which this flap was used. Based on the authors' cases, the advantages of this flap are its thinness and the extreme wideness of the skin territory. The anatomy of the pedicle vessels is large and long, and the donor scar can be made in an unexposed area. This flap can be considered for use in one-stage reconstructions of both large bone and skin defects in the oral and leg regions.
