Outcome comparison in traumatic lower-extremity reconstruction by using various composite vascularized bone transplantation.

Lower-extremity injury may present as a composite soft-tissue and bone defect, resulting directly from trauma or subsequent debridements. These composite defects often require vascularized osteocutaneous flaps for an effective, staged reconstruction. Among various donor sites, the vascularized fibular flap is generally considered the best option because of its inherent advantages. However, when the fibular flap is not available, iliac and rib flaps become the alternative choices. The purpose of this retrospective study was to compare the functional results of the alternatively chosen bone flaps (iliac and rib flaps) with those of the fibular flaps.
