Vascularized iliac osteomuscular free flaps for composite soft tissue and bone defects of the lower extremity

The purpose of this study to evaluate if vascularized iliac osteomuscular free flaps, which use simple iliac graft companied by covering the iliacus muscle in the inner cortex, is a better option for soft tissue and bone defects of the lower extremity. A retrospective review was performed on 7 consecutive patients treated with vascularized iliac osteomuscular free flaps from June 1999 to March 2003. Survival of skin graft transferred onto the surface of the iliacus muscles provided indirect proof for the survival of transferred bone flap. Skin grafts survived completely in 4 cases and partially in 3 cases. The patients were followed up for 8 to 26 months (average, 14 months) and had acceptable contour and function.
