title: Vascularized iliac osteocutaneous flap based on the deep circumflex iliac vessels: experience in 13 cases.
abstract: We have carried out 13 vascularized iliac osteocutaneous flaps (VIOF) based on the deep circumflex artery (DCIA) and accompanying veins for cases with compound skin and bone defects. Ten of 13 cases obtained bony union at both ends of the iliac crest with only VIOF. Two of the remaining 3 cases obtained bony union at one end only with the VIOF but united at another end with an additional conventional bone grafting procedure. The final case, a traumatic bone defect of the tibia, failed to obtain bony union at either end of the iliac segment. In 5 of 11 patients in which an osteocutaneous flap was used, complete skin flap survival occurred. Of the remaining 6, one flap went on to complete necrosis, and five flaps were complicated by superficial or partial necrosis. The incidence of flap complications was analysed according to the size of flap. Five flaps with complete survival averaged 6.8 x 10.6 cm in size; however, five flaps with superficial or partial necrosis averaged 10.0 x 15.8 cm. These results suggest that the maximal safe skin flap dimension from the DCIA supply alone is probably 10 x 15 cm.
