    Abstract:
    BACKGROUND: The deep iliac circumflex artery (DICA) perforator (DICAP) chimeric flap is a valuable treatment strategy for single-stage reconstruction of composite bone and soft-tissue defects in upper and lower extremities. However, its utilization rate remains low owing to anatomical variations that lead to challenges when identifying and dissecting perforators. METHODS: A comprehensive anatomical investigation was conducted on the DICA system by injecting lead oxide into 12 fresh cadavers following a standardized procedure. From January 2008 to December 2020, 30 patients with composite bone and soft-tissue defects received reconstruction surgery with DICAP chimeric flap. One of the four specified surgical techniques was used to create a modified DICAP chimeric flap for the patients based on the size, shape, and location of the defect. RESULTS: Two branching patterns of DICA, transverse and ascending branches, were observed, and the former gave off the osteomusculocutaneous perforators and terminal musculocutaneous perforators. Thirty DICAP chimeric flaps were elevated successfully. The size of the skin paddles measured from 9 × 4.5 cm to 22 × 9 cm, and the bone components ranged from 3 × 2.5 × 1.5 cm to 6 × 3.5 × 2 cm. All flaps survived successfully after the operation, and all patients achieved primary closure of the donor sites. No patient encountered the fracture of transferred iliac segments. The mean bone union time was 5.5 months (ranging from 4 to 8 months). CONCLUSION: The DICA system is a suitable source for harvesting the DICAP chimeric flap to reconstruct composite bone and soft-tissue defects. It provides a flexible design for individualized coverage of such defects with limited donor-site morbidity.
