Objectives/Interrogation: To investigate the clinical effect of free iliogroin flap in repairing soft tissue of extremities and combining bone defect.

Methods: From January 2010 to June 2017 75 cases performed with free iliogroin flap to repair skin and soft tissue defect of extremities, including 42 cases of superficial circumflex iliac artery flap (13 with ilium superficial circumflex iliac artery flap, superficial 18 were epigastric artery flap, 15 cases of superficial circumflex iliac artery and the superficial epigastric artery combined the flap (lobulated flap in 7 cases). 49 cases of hand and skin soft tissue defects were repaired, 26 cases of skin and soft tissue defects were repaired, 18 cases were toe reconstruction, and the smallest area was 5.0 cm *7.0 cm, the largest was 11.0 cm * 23.0 cm. All repair superficial circumflex iliac vein or superficial circumflex iliac vein (21 cases of repair and a concomitant vein). The donor site is directly sutured through flexion and hip flexion. The occurrence of arteriovenous crisis and the principle of treatment were observed within 1 weeks after the operation. After 3 weeks, 1.5 months, 3 months, 6 months, 1 years and 2 years follow-up, we observed the healing of the donor site and the appearance and sensory recovery of the skin flap, and summarized the clinical application characteristics and experience of the flap.

Results and Conclusions: In 75 cases of skin flap, 72 cases survived smoothly, 1 cases had arterial crisis, 2 case had venous crisis, and skin necrosis occurred after conservative treatment. After two stage eschar, subcutaneous soft tissue survived and skin graft survived. A flap cut was removed after a week straight walk for area after two incision dehiscence and suture after healing, healed more than. After 0.5 - 1.5 years of follow-up, the skin flap was soft, mild and bloated, and the sensation recovered S2-S3, and the line scars in the abdominal donor area were small. The use of free iliac inguinal flap transplantation to repair skin and soft tissue defects of extremities is an axial skin flap. It has a constant blood vessel and easy cutting. It does not damage main vessels. The operation time is short, the flap is large, the donor area can be directly sutured, and the scar is small and hidden. It is one of the better methods to repair the soft tissue defects of the extremities.
