Objective To investigate the effectiveness of the combination of the anterolateral thigh perforator (ALTP) flap and other flaps for repairing the extreme circumferential defects on the limb. Methods Between October 2016 and June 2019, 9 patients with the extreme circumferential defects on the limb were admitted, which resulted by degloving injury, including 8 males and 1 female with a median age of 42 years (range, 32-65 years). The etiology involved twist injury in 5 cases, traffic accident in 2 cases, and high voltage electric injury in 2 cases. The location of the defects was left forearm in 2 cases, right forearm in 3, left foot in 3, and right foot in 1. The injected wound bed followed by the exposure of bone, joint, tendon, and blood vessel. The dimension of defects was 25 cm×20 cm to 40 cm×28 cm. The period between the injury and admission was 1-12 hours (mean, 5 hours). All contaminated wounds were taken thorough and radical debridement and covered by the vacuum sealing drainage device during the emergency operation. The ALTP flap and the other one flap were tailored according to the dimension of the wound when the wound surface became granulating, including the thoracodorsal artery perforator (TAP) flap in 3 cases, superficial inferior epigastric artery perforator flap in 3 cases, superficial circumflex iliac artery perforator flap in 3 cases. And the donor site was primary closure. Results After operation, all the flaps survived except 1 case of partial necrosis at the edge of TAP flap and healed after secondary skin grafting, and the wounds in the donor and recipient areas healed by first intention. All patients were followed up 14-24 months (mean, 16 months). The shape of the flap was satisfactory and the texture was soft. There was no abnormal hair growth and obvious pigmentation during the follow-up. Only linear scar was left in the donor area, there was no complication such as abdominal wall hernia, and the activity of hip and knee was not affected. The functional reconstruction of upper limb and ankle was satisfactory, and the disabilities of the arm, shoulder, and hand (DASH) score was excellent in 4 cases and good in 1 case; the American Orthopaedic Foot and Ankle Association (AOFAS) score was excellent in 3 cases and good in 1 case. Conclusion ALTP flap combined with different flaps can reconstruct the circumferential extreme defects after limb damage in one-stage, which can achieve limb salvage to the greatest extent.
