Repair of ankle soft tissue defect with anterolateral thigh perforator flap or free saphenous artery perforator flap / 中华显微外科杂志

ABSTRACT

Objective To evaluate the surgical technique and clinical significance of the therapy for ankle soft tissue defect with 2 different flee perforator flaps.Methods Twenty-five cases of ankle soft tissue defect with exposed bone of the ankle were involved in this study from August 2006 to April 2012.and the wound sizes varied from 4.0 cm × 5.5 cm to 11.0 cm × 23.0 cm.Twenty cases with acrotarsium soft tissue defect were repaired by free anterolateral thigh perforator flap,five cases with pelma soft tissue defect were repaired by free saphenous artery perforator flap.Results All Twenty-five flaps survived.At 3 to 50 months follow-up [on an average of (18.0 ± 0.8) months] postoperatively,appearance of the flaps was satisfactory,with 10 to 22 mm in 2-PD,and the sensation percentage beyond S2+ was 13/20 cases and 5/5 cases at 3 months follow-up,respectively.Conclusion The optimal therapy for the acrotarsium soft tissue defect is the free perforator anterolateral thigh flap,and free saphenous artery perforator flap should be used for pelma soft tissue defect.Avoid secondary orthopaedic surgery,pay more attention to the donor site of the flap.VSD can significantly promoting the survival rates of the free perforator flaps if the soft defects are caused by open injury.
