[Abstract]: Objective: To study the clinical effect of the medial malleolus perforator pedicled propeller skin flap of posterior tibial artery in repairing the heel wound. Methods:From March 2016 to September 2018, the medial perforator pedicled propeller skin flap of posterior tibial artery was used to repair 22 cases of soft tissue defect in the heel region. Among them, there were 15 males and 7 females, aged from 21 to 52 years, with an average age of 33 years. Wound location: heel area; wound size: 2.5 *3 cm 2-5.7 *6.5 cm 2. Preoperative lower extremity angiography (CTA) and hand-held color Doppler ultrasound were used to locate the penetrating fulcrum accurately. Preoperative measurements of wound size were carried out to design the propeller and small propeller of the perforating pedicle propeller skin flap. During the operation, the flaps were cut according to the design. All cases were followed up for 3-12 months. Results:All the flaps survived after operation, and the rotation angle ranged from 120 to 180 with partial skin grafting in 2 cases, the wound and donor area healed in the first stage. All patients were followed up for 2 to 18 months, with an average of 14 months. The flaps have good appearance, good color, texture and elasticity, no contracture and good appearance of donor site.. Conclusion: Propeller skin flap pedicled with medial malleolus perforator of posterior tibial artery is similar to the tissue of heel posterior area. The position of medial malleolus perforator is constant. The skin flap is easy to rotate without sacrificing the main vessels. It is one of the ideal options for repairing the medial wound in heel posterior area.
