Objective To explore the clinical efficacy of anterolateral thigh flap transplantation in the repair of skin and soft tissue defects of the feet and ankles in children. Methods From January 2017 to October 2018, the anterolateral thigh flaps were used to repair skin and soft tissue defects of the feet and ankles in 7 children. The defect area ranged from 3.0 cm×4.5 cm to 4.5 cm×10.0 cm, all accompanied with exposure of tendon and bone. Preoperatively, the perforators were determined by ultrasonic doppler sonography. The anterolateral thigh flap was cut, with an area from 4.0 cm×5.5 cm to 5.5 cm×11.0 cm. The donor site wound was directly sutured in 4 cases, and intermediate split thickness skin graft was used to close the wound in 3 cases. Postoperative follow-up was conducted regularly to evaluate the appearance, texture, and functional recovery of the feet and ankles. Results All flaps survived in 7 children, and the wounds healed in the first stage. One patient experienced vascular crisis, but the flap survived after a thrombus was taken out at the anastomotic site. One case had necrosis of the distal end of the flap but healed well after dressing change. The follow-up period was from 6 to 12 months. The skin flap had good appearance and soft texture, basically consistent with the surrounding skin tissue. No edema occurred. The ankle joint had good flexion and extension function, with no effect on foot venous reflux. Conclusion The free anterolateral thigh flap has good clinical effect in the repair of skin and soft tissue defects of children's feet and ankles. [ABSTRACT FROM AUTHOR]

Objective To explore the clinical efficacy of one-stage prolongation bone graft in the treatment of first metatarsal shortness and to introduce the advantages of this surgical method. Methods The middle part of the metatarsal bone was cut off with a swing saw through the dorsal incision of the first metatarsal bone. The iliac bone was obtained for one-stage prolongation bone graft. Re原 sults All patients were followed up from 6 to 18 months. The postoperative radiographs showed that bony union was achieved in all metatarsals at 12 weeks. The average prolongation length was 1.7 cm (from 1.2 to 2.2 cm). Function was evaluated according to the standard of the American Orthopedic Foot and Ankle Society (AOFAS). The average postoperative AOFAS score was 87.5, 3 were excellent, and 2 were good. No obvious complications were found. All patients were satisfied with the prolongation results, appearance, and recovery of function in the feet. Conclusion Treatment of first metatarsal shortness with one-stage prolongation using iliac bone graft can restore the metatarsal bone to a satisfactory length. This method has a short recovery period, and complications are rare, making this procedure worth popularizing and applying in clinic. [ABSTRACT FROM AUTHOR]
